problem with zfill

Hi,

I've strange problem with using zfill in python scripts in Zope.

My script is simple:
--------------
import string
outa = str1.zfill(6)
return outa
--------------

str1 is a parameter given by interface.

Running the script gives me:

Error Type: AttributeError
Error Value: 'str' object has no attribute 'zfill'

I understand the meaning of the error but why it's happening?

Others functions like:
outa = str1.upper()
works great.

Zope is in version 2.6.1 and Python in 2.2.1.

Regards,

try

return string.zfill(outa,6)

It's no use. Same error. Beside in my example "outa" was intended to be an
output string adn "str1" an input one. So if zfill() is the method for string
type (same as upper()) the form: "11".zfill(5) should give "00011". But it
still gives an error.

"11".zfill(5) should give "00011". But it still gives an error.

The zfill method wasn't added to str types until python 2.2.2b1.

zfill does not appear to be string method for the new syle (Python 2.X)
strings. It is in the string module and so is accessed by

import string
string.zfill(string, width)

In this case, zfill('11',5) produces '00011'.

This works for me in a Python Script with Zope 2.5.1 and Python 2.1.3.
