Question

Is there a codec in python that will escape everything that is not in the ascii range of 48-57 or 65-122 (i.e. not a alpha-numeric)

The only exception would be a slash and backslash characters.

Ideally, I would want to convert something like this:

/MyString/My#^/Blah/

To this:

/MyString/My\x23\x5e/Blah/

I know that there is the string-escape encoding which does something similar, but I need a custom range of characters to be encoded. I’m looking for clever suggestions or modules that can do this efficiently.

Thanks!

You can use re.sub with a function parameter like this:

s = "/MyString/My#^/Blah/"
import re
print re.sub(r'[^\w/\\]', lambda m: '\\x%x' % ord(m.group(0)), s)
#/MyString/My\x23\x5e/Blah/
