Modifying tuple contents with list in Python

When it is required to modify the list of tuple, the 'zip' method and the list comprehension can be used.

The zip method takes iterables, aggregates them into a tuple, and returns it as the result.

The list comprehension is a shorthand to iterate through the list and perform operations on it.

A list can be used to store heterogeneous values (i.e data of any data type like integer, floating point, strings, and so on). A list of tuple basically contains tuples enclosed in a list.

Below is a demonstration for the same −

Example

Live Demo

my_list_1 = [('Hi', 1), ('there', 2), ('Jane', 3)]
my_list_2 = [45, 67, 21]

print("The first list is : ")
print(my_list_1)
print("The second list is : " )
print(my_list_2)

my_result = [(i[0], j) for i, j in zip(my_list_1, my_list_2)]

print("The modified list of tuple is : ")
print(my_result)

Output

The first list is :
[('Hi', 1), ('there', 2), ('Jane', 3)]
The second list is :
[45, 67, 21]
The modified list of tuple is :
[('Hi', 45), ('there', 67), ('Jane', 21)]

Explanation

• A list of tuple is defined, and is displayed on the console.
• Another list is defined, and is displayed on the console.
• Both these lists are zipped, and iterated over.
• It is then converted to a list.
• This operation's data is stored in a variable.
• This variable is the output that is displayed on the console.
