Let’s see how to accept float value from a user in Python. The entered string will simply be submitted to the application. Each replacement field contains either the numeric index of a positional argument present in the format method or the name of a keyword argument. Let’s see how to use str.rjust(),   str.ljust() and str.center() to justify text output on screen and console. The raw_input() and input() are two built-in function available in python for taking input from the user. 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. The input() function works with python 3.x version. We have already seen the print function in Python, which sends data to the console. This website uses cookies to ensure you get the best experience on our website. Let others know about it. The value stored in the variable when taking the input from the user will be of type string. This function takes two parameters: the initial string and the optional base to represent the data. Read How to check if user input is a number or String. In each iteration, we can get input string from the user and then .join() them using \n, or you can also concatenate each input string using + operator separated by \n. Then the input() function reads the value entered by the user. As you might know, raw_input always returns a String object and same is the case with input in Python 3.x To fix the problem, you need to explicitly make those inputs into integers by putting them in int () function. Well organized and easy to understand Web building tutorials with lots of examples of how to use HTML, CSS, JavaScript, SQL, PHP, Python, Bootstrap, Java and XML. I have a short assignment to write a python function that takes a user input string (one character) to represent a math function and a user input integer to represent a numerical value to process in that function. As you know whatever you enter as input, the input() function always converts it into a string. Similarly, take a look at an example of input function in Python 3. Define a function, which is used to convert string into array using for loop. i.e., In Python, we can accept two or three values from the user in one input() call. 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. You can display output in various styles and formats using the following functions. For example, accept a list of numbers from the user. Use the syntax print(int("STR")) to return the str as an int, or integer. Use
 tag for posting code. Like string and integer, we can also accept list and array as an input from a user. All the best for your future Python endeavors!
