If a number starts with 0
, it is interpreted as octal, or base 8. Just do:
print 1
print 10
print 100
print 1000
And your problem will be solved.
More on octal: http://en.wikipedia.org/wiki/Octal
Here is a way to understand octal easier:
octal 1 is decimal (normal numbers) 1
octal 2 : decimal 2
…
octal 7 : decimal 7
octal 10: decimal 8
octal 11: decimal 9
octal 12: decimal 10
…
octal 17: decimal 15
octal 20: decimal 16
and so on. Octal just uses digits from 0 to 7.
Hope this helped!
