Tuples in Python<br />
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.097cm;padding-right:0.191cm;"| First we will learn about tuples.<br />
<br />
<br />
* Tuple is a collection of elements similar to a list.<br />
* Tuple uses parentheses, whereas list uses square brackets.<br />
* Elements of a tuple cannot be changed once it is assigned.<br />
* But in a list, elements can be changed.<br />
<br />

'''Tuple declaration'''<br />
<br />
(1, 2.5) and 1, 2.5 are same<br />
<br />
(1, ) and 1, are same<br />
<br />
((1,),) and (1,), are same<br />
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.097cm;padding-right:0.191cm;"| Here are few examples for declaring tuples.<br />
<br />
''Inside brackets'' 1, 2.5 is a tuple with two elements.<br />
<br />
The same can be declared as 1, 2.5. <br />
<br />
''Inside brackets ''1 comma is a tuple with one element<br />
<br />
The same can be declared as 1 comma <br />
<br />
''Inside brackets again inside brackets ''1 comma and outside bracket a comma is a tuple with one tuple as element.<br />
<br />
The same can be declared as ''inside brackets'' 1 comma and outside bracket a comma <br />
<br />
|-<br />
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.095cm;padding-right:0.191cm;"| Open the terminal<br />
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.095cm;padding-right:0.191cm;"| Let us start '''ipython'''.<br />
<br />
<br />
Open the '''terminal.'''<br />
<br />
|-<br />
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.095cm;padding-right:0.191cm;"| Type '''ipython3 '''and''' '''press''' Enter'''<br />
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.095cm;padding-right:0.191cm;"| Type '''ipython3 '''and press '''Enter.'''<br />
<br />
<br />
From here onwards, remember to press the '''Enter''' key after typing every command on the '''terminal'''.<br />
<br />
|-<br />
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.097cm;padding-right:0.191cm;"| Type, '''t = (1, 2.5, "hello", -4, "world", 1.24, 5) '''<br />
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.097cm;padding-right:0.191cm;"| Let's learn to create a '''tuple'''. <br />
<br />
Type, '''t '''''is equal to inside brackets''''' 1 '''''comma''''' 2.5 '''''comma''''' '''''inside double quotes '''''hello '''''comma''''' -4 '''''comma''''' '''''inside double quotes '''''world '''''comma''''' 1.24 '''''comma''''' 5'''<br />
<br />
|-<br />
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.097cm;padding-right:0.191cm;"| Type, '''t'''<br />
<br />
<br />
Highlight , and parentheses<br />
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.097cm;padding-right:0.191cm;"| Type, '''t'''<br />
<br />
It is similar to '''list''' except that '''parentheses''' are used instead of '''square''' '''brackets'''.<br />
<br />
At least one comma is mandatory for a tuple. <br />
<br />
The brackets are optional, but should be added for clarity.<br />
<br />
|-<br />
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.097cm;padding-right:0.191cm;"| '''<nowiki>t[3] </nowiki>'''<br />
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.097cm;padding-right:0.191cm;"| The items in the '''tuple''' can be accessed by their '''index''' '''positions'''. <br />
<br />
<br />
Type, '''t '''''inside square brackets '''''3'''<br />
<br />
|-<br />
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.097cm;padding-right:0.191cm;"| '''<nowiki>t[1:5:2] </nowiki>'''<br />
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.097cm;padding-right:0.191cm;"| Type, '''t '''''inside square brackets '''''1 '''''colon '''''5 '''''colon '''''2'''<br />
<br />
It prints the corresponding '''slice.''' <br />
<br />
|-<br />
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.097cm;padding-right:0.191cm;"| '''<nowiki>t[2] = "Hello" </nowiki>'''<br />
<br />
<br />
<br />
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.097cm;padding-right:0.191cm;"| Now we try to change an element in the '''tuple'''. <br />
<br />
<br />
Type, '''t '''''inside square brackets '''''2 '''''is equal to''''' '''''inside double quotes '''''Hello'''<br />
<br />
<br />
We can see that, it raises an error saying ''''tuple object does not support item assignment''''. <br />
<br />
<br />
It shows, elements of a tuple cannot be changed after it is created.''' '''<br />
<br />
<br />
This is called '''immutability. '''<br />
<br />
|-<br />
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.097cm;padding-right:0.191cm;"| '''for x in t:'''<br />

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.097cm;padding-right:0.191cm;"| We can iterate over tuples like '''lists'''.<br />
<br />
Type,<br />
<br />
'''for x in t '''''colon''<br />
<br />
'''print '''''inside brackets '''''x'''<br />
<br />
<br />
It prints each elements of the tuple''' t .'''<br />

