Python - how to test if a users input is a decimal number [duplicate]

Question

I am writing a program that needs to check if a users input is a decimal (the users input must be a deciamal number),I was wondering how I could test a varible to see if it contains only a decimal number.

Thanks, Jarvey

Answer 1

U also could use a Try/Except to check if the variable is an integer:

try:    
    val = int(userInput) 
except ValueError:    
    print("That's not an int!")

or a float:

try:    
    val = float(userInput) 
except ValueError:    
    print("That's not an float!")
