python doesn't like my numbers

[paul k]

hi,

is there any way to convince python not to take my (phone)numbers
starting with zero as octals?
[color=blue][color=green][color=darkred]
>>> int(088)[/color][/color][/color]
File "<stdin>", line 1
int(088)
^
SyntaxError: invalid token

thanks
Paul

What is the integer value of a phone number?

Answer 1: Use strings: that's really what telephone numbers should be

Answer 2: Use valid octal digits in your phone numbers. The digit '8'
cannot appear in base 8 numbers, only the digits 0-7.

Why do they have to start with zeros in your source code?

The fact that you're passing the number through int() makes me guess
that you're actually talking about input of some kind which you'll pass
through int(). If that's the case, they will be strings, and the problem
will go away:
[color=blue][color=green][color=darkred]
>>> int('088')[/color][/color][/color]
88

I can't change reality (yet) ;)

My guess is that his program was simply using "input()"

Im rather new to python and I've to say that I found quite
surprising that the "input" function does also evaluate
(so entering "1+1" i get the number 2 and not the string
"1+1") and that I've to use "raw_input" to get what the
user typed in.
