Append int to list python

Python | Get a list as input from user

We often encounter a situation when we need to take number/string as input from the user. In this article, we will see how to get as input a list from the user.
Examples:

Input : n = 4, ele = 1 2 3 4 Output : [1, 2, 3, 4] Input : n = 6, ele = 3 4 1 7 9 6 Output : [3, 4, 1, 7, 9, 6]

Code #1: Basic example

Python3

# creating an empty list

lst = []
# number of elements as input

n = int(input("Enter number of elements : "))
# iterating till the range

for i in range(0, n):

ele = int(input())

lst.append(ele) # adding the element

print(lst)

Output:

Code #2: With handling exception

Python3

# try block to handle the exception

try:

my_list = []

while True:

my_list.append(int(input()))

# if the input is not-integer, just print the list

except:

print(my_list)

Output:

Code #3: Using map()

Python3

# number of elements

n = int(input("Enter number of elements : "))
# Below line read inputs from user using map() function 

a = list(map(int,input("\nEnter the numbers : ").strip().split()))[:n]

print("\nList is - ", a)

Output:

Code #4: List of lists as input

Python3

lst = [ ]

n = int(input("Enter number of elements : "))

for i in range(0, n):

ele = [input(), int(input())]

lst.append(ele)

print(lst)

Output:

Code #5: Using List Comprehension and Typecasting

Python3

# For list of integers

lst1 = []
# For list of strings/chars

lst2 = []

lst1 = [int(item) for item in input("Enter the list items : ").split()]

lst2 = [item for item in input("Enter the list items : ").split()]

print(lst1)

print(lst2)

Output:
