Methodology / Instructions

Check Python version:
- Open terminal.
- Type python3 or python.
- Use print("Hello") to test.
Declare variables:
- Assign values directly, e.g., a = 10, b = "string".
- Use type(a) to check variable type.
Clear terminal:
- Press Ctrl + L.
Write and run Python script:
- Open text editor.
- Write code, e.g., print("Hello World").
- Save as script.py.
- Run with python3 script.py.
Work with lists:
- Declare: my_list = [1, 2, 3].
- Access element: my_list[0].
- Add element: my_list.append(4).
Work with dictionaries:
- Declare: my_dict = {'key1': 'value1'}.
- Access: my_dict['key1'].
- Add: my_dict['key2'] = 'value2'.
Import and use libraries:
- Import: import requests.
- Make GET request: response = requests.get('http://example.com').
- Print response: print(response.text).
Install packages:
- Use terminal: sudo apt install python3-pip.
- Install package: pip3 install flask.
Exit interpreter:
- Press Ctrl + D.
