How do you write a program to input an integer?
The safest way is to capture the input as a string and then convert the string to an integer. The reason is that all standard input (regardless of where it comes from) is done through character streams and it's safer to capture this input using a string rather than trying to perform conversions on the incoming data directly.
How do you enter integer in python?
In Python, you can enter an integer using the input() function, which captures user input as a string. To convert this string to an integer, you can use the int() function. For example: user_input = input("Enter an integer: ") integer_value = int(user_input) This will convert the input string to an integer, assuming the user enters a valid integer.
