Use an input() function with split() function to split an input string by space and splits a string into a list to create a list from user input in Python.

Example create a list from user input in Python

Simple example code gets a list of numbers as input from a user.

input_string = input('Enter elements separated by space: ')

user_list = input_string.split()

# print list
print('list: ', user_list)

Output:

Python creates a list from user input

Another example

Using for loop and range function.

listA = []
# Input number of elemetns
n = int(input("Enter number of elements in the list : "))

for i in range(0, n):
    print("Enter element No-{}: ".format(i + 1))
 
    listA.append(input())  # adding the element

print("The entered list is: \n", listA)

Output:

Enter number of elements in the list : 2
Enter element No-1:
A
Enter element No-2:
1
The entered list is:
[‘A’, ‘1’]

With map

User to enter the values continuously but separated by space. Here we use the map function together with the inputs into a list.

listA = []
# Input number of elemetns
n = int(input("List elements: "))

listA = list(map(int, input("Numbers : ").strip().split()))[:n]

print(listA)

Output:

List elements: 2
Numbers: 1 2
[1, 2]
