Regex Working On Regexpal But Not With Python

I am trying to write a regex to catch email Ids . Testing since quite a few hours using regexpal.com . On the site, its able to catch all the email Ids. WHen I am substituting the

Solution 1:

Read the documentation for re.findall:

If one or more groups are present in the pattern, return a list of groups

Your groups only capture the at sign, dot, etc., therefore that's all that's returned by re.findall. Either use non-capturing groups, wrap the whole thing in a group, or use re.finditer.

(As noted by @Igor Chubin, your regex is also incorrectly using . instead of \., but this isn't causing the main problem.)

Solution 2:

You must use \. not . here:

(.|dot)

If you just want to say that you can have hyphens between letters in the edu part, you can do this without slashes and grouping:

e-?d-?u-?[.,]?

If you use () just to group symbols (but not for capturing), you must use (?:)instead:

(?:@|at)
