## Status Updates
As part of 21 days of lockdown, I started learning python from March 25th, 2020.
### Day 1
- `cd pipenv`
- `pipenv install` - Similar to `npm install`. Creates 2 files `Pipfile` and `Pipfile.lock` similar to `package-lock.json` in the javascript world with dependencies based on `requirements.txt`
- `pipenv shell` - Activates the virtual environment. Much simpler than `virtualenv`
- Once the shell is activated, run `python3 hello.py` to bring the Flask app UP!!
- By default the flask app runs on 5000 port - `http://localhost:5000/hello`
- `pipenv install PyPDF2` - installs the PyPDF2 package and updates `Pipfile` and `Pipfile.lock` files.
- Once the shell is activated, run `python3 pdf_reader.py` to read the `example.pdf` file
- `basics.py` - file which includes all 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.
```python
python3
Python 3.7.5 (default, Nov 1 2019, 02:16:32)
[Clang 11.0.0 (clang-1100.0.33.8)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> 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`
### Day 2
- cd `functions`
- Started using callable functions inside a class
### Day 3
- Started using Functions and String manipulation
### Day 4
- `cd tuples`
- Started using `tuples`
### Day 5
- `cd dictionaries`
- Started using `dictionaries`
- Started using `set`
### Day 6
- Started with class usage and best practices
### Day 7
- class methods
- static methods
### Day 8
- class equals and repr
- Data Class usage
### Day 10
- Files and Directories
### Day 12
- Lambda
### Day 13
- Solving LeetCode program - [Problem](https://leetcode.com/problems/two-sum/)
