Quick Questions
Shade in the A or B circle for each question.
1. Which Python line matches the pseudocode: Score ← 10
2. Which Python line matches the pseudocode: INPUT Name
3. Which Python line matches the pseudocode: OUTPUT Total
4. The pseudocode is INPUT Age and Age will be used in a sum. Which Python line is better?
5. The pseudocode is INPUT Price where Price can be 2.50. Which Python line is better?
B
Match the Pairs
Draw a line connecting each item on the left to its match on the right.
| Left column | Right column | |
|---|---|---|
| 1Age = int(input()) | APrice = float(input()) | |
| 2print(Name, Score) | BPython for INPUT Age: reads what the user types and turns the text into a whole number | |
| 3Python has no ← arrow, so the pseudocode Total ← 0 is written with a plain = sign | CAge is still text because int() was not used, so adding 1 to it causes an error. It should be Age = int(input()). | |
| 4To read a decimal number such as a price, wrap input() in float() so the text becomes a real number | DPython for OUTPUT Name, Score: shows both values on one line | |
| 5Age = input() Next = Age + 1 | EPseudocode was left unchanged: Python needs Total = 5 and print(Total) instead of the arrow and OUTPUT. | |
| 6Total ← 5 OUTPUT Total | FTotal = 0 |

Answer Key
Pseudocode assignment, INPUT and OUTPUT in Python
Section A: Quick Questions
Q1
A — Score = 10
Q2
A — Name = input()
Q3
A — print(Total)
Q4
B — Age = int(input())
Q5
B — Price = float(input())
Section B: Match the Pairs
Q1
Age = int(input()) → Python for INPUT Age: reads what the user types and turns the text into a whole number
Q2
print(Name, Score) → Python for OUTPUT Name, Score: shows both values on one line
Q3
Python has no ← arrow, so the pseudocode Total ← 0 is written with a plain = sign → Total = 0
Q4
To read a decimal number such as a price, wrap input() in float() so the text becomes a real number → Price = float(input())
Q5
Age = input()
Next = Age + 1 → Age is still text because int() was not used, so adding 1 to it causes an error. It should be Age = int(input()).
Q6
Total ← 5
OUTPUT Total → Pseudocode was left unchanged: Python needs Total = 5 and print(Total) instead of the arrow and OUTPUT.
Section C: Definitions
Q1
Age = int(input()) — Python for INPUT Age: = replaces the arrow, input() reads text, and int() turns that text into a whole number. OUTPUT Age becomes print(Age); use float() for decimals.Section D: Fill in the Blanks
Q1
Name = input()Q2
Age = int(input())Q3
Price = float(input())Q4
Total = 7 + 3
print("Total:", Total)Q5
Score = int(input())Section E: Spot the Error
Q1
B — input is a function, so it needs brackets to be called. INPUT Age becomes Age = int(input()), with input() ending in ().
Q2
B — The arrow ← is pseudocode only. Python uses = for assignment, so the line should be Total = Count * 2.
Q3
D — Name is text and Score is a number, so + cannot join them and gives a TypeError. Separate the values with commas: print(Name, Score + Bonus).
Q4
B — input() returns text, so multiplying Length by Width causes an error. A number must be read with float(input()).
Q5
A — A double == compares values, it does not assign. Use a single = to store the input in Age: Age = int(input()).
