How would I best turn this string:
'2005-01-24 00:00:00.0'
into this string:
'2005%2D01%2D24%2000%3A00%3A00%2E0'
In order to call a URL.
urllib.quote_plus() is intended for this purpose though it doesn't have the result you ask for: >>> import urllib >>> s='2005-01-24 00:00:00.0' >>> urllib.quote_plus(s) '2005-01-24+00%3A00%3A00.0'
Are you sure you need to escape the - and . ?
You can get exactly what you want with a regular expression and the sub() method. One of the cool features of re.sub() is that the replace parameter can be a *function*. The function receives the match object and returns the replacement string. This makes it easy to define replacements that are programmatically derived from the original string:
>>> import re >>> def hexify(match): ... return '%%%X' % ord(match.group(0)) ...
hexify is the callback function, it will get a single character match and turn it into a hex string
>>> lett_num = re.compile('[^a-zA-Z0-9]')lett_num is a regular expression that matches everything except letters and digits.
>>> lett_num.sub(hexify, s) '2005%2D01%2D24%2000%3A00%3A00%2E0'

I've hunted through the standard library, but nothing seemed to jump out.
