Both Python2.x and Python3.x Set in Python is a data structure equivalent to sets in mathematics. Set elements are unique. You need to use raw_input in python 2.x and input in Python 3.x. Taking Integer Input in Python. A problem statement at the end of each tutorial will assess your understanding. Example Learn about different variable types and type-casting so you can effectively work with strings and numbers from the user. How the input function works in Python : raw_input ( ) : This function works in older version (like Python 2.x). Let’s see what all that means, and how you can work with sets in Python. Sets can be used to carry out mathematical set operations like union, intersection, difference and symmetric difference. In Python 3.x, raw_input was renamed to input and the Python 2.x input was removed. Python allows for user input. User Input. To do so you can use the input() function: e.g. In python 3: raw_input() function was renamed to input() and it always returns the type as string. So the input is just a set of strings with predefined format that fed into standard input.Suppose, for example, a problem requires us to read in N stacks of different sizes.
