How to Setup Virtual Environment in Python with venv



  • A virtual environment is the most used tool by the developers to isolate the dependencies for different projects.
  • Suppose you have two projects say porj1 and proj2. proj1 needs the Django dependency with version 3.2 but your proj2 needs the Django dependency with version 2.2. In this situation you need a virtual environment to keep the both version on your system separately. 

How to create virtual environment in python:

  1.  Decide a directory where you want to create the virtual environment. You can use your project directory or any other directory as per your wish.
  2.  Run the below command. Here`awesome_proj_env` is the folder where virtual environment will be created. if the folder does not exists then it will be created automatically.
    • python3 -m venv awesome_proj_env   
  3. Activate the virtual environment:
    1. On Linux/Mac OSX:
      • source awesome_proj_env/bin/activate 
    2. On Windows:
      • awesome_proj_env\Scripts\activate.bat
  4. Deactivate the virtual environment in Python: type "deactivate" on terminal to deactivate the current selected virtual environment.

Simple way to import and export collections in MongoDB

  A simple command will help to import and export collections in mongoDB. Export/Dump Collections in MongoDB: mongodump -d <database_name> -o <directory_backup> The above command will dump all the collections in the defined directory. eg: if your database name is awesome_db and you selected the my_db_backup as backup directory then you need run below command: mongodump -d awesome_db  -o my_db_backup If your db has authentication enabled then pass -u <username> -p <press enter> with the above command. Import/Restore Collection in MongoDB: mongorestore -d <database_name> <directory_backup> Similarly this command will restore the collections in the mongodb database.  for eg: mongodump -d awesome_db -o my_db_backup pass the authentication -u <username> -p <press enter> if your mongodb has authentiction.
