Python Worksheet

Multiple-choice theory questions and predict-the-output code, plus short programs to write.

About This Worksheet

Try each question without running code first. For the programs, write them yourself, then compare with the answer and run your version in an editor or an example box above.

Section A — Theory

Practice

Multiple choice

Try each one on paper.

1.
$Which is a valid identifier? (a) 2total (b) total_2 (c) total-2 (d) for$
2.
$What data type is 3.0? (a) int (b) float (c) str (d) bool$
3.
$What does 22 % 5 give? (a) 4 (b) 4.4 (c) 2 (d) 17$
4.
$What does 22 // 5 give? (a) 4 (b) 4.4 (c) 2 (d) 5$
5.
$Which flowchart symbol matches input()? (a) diamond (b) rectangle (c) parallelogram (d) oval$
6.
$print("Total" + 5) causes which error? (a) SyntaxError (b) TypeError (c) NameError (d) none$
7.
$Using a variable that was never created causes which error in Python? (a) NameError (b) ValueError (c) ZeroDivisionError (d) IndentationError$
8.
$Which operator means 'not equal to'? (a) =! (b) <> (c) != (d) ==$
9.
$What type does input() return? (a) int (b) float (c) str (d) bool$
10.
$What is the value of 2 + 3 * 2 ** 2? (a) 14 (b) 20 (c) 100 (d) 36$

Section B — Predict the Output

Run to check Section BPython

1x = 52x += 33x *= 24print(x)5for i in range(2, 9, 3):6    print(i)7n = 18while n < 20:9    n = n * 310print(n)11def square(n):12    return n * n13print(square(3) + square(4))
