I've written this simple code, that is possible to find on my github profile (it simply downloads some twitter data and store in an excel file).

It is one of my first experiments of using OOP in python: the code works (does its tasks as intended) but maybe an OOP implementation is not explicitly needed in this case.

Can I show this code as part of my coder portfolio as it is, or need some adjustment?

This is the code:


from twitterHandler import Twitter_User
import pandas as pd
import threading

if __name__=='__main__':
    usersIDS = {'UserName1':1234,'UserName2':1234,
    threads = {}
    excel_writer = pd.ExcelWriter("Twitter User's Report.xlsx", engine='openpyxl')

    def get_data(user_id): #get best last tweets and store them in a excel file
        user = Twitter_User.Twitter_User(user_id,2000)
        best_tweets = user.most_liked_rt()
        best_tweets.to_excel(excel_writer, '{}'.format(user.name),index=False)

    for user_name,user_id in usersIDS.items():
            t = threading.Thread(target=get_data,args=(user_id,))
            threads[user_name] = t
            print('Starting to get data for: {}'.format(user_name))
        except Exception as e:
            print('Something wrong happens: ',e)

    for name,t in threads.items():
        print('Process for {} Stopped'.format(name))

I have spend a few moments with your project and I have a few things which should be improved (in my opinion ofc).

  1. Use pep8 as your code formatting tool. If somebody will be reviewing your code this will be the first thing which she/he notice. There is a lot of empty lines, wrong formating etc.
  2. Improve your README.md. Add more info to your project descriptin. Get some data from a Twitter user is not enough :) Add some description for your API, maybe try to add some badges for codecov etc.
  3. Hardcoded value - this is bad smell. Example:

usersIDS = {'UserName1':1234,'UserName2':1234, 'UserName3':1234,'UserName4':1234}

  1. Use logger - using print is good, but if you want to look more professional use logger ;) Also add more descriptive message
  2. Too broad exceptions I know - sometimes this is impossible, but it looks like in few places it can be improved. For example line 31 in main.py. This looks weird for me, and would check what exactly can be broken here.
  3. Remove code which is comment - please care what you show other people

  4. Add unit tests - This is very very important. Add some unit tests. The best thing would be use TDD to create your app (Knowing what is TDD is very important on job interview)

  5. Add more descriptive comments

  6. Naming of variables - I know - this is very very hard, but your should not use naming like h_tags.

Also: What is this:

h_tags = h_tags[h_tags["Hashtags"].map(len) != 0]

It looks like a bug. Even if this do what should do, then it looks very weird and in my opinion should be refactored for something more readable.

Also your constructor looks weird. Catching exceptions in constructor is kind of bad smell.
