Pipenv Understanding

Day 1

• pipenv install to create workspace and install dependencies

• pipenv shell to activate the virtual env

• Once the shell is activated, run python hello.py to bring the Flask App UP!!

• By default the flash app runs on port 5000 - http://localhost:5000/hello

• pipenv install fpdf - install the fpdf module which is used to create the pdf

• Acticate the shell again to execute python pdf_create.py which will create example.pdf

• pipenv install PyPDF2 - install the PyPDF2 module which is used to read the pdf content

• Acticate the shell again to execute python pdf_Reader.py which will read the contents of example.pdf

• basics.py contains all the basic syntaxes in python

• modules.py - python searches the list of directories from sys.path. Use sys.path.append(directory_path) to add directory searches during import.

    python3
    >>> import sys
    >>> sys.path
    ['', '/usr/local/Cellar/python/3.7.5/Frameworks/Python.framework/Versions/3.7/lib/python37.zip', '/usr/local/Cellar/python/3.7.5/Frameworks/Python.framework/Versions/3.7/lib/python3.7', '/usr/local/Cellar/python/3.7.5/Frameworks/Python.framework/Versions/3.7/lib/python3.7/lib-dynload', '/usr/local/lib/python3.7/site-packages']

  • Alternatively use PYTHONPATH to set the package/module import paths.
    • If a package has __init__.py, it becomes a module
    • learn is a module which is used in modules.py
