Question

I am trying to write regular expression in python. Let’s say that I have a string

string = "alpha=23; beta=34; gamma=43"

I want to read this string and store the values of alpha, beta and gamma in a database. How can I write a regex that would do that.

My guess is that i have to look for regex that checks for words followed by = sign. I wrote this:

matchObj = re.search( r'\w+(?==)', string, re.I)

This outputs alpha and stops?

1. Is this correct?
2. How can i read all the values?

Answer 1

1
Yes it is correct, search stops after the first match.

2
try findall instead of search

It returns a list.

re.findall( r'(\w+)=([^;]+)', string, re.I)

If you want to use split:

[re.split('=',s) for s in re.split(';',string)]
