Hello everyone,
I just wanted to know how I can check if a string input is a number?

You can try to convert the str into an int or float and catch the exception if it fails.

Hello,
there are several ways. There are plenty of explanations available if you search online. You can also start with this tutorial on our forums:

As the above post said, there are several ways, one of which is to use the variable.is_integer()

var=input("Enter a value")
if var.isint() == True:
    return True
else:
    return False

Did you look through the docs for str , i.e. the list of methods?
