Answer Key
Python · Modules 11–20 · Student wording will vary for definitions
1name = "Alice" — Assigns the string Alice to the variable name.
2f"Hello {name}" — f-string: put f before the quote and insert variables in {curly braces}.
3age = 15 — Assigns the integer 15 to the variable age.
4f"I am {age} years old" — f-string converts the number in age to text automatically.
5> — Greater than - checks if the left value is larger than the right.
6< — Less than - checks if the left value is smaller than the right.
7== — Equal to - checks if both values are the same.
8!= — Not equal to - checks if the two values are different.
9Boolean — A data type with only two values: True or False.
10and — Returns True only if BOTH sides are True.
11or — Returns True if at least ONE side is True.
12not — Flips the Boolean: True becomes False, False becomes True.
13if — Runs the indented code only when the condition is True.
14Condition — An expression that evaluates to True or False.
15Colon : — Required at the end of every if statement line.
16Indentation — Spaces (usually 4) that define what's inside the if block.
17elif — Short for 'else if' - checks another condition if the previous was False.
18Chaining — Using multiple elif blocks to check many conditions in order.
19First match wins — Only the first True condition in an if/elif chain runs.
20Condition order — Python checks if, then each elif, from top to bottom.
21else — Catch-all block that runs when all if/elif conditions are False. else never has a condition - just else: with a colon.
22if/else — Two-way decision where one path or the other always runs.
23if/elif/else — Multi-way decision with a fallback that runs when no condition matches.
24// — Floor division - divides and rounds DOWN to the nearest integer.
25% — Modulo - returns the remainder after division.
26** — Exponent - raises the left number to the power of the right.
27Remainder — What is left over after division, found using %.
28import — Keyword that loads a module so you can use its functions.
29Module — A file of pre-written Python code with reusable functions.
30random — Built-in module for generating random numbers and choices.
31time — Built-in module for time-related functions like sleep().
32while — Repeats indented code as long as the condition is True.
33Infinite loop — A loop that never ends because the condition stays True.
34Counter variable — A variable like i that tracks how many times the loop has run.
35for — Loop that iterates through each item in a sequence.
36in — Keyword that connects the loop variable to the sequence.
37Loop variable — Variable that takes each value from the sequence e.g. i or x.
38Sequence — What you loop over: a list, string, or range.
