    <p>I want to remove dots in acronyms but not in domain names in a python string. For example, I want the string</p> <pre><code>'a.b.c. test@test.com http://www.test.com' </code></pre> <p>to become</p> <pre><code>'abc test@test.com http://www.test.com' </code></pre> <p>The closest regex I made so far is</p> <pre><code>re.sub('(?:\s|\A).{1}\.',lambda s: s.group()[0:2], s) </code></pre> <p>which results to</p> <pre><code>'ab.c. test@test.com http://www.test.com' </code></pre> <p>It seems that for the above regex to work, I need to change the regex to</p> <pre><code>(?:\s|\A|\G).{1}\. </code></pre> <p>but there is no end of match marker (\G) in python.</p> <p>EDIT: As I have mentioned in my comment, the strings have no specific formatting. These strings contain informal human conversations and so may contain zero, one or several acronyms or domain names. A few errors is fine by me if it would save me from coding a "real" parser.</p>

    1. COIMHO a regex is not the right tool for your problem. It might be possible but leads to overly complex code. I would employ a more traditional approach and use a mix regexs and python code to split the string into its components (normal text, acronyms, ...) and process the parts indivually. More verbose but also more maintainable.

    2. COI probably should have mentioned that I'm using this as part of a series of other regex's to normalize a sequence of strings representing informal human conversations. I can tolerate a few errors if that would save me from doing a more thorough parsing.

    3. COYou need to specify the problem better. Is your data always in three space separated parts, and you only want to affect the first part? Or do you need to apply this to arbitrary text? If the later, how would you define an acronym? Only single letters? If so, what do you expect to happen with http://a.b.example.com? Or is it that you want to remove embedded periods except when you know it is part of a domain name? But that only begs the question: When is it part of a domain name: After @ or http://? What about ssh: or other URL schemes? Once defined, any of these would be an easy regex.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
