Thread: how can I let the user input the word 'help' in my program??

Hello all,
I am new in programming and I am teaching myself through tutorials and youtube videos. I am making a program in which the user inputs numbers 0-5. each number calls a function and run specific operations that relate to that function. I want to add a function where if the user enters the word "help" rather than a number, that the program will print help documentation out on the screen. My problem is, since the input the user puts in is an int ((meaning the program is expecting an input from the user of an int from 0-5, calling that variable num_input)), how do I make an exception to where if the user enters the word ''help" that the program will not throw an error because it is expecting a number.

For example: what my program does now is:

Enter a number: 1
Enter a number : 17
Enter a 2nd number: 5
17 % 5 is 2

enter a number: 4
Type a fahrenheit temperature: 32
The centigrade equivalent of 32 is 0.0

I want the program to do this:
Enter a number: help

((print out some help documentation))

The input is already read in as an integer. do you mean to read all inputs of numbers as strings as well?
