Basic Bar Graph

#Example 1
def bar_graph():
    number_bank = []
    number = int(raw_input("Enter number here: "))
    for numbers in str(number):
        number_bank.append(int(numbers))
    if len(number_bank) < 10:
        for tokens in number_bank:
            print tokens, tokens * '*'
    else:
        print "Invalid! Max limit 9 digits only!"

#Example 2
a=raw_input("Enter number ")
if len(a) <= 9:
    for i in range(len(a)):
        print '*' * int(a[i])
else:
    print 'Number Exceeds should not be more then 9 '
