should help you out Don't use regex for this. Use the urlparse standard library instead. It's far more straightforward and easier to read/maintain.

Finding out names from Regular Expression using Python

By : Shayne Foo

To fix this issue I have to find or extract names like Aggarwal, Dr Rakesh Om and Aggarwal, Prof. Amita Rao and using regular expression in python from a web page. I am learning regular expression. , I think you need a regex like this:

code :

"[A-Za-z]+\s*,\s*(Dr\.?|Prof\.?) [A-Za-z ]+"

"[a-z]+\s*,\s*(Dr\.?|Prof\.?) [a-z ]+"gi

Python Regular Expression: Matching Car Speeds without Highway Names

By : KirstenR

Date : March 29 2020, 07:55 AM

wish helps you I'm trying to match speed descriptions of highway tickets, for example,text lines: , Description

code :

([0-9]+)(?:-([0-9]+)|\s*over)

'm trying to match speed descriptions of highway tickets, for example,text lines:

"L A 16-25MPH" should return 2 groups: 16, 25 
"LIMITED ACCESS SPEED I-75" should return no matches.
"LMT ACC 6-10" should return 2 groups: 6, 10 
"6 OVER" should return 1 group: 6

I'm OK with all of the above situations, but I run into issues for strings with numbers that aren't related to speed, for example:

"LIMITED ACCESS SPEED I-75" should return no matches.

MATCH 1
1.  [89-90] `16`
2.  [91-93] `25`

MATCH 2
1.  [193-194]   `6`
2.  [195-197]   `10`

MATCH 3
1.  [231-232]   `6`

Python Regular Expression to Identify City Names Out Of Strings

By : peng sheng

like below fixes the issue What you are after is not possible with regular expressions. Regular expressions need string patterns to work. In your case, it would seem that the pattern either does not exist or can take a myriad of forms.
What you could do would be to use a search efficient data structure and split your string in words. You would then go through each word and see if it is in your search efficient data structure.
