Question 1 (Write a function that takes two arrays as input, each array contains a list of A-Z; Your program should return True if the 2nd array is a subset of 1st array, or False if not.)
def isSubset(arr1, arr2):
count = 0
flagSubset = False
for i in range(len(arr2)):
for j in range(len(arr1)):
if(arr2[i].strip().upper() == arr1[j].strip().upper()):
count+=1
break

How to push to multiple git remotes at once. Useful if you keep mirrors of your repo.

Pushing to Multiple Git Repos

If a project has to have multiple git repos (e.g. Bitbucket and Github) then it's better that they remain in sync.

Usually this would involve pushing each branch to each repo in turn, but actually Git allows pushing to multiple repos in one go.

If in doubt about what git is doing when you run these commands, just

richardoey / Delete Files when Deleting Models Django
Last active March 9, 2021 03:58
Django basically doesn't delete the associate file in the model you delete. In order to automatically delete all the file when model is delete, put below code inside the models.py.
from django.db.models.signals import post_delete, pre_save
from django.dispatch import receiver
from django.db import models
""" Whenever ANY model is deleted, if it has a file field on it, delete the associated file too"""
@receiver(post_delete)
def delete_files_when_row_deleted_from_db(sender, instance, **kwargs):
for field in sender._meta.concrete_fields:
if isinstance(field,models.FileField):
instance_file_field = getattr(instance,field.name)

Workflow working while waiting for pending PR

Preferred workflow for this:

  1. On branch master, git checkout -b user_story_1.
  2. Make changes to user_story_1.
  3. Open PR for user_story_1.
  4. On branch user_story_1, git checkout -b user_story_2.
  5. Make changes to user_story_2.
  6. Once user_story_1 gets merged into master, switch to user_story_2 and do git rebase -i master.
  7. This should show you a list of commits on user_story_2 that you want to include in the rebase. Delete the top few commits that came from user_story_1.
  8. The rebase should complete cleanly unless master was updated with other changes. Now you have user_story_2 rebased on master and only having its commits.
