0.1 · Recall

1. What characterizes Python among languages?

A compiled language reserved for experts An interpreted, readable, versatile language A language only for the web A code editor like VS Code

Python runs line by line with no compilation and its clear syntax makes it an excellent first language.

0.1 · Application

2. Nabil wants to automate his reports and analyze his sales in Algiers. What should he do at level 0?

Skip the basics and directly import advanced packages Rewrite his own packages instead of using the ecosystem Learn everything at once: web, data, AI and automation Choose his 2 priorities (data + automation) and keep the basics as priority

The basics are shared; specialization comes at level 4, guided by a measurable goal.

0.1 · Application

3. Facing a classic need (analyzing a spreadsheet), which reflex does the ecosystem recommend to Nabil?

Reinvent a full analyzer by hand First look for the existing, tested package, then assemble it Switch language for each need Wait for level 4 without practicing anything

Python's strength is assembling tested packages rather than reinventing.

0.1 · Arbitration

4. Nabil is told that "easy to read" Python is not a serious language. What verdict?

Accept it if only targeting the web Refuse it because Python is compiled Accept it: readability proves weakness Refuse it: readability is a professional strength and the ecosystem is robust

Seriousness lives in the proven ecosystem and maintainability, not in punctuation.

0.2 · Recall

5. What makes up a ready Python workstation?

The Python interpreter + an editor like VS Code, verified An antivirus and a printer A production server only A single HTML file opened with a double-click

The interpreter runs, the editor writes: both verified by the trio.

0.2 · Application

6. Nabil types "python" and the terminal answers "not recognized". What to do first?

Rerun the installer in Modify mode to check "Add Python to PATH" Remove VS Code Install an antivirus Only switch editor

Without PATH, the system cannot find the command: it is trap #1 on Windows.

0.2 · Application

7. Nabil just installed VS Code. Which move guarantees the right Python runs his code?

Stack installations to compare Open any folder without checking Explicitly select the interpreter in VS Code then run test.py Code the whole project before any test

It is the selected interpreter that runs, not the editor.

0.2 · Arbitration

8. Nabil has two Python installations getting mixed up. What verdict?

Continue: the more, the better Clean up: keep one clean official installation then replay the trio Code everything in the REPL to dodge the issue Also install version 2

One clean installation + verification trio avoids mixing.

0.3 · Recall

9. REPL and .py file: what is the difference?

The REPL compiles to binary, the .py hosts websites There is no practical difference Both keep programs the same way The REPL tests in 5 seconds without saving; the .py keeps a real program

REPL to explore, file to build: the two everyday moves.

0.3 · Application

10. Nabil runs print(Hello) without quotes and gets NameError. What to fix?

Reinstall Python and VS Code Switch operating system Add quotes: print("Hello") — it is text, not a variable Remove all prints from the file

Without quotes, Python looks for a Hello variable that does not exist.

0.3 · Application

11. Nabil wants to display his total with his first name cleanly. What to choose?

A fragile concatenation with manual conversions A loop installing packages An f-string: print(f"Hello {prenom}: {total} sales") A comment instead of the display

The f-string inserts variables readably, with no manual conversion.

0.3 · Arbitration

12. Facing a long red traceback, Nabil wants to fix everything at random. What verdict?

First read the last line (the error), then locate and fix Delete the file and restart everything on each error Code the rest in the REPL to forget the error Continue: fixing at random always ends up working

The last line names the error, the top locates it: read before fixing.

What's next?

Score ≥ 80%: move to Level 1 — variables, conditions, loops and functions with Nabil.
Score between 50% and 80%: review the failed section(s) (0.1 paths, 0.2 workstation, 0.3 first program), reread the explanations above, then retake the test.
Score < 50%: reread all of level 0, applying each 48h challenge (written path, executed test.py, hello.py with f-string) before retrying.
And next? Keep your Nabil hello.py: level 1 enriches it with variables, inputs and calculations.
