isinstance function in if statement python [duplicate]

Question

As part of a lcm program I'm creating, I want a condition to determine whether the result of an expression is integer or float. After looking online, I found the isinstance function, which outputs a boolean. I want to be able to use that in the statement, and execute the respective . How exactly do I code it? This is an example:

num=input("Enter a number: ")
if isinstance(num,int):
  print("Float")
else:
  print("Integer")

input will always return a str. What, exactly, are you trying to do here? — juanpa.arrivillaga

You need to go deeper =)

def int_of_float( n ) :
    try :
        num = int(num)
        return 'Integer'
    except ValueError :
        pass

    try :
        num = float(num)
        return 'Float'
    except ValueError :
        pass

    return 'Unknown'

num = input( 'need a number: ' )
print int_or_float( num )
