Comapring two files

[burningkrome]

As a suggestion, look into Python's "re" module (regex). Then you could match line by line from both files.

See here for more suggestions.

Also here for how to iterate through a file.

import re

s1 = "2019-10-03 text in the source file"
s2 = "2019-10-03 text from the file to be searched"

matches = re.search("^(\d{4}-\d{1,2}-\d{1,2})(.*)$", s1)
print(matches.group(1))

# Then use an if in
if matches.group(1) in s2:
    matches = re.search("^(\d{4}-\d{1,2}-\d{1,2})(.*)$", s2)
    print(matches.group(2))
