Python's method for counting the number of uuids in a file after de-duplication.

This article example describes how Python counts the number of uuids in a file after de-duplication. Shared for your reference. Specific as follows:

Get the uuids in the log file by line using regular expressions and count the number of de-duplicates of these uuids (de-duplicates using set).

import re
pattern=(r'&uuid=.*&')
uuidset=set()
with open('.2015-05-26','rt') as f:
    for line in f:
        all=(line)
        if len(all)>0 and ('iphone')>0:
            # print(all[0])
            (all[0])
print(len(uuidset))

I hope that what I have described in this article will help you in your Python programming.
