Input Numbers Release For Free

If you write just input(), your input will be a string. That is why you have to write int(input()). If you write int(input()) then your input will be an integer.

In Python, you handle exceptions in a try ? except block. By wrapping the try ? except block inside a while loop, you can guarantee that only integers will make it through.

If you are using Python 2, you can use the `raw_input()` function to take integer input from the user. The `raw_input()` function reads a line of text from the user and returns it as a string. To convert this string to an integer, you can use the `int()` function.

If it needs to accept both integers and floats as inputs, then you should convert to float since floats can represent the integers. But if you're program requires that the input be specifically an integer, then you should be casting to int .

The int and float data types The int data type is used to store integers, while the float data type is used to store non-integral floating point numbers. If you store an integer value in a variable, Python will automatically use the int data type for that quantity.

With int(input()) you're casting the return value of the input() function call to an integer. With input(int()) you're using int() as a prompt for the user input. Since you don't pass int() an argument, it returns zero.

Reading Inputs as Numbers integer = int(input("Enter an integer as input: ")) print(integer*10) print(type(integer)) num = float(input("Enter an number as input: ")) sq = num*num print(sq) print(type(num)) num = float(input("Enter an number as input: ")) sq = num*num print(sq) print(type(num))