<br />
Exercise 1<br />
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.097cm;padding-right:0.191cm;"| Let us look at a simple problem of '''swapping values'''. <br />
<br />
Given, '''a''''' is equal to''''' 5''' and '''b '''''is equal to''''' 7''', swap the values of '''a''' and '''b'''. <br />
<br />
|-<br />
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.097cm;padding-right:0.191cm;"| Switch terminal<br />
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.097cm;padding-right:0.191cm;"| Switch to the terminal for the solution <br />
<br />
|-<br />
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.097cm;padding-right:0.191cm;"| Type, <br />
<br />
'''a = 5'''<br />
<br />
'''b = 7'''<br />
<br />
<br />
'''a'''<br />
<br />
'''b'''<br />
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.097cm;padding-right:0.191cm;"| Type, <br />
<br />
'''a '''''is equal to''''' 5'''<br />
<br />
'''b '''''is equal to''''' 7'''<br />
<br />
<br />
Then type, '''a'''<br />
<br />
Type, '''b'''<br />
<br />
|-<br />
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.097cm;padding-right:0.191cm;"| Type, <br />
<br />
'''temp = a '''<br />
<br />
'''a = b'''<br />
<br />
'''b = temp'''<br />
<br />
'''a'''<br />
<br />
'''b'''<br />
<br />
<br />
Highlight the outputs<br />
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.097cm;padding-right:0.191cm;"| We now create a '''variable''' say, '''temp '''and '''swap''' the '''values''' using this '''variable.''' <br />
<br />
<br />
Type <br />
<br />
'''temp '''''is equal to''''' a '''<br />
<br />
'''a '''''is equal to''''' b'''<br />
<br />
'''b '''''is equal to''''' temp'''<br />
<br />
Then type, '''a'''<br />
<br />
Type, '''b'''<br />
<br />
We can see that the values are successfully swapped now.<br />
<br />
<br />
But this is the traditional approach.<br />
<br />
|-<br />
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.097cm;padding-right:0.191cm;"| Type, <br />
<br />
'''a = 5'''<br />
<br />
'''b = 7'''<br />
<br />
'''a, b = b, a'''<br />
<br />
<br />
'''a'''<br />
<br />
'''b'''<br />
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.097cm;padding-right:0.191cm;"| Now let us do it in the python way.''' '''<br />
<br />
<br />
Type<br />
<br />
'''a '''''is equal to''''' 5'''<br />
<br />
'''b '''''is equal to''''' 7'''<br />
<br />
'''a, b '''''is equal to''''' b, a'''<br />
<br />
<br />
Now we will check whether the values are swapped.<br />
<br />
Type, '''a'''<br />
<br />
Type, '''b'''<br />
<br />
We see that the '''values''' are '''swapped''' easily.<br />
<br />
|-<br />
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.097cm;padding-right:0.191cm;"| Type, <br />
<br />
'''a = 2.5 '''<br />
<br />
'''b = "hello"'''<br />
<br />
'''a, b = b, a'''<br />
<br />
<br />
'''a'''<br />
<br />
'''b'''<br />
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.097cm;padding-right:0.191cm;"| We can also do this for different datatypes.<br />
<br />
<br />
Type,<br />
<br />
'''a '''''is equal to''''' 2.5 '''<br />
<br />
'''b '''''is equal to inside double quotes''''' hello'''<br />
<br />
'''a, b '''''is equal to''''' b, a'''<br />
<br />
<br />
Now to check the values, type, '''a'''<br />
<br />
Type, '''b'''<br />
<br />
<nowiki><<PAUSE>></nowiki>''' '''<br />

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.097cm;padding-right:0.191cm;"| Highlight a, b = b, a <br />
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.097cm;padding-right:0.191cm;"| This is possible because of the '''immutability''' of '''tuples'''. <br />
<br />
<br />
This is called''' tuple packing''' and '''unpacking'''. <br />
<br />
<br />
When you type, '''a''' ''comma'' '''b''' ''is equal to'' '''b''' ''comma'' '''a''' <br />
<br />
<br />
First the values of '''b''' and '''a''' are '''packed''' into a '''tuple''' on the right side. Then it is '''unpacked''' into the '''variables''' '''a''' and '''b'''. <br />
<br />
|-<br />
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.097cm;padding-right:0.191cm;"| '''5,'''<br />
<br />
<br />
Highlight the output<br />
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.097cm;padding-right:0.191cm;"| Let us first see about '''tuple packing'''.<br />
<br />
Type, '''5 '''''comma''<br />
<br />
<br />
We can see a '''tuple''' with one '''element'''. <br />
<br />
|-<br />
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.097cm;padding-right:0.191cm;"| '''5, "hello", 2.5 '''<br />
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.097cm;padding-right:0.191cm;"| Type, '''5 '''''comma inside double quotes '''''hello '''''comma''''' 2.5 '''<br />
<br />
<br />
Now it is a '''tuple''' with three '''elements'''. <br />
<br />
<br />
When we type two or more '''elements''' separated by '''commas''', those '''elements''' are packed into a '''tuple'''. <br />
<br />
<br />
'''Immutability''' of '''tuples''' ensures that the '''values''' are not changed during the '''packing''' and '''unpacking'''. <br />

<br />
<br />
# Define a '''tuple''' containing two values as given below. The first value is integer 4 and the second value is float 2.5. <br />
# If we type, '''a''' ''is equal to''''' 5''' ''comma ''then what is the datatype of '''a'''? <br />
# If we type, '''a''' ''is equal to inside brackets '''''2''' ''comma '''''3a''' ''inside square brackets '''''0''' ''comma'' '''a''' ''inside square brackets '''''1''' ''is equal to inside brackets '''''3''' ''comma'' '''4'''What is the output?<br />

<br />
# A tuple is defined by enclosing parentheses around a sequence of items separated by commas. Hence, we write our tuple as, ''inside brackets ''4 ''comma'' 2.5<br />
# Since the given data is 5 followed by a comma, it is a '''tuple''' <br />
# The given operation will give a '''TypeError'''. Because '''tuples''' are '''immutable'''. <br />
