I'll asume that by "find out if the number of a variable
is a natural number or not" you are asking how to determine whether the 
number a varible is set to is a Natural Number (ie in the set of  whole 
positive numbers; a positive integer).

If this is the case here we go:

def natural(x):
        if x >= 1 & x % 1 == 0:
                print "Varible is set to a NATURAL"
        else:
                print "Varible is NOT set to a natural"

run this lil snippet with the name of your varible as arg x
