Python Foundations on the Pi

10 Lektionen in dieser Stufe

1. Running Python in Thonny and from the Terminal
   Start a Python program three ways and know when to use each. · Lab: Run the same two-line program in the Thonny shell, as a Thonny script and with python3 in the terminal.
2. Variables, Numbers and Strings
   Store values, do arithmetic and build text with f-strings. · Lab: Write a unit converter that turns Celsius into Fahrenheit and prints a formatted sentence.
3. Making Decisions with if, elif and else
   Branch a program on comparisons and combined conditions. · Lab: Classify a temperature as cold, comfortable or hot and handle the boundary values correctly.
4. Repeating Work with for and while Loops
   Repeat actions a fixed number of times or until a condition changes. · Lab: Print a countdown, then loop until the user types "stop".
5. Lists, Tuples and Dictionaries
   Group related values and look them up by position or by key. · Lab: Store five readings in a list, compute min, max and mean, and keep sensor names in a dictionary.
6. Writing and Calling Your Own Functions
   Package logic into functions with parameters and return values. · Lab: Refactor the converter and the statistics code into three reusable functions.
7. Reading and Writing Text Files in Python
   Open files safely with the with statement and write CSV rows. · Lab: Append a timestamped line to a CSV file each time the script runs and read the file back.
8. Handling Errors with try and except
   Read a traceback and keep a program running through expected failures. · Lab: Make the converter survive text input, a missing file and division by zero.
9. Importing Modules and Using the Standard Library
   Use time, datetime, pathlib, random and subprocess instead of rewriting them. · Lab: Read the CPU temperature from /sys with pathlib and time-stamp it with datetime.
10. Virtual Environments and pip on Bookworm
    Create a venv, install packages into it and explain the "externally managed" message. · Lab: Create a venv with --system-site-packages, install a package with pip and prove the system Python is untouched.

Abschlussprojekt

A command-line health reporter that reads CPU temperature, memory and disk use, appends them to a CSV file and prints a warning when a limit is crossed.
