Python Programming Quiz – 30 Questions with Detailed Explanations

The article gathers thirty Python quiz questions inspired by the wtfpython project and other sources, aiming to help readers sharpen their Python skills.

Each question is presented with an image of the original multiple‑choice prompt, followed by the answer (e.g., A, B, C, or D) and a concise explanation of why that choice is correct.

Key topics covered include:

Operator precedence and the use of the walrus operator ( (x := [1, 2]) ).

Iteration behavior when modifying a list during a loop, demonstrating how elements are skipped or removed.

Differences between == and is , object identity, and integer caching.

Exception handling scopes, showing how except E as N creates a temporary name that is deleted after the block.

Generator expressions and the effect of the yield from syntax introduced in Python 3.3.

Scope modifiers global and nonlocal , illustrating how variables are resolved in nested functions.

String methods such as strip , rstrip , and the newer removesuffix / removeprefix introduced in Python 3.9.

Dataclasses inheritance rules and the impact of default field values.

Function signature restrictions using positional‑only ( / ) and keyword‑only ( * ) parameters introduced in Python 3.8.

Code examples are shown in their original form, wrapped in ... tags to preserve exact syntax, for instance:

<code>score -= (-1)</code>

<code>In : isinstance(True, int)
Out: True</code>

<code>def a():
    yield 1

b = (x for x in [1, 8, 15] if [2, 8, 22].count(x) > 0)</code>

The article concludes with a promotional section offering free Python learning resources, but the primary value lies in the comprehensive set of quiz questions and their explanatory answers, making it a useful study aid for Python developers.
