def Division(a, b):
    print(a/b)
Division(3,4)
Division(3.0,4.0)
Division(3,4.0)
Division(3.0,4)

Notice that the function does not specify the types of the arguments, like you would see in statically typed languages. This is both useful and dangerous. For example:

def Division(a, b):
    print(a/b)
Division(2,"2")

In a statically typed language, the programmer would have specified the type of a and b (float, int, etc.) and the compiler would have complained about the function being passed a variable of the wrong type. This does not happen here, but we can use the try/except construction.

def Division(a, b):
    try:
        print(a/b)
    except:
        if b == 0:
           print("cannot divide by zero")
        else:
           print(float(a)/float(b))
Division(2,"2")
Division(2,0)
