In Python 3.x, raw_input was renamed to input and the Python 2.x input was removed. Theory; Steps; Problems; 1. But if we want to code in a single line and also want to give input in a single line then go for split() method. We need not write the code for factorial functionality rather directly use the math.factorial(). That also takes care of negative numbers and fractional numbers scenario. 1. x=input().split() print(x) After the execution of above code, user can supply space separated input as follows. In this article, we've created some programs in Python, to find and print average of n numbers entered by user at run-time. In Python, to provide multiple values from user, we can use − input() method: where the user can enter multiple values in one line, like − >>> x, y, z = input(), input(), input() 40 30 10 >>> x '40' >>> y '30' >>> z '10' For Python 2, the function raw_input() is used to get string input from the user via the command line, while the input() function returns will actually evaluate the input string and try to run it as Python code.In Python 3, raw_input() function has been deprecated and replaced by the input() function and is used to obtain a user's string through the keyboard. Is it possible to store them in an array? Many times we need to take multiline user input in Python whether if it’s for data analysis or data entry for automation. Python Input.

We can also use input function twice so that we can create a list of lists. Python provides two built-in functions for taking inputs from users: input raw_input In Python 3.6, the input function is used to take input from users, whereas, in Python 2.7, the raw_input function is used to take input from users. Python 2.7 uses the raw_input() method. When used, it enables the programmer to accept either a string, integer or even a character as an input from the user. The sum of the n natural number mathematical formula is = n * (n+1) / 2. Take a input from user in your python program using. And, decrement n number by 1 in while loop body. Formatted String Output. I am pretty sure this should work : my_input=raw_input() while(len(my_input)>0): #Do whatever you want my_input=raw_input() #take next input How to read and write in Python .
