Python Package Index atau PyPI dan Virtual Environment

Python Package Index atau PyPI merupakan repository dari pemrograman Python. PyPI akan membantu kita dalam mendapatkan dan menginsal aplikasi yang dibuat dan dibagikan oleh komunitas Python.

Pada artikel kali ini kita akan membuat virtual environment dan menginstal aplikasi tersebut pada virtual environment.

Python Package Index atau PyPI dan virtual environment adalah seperti pada contoh-contoh berikut ini

1. Mengecek versi Python

   C:\Users\Lenovo>python --version
   Python 3.8.2
   

2. Mengecek versi modul pip

   C:\Users\Lenovo>python -m pip --version
   pip 19.2.3 from C:\Program Files\Python38\lib\site-packages\pip (python 3.8)
   

3. Membuat virtual environment

   C:\WINDOWS\system32>python -m venv env01
   

4. Mengaktifkan virtual environment

   C:\WINDOWS\system32>env01\Scripts\activate
   
   (env01) C:\WINDOWS\system32>
   

5. Melihat daftar modul yang sudah diinstal pada virtual environment

   (env01) C:\WINDOWS\system32>python -m pip list
   Package    Version
   ---------- -------
   pip        19.2.3
   setuptools 41.2.0
   WARNING: You are using pip version 19.2.3, however version 23.2.1 is available.
   You should consider upgrading via the 'python -m pip install --upgrade pip' command.
   

6. Menginstal modul pada virtual environment
