python - Search for text between 2 strings multiple times on the same line -

i have run little bit of trouble need search text between different strings. pulling url pasted in 1 line.

what searching multiple ips in document (which on same line). full strings in search this:

"ip_str": "0.0.0.0"} 

so find text between "ip_str": " , "}

also possible save of them output text document?

sounds away string splitting:

data = open('input.txt').read() fout = open('output.txt', 'w') parts = data.split('"ip_str": "') part in parts[1:]:     part_cleaned = part.split('"}')[0]     fout.write(part_cleaned + '\n') 

it's quick-and-dirty if write , run once think it's enough. using python's json module cleaner.
