Tuple shares some similarities to list.
Just like a list, a tuple variable can hold multiple values.

However:

There are no square brackets [ ].
The values are separated by a , .
It is good practice to use brackets ( ) around the values, but it is not required. However, where python can’t understand whether to evaluate the values as a tuple or a list, brackets will be required.

Creating new tuple.


<span>a_tuple</span> <span>=</span> <span>"</span><span>Rishi</span><span>"</span><span>,</span> <span>"</span><span>Abee</span><span>"</span>
<span>another_tuple</span> <span>=</span> <span>(</span><span>1</span><span>,</span> <span>2</span><span>)</span>
<span>a_tuple</span> <span>=</span> <span>"</span><span>Rishi</span><span>"</span><span>,</span> <span>"</span><span>Abee</span><span>"</span>
<span>another_tuple</span> <span>=</span> <span>(</span><span>1</span><span>,</span> <span>2</span><span>)</span>
a_tuple = "Rishi", "Abee"
another_tuple = (1, 2)

️ NOTE: Leaving a trailing , at the end of a value will cause python to evaluate the variable as a tuple instead.


<span>a_string</span> <span>=</span> <span>"</span><span>Rishi</span><span>"</span>
<span>a_short_string_tuple</span> <span>=</span> <span>"</span><span>Rishi</span><span>"</span><span>,</span>
<span>a_short_number_tuple</span> <span>=</span> <span>2</span><span>,</span>
<span>a_string</span> <span>=</span> <span>"</span><span>Rishi</span><span>"</span>
<span>a_short_string_tuple</span> <span>=</span> <span>"</span><span>Rishi</span><span>"</span><span>,</span>
<span>a_short_number_tuple</span> <span>=</span> <span>2</span><span>,</span>
a_string = "Rishi"
a_short_string_tuple = "Rishi",
a_short_number_tuple = 2,

Tuples can be added to a list.
To help python better understand whether to evaluate the values as a tuple, brackets ( ) are required.


<span>a_list</span> <span>=</span> <span>[</span><span>"</span><span>Orange</span><span>"</span><span>,</span> <span>"</span><span>Yellow</span><span>"</span><span>]</span>
<span>a_tuple_inside_a_list</span><span>=</span> <span>[(</span><span>'</span><span></span><span>'</span><span>,</span> <span>'</span><span></span><span>'</span><span>),</span> <span>another_tuple</span><span>,</span> <span>'</span><span>Hello</span><span>'</span><span>]</span>
<span>a_list</span> <span>=</span> <span>[</span><span>"</span><span>Orange</span><span>"</span><span>,</span> <span>"</span><span>Yellow</span><span>"</span><span>]</span>
<span>a_tuple_inside_a_list</span><span>=</span> <span>[(</span><span>'</span><span></span><span>'</span><span>,</span> <span>'</span><span></span><span>'</span><span>),</span> <span>another_tuple</span><span>,</span> <span>'</span><span>Hello</span><span>'</span><span>]</span>
a_list = ["Orange", "Yellow"]
a_tuple_inside_a_list= [('', ''), another_tuple, 'Hello']

A Tuple is Immutable

Unlike a list, a tuple cannot be modified by appending values to it.
If we need to add values to a tuple, we will have to re-assign the same tuple a new value.
