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

Example: 

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]

Get a list as input from user in Python using Loop

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())
    # adding the element
    lst.append(ele) 
 
print(lst)
 






                        










Output: 


Python | Get a list as input from user


 


Time Complexity: O(n), where n is the length of the list 
Auxiliary Space: O(n) additional space of size n is created where n is the number of elements in the list

Get User Input in Loop using Python

                
In Python, for and while loops are used to iterate over a sequence of elements or to execute a block of code repeatedly. When it comes to user input, these loops can be used to prompt the user for input and process the input based on certain conditions. In this article, we will explore how to use for and while loops for user input in Python. User I

Take Matrix input from user in Python

                
Matrix is nothing but a rectangular arrangement of data or numbers. In other words, it is a rectangular array of data or numbers. The horizontal entries in a matrix are called as 'rows' while the vertical entries are called as 'columns'. If a matrix has r number of rows and c number of columns then the order of matrix is given by r x c. Each entrie

How To Add User Input To A Dictionary In Python

They provide a way to store and retrieve data efficiently based on keys. Dictionaries in Python are defined using curly braces {}.

It is important how keys are key for understanding PySimpleGUI elements. If the user does not specify a key, then the element will be called an input element, a key will be provided to the user by default in integer form, starting the numbering with zero. If the user doesn't specify any keys, then the values returned will be returned as a list as t
