Quick Questions
Shade in the A or B circle for each question.
1. What does 'Python'[0:3] return?
2. What does 'hello'[:2] return?
3. What does 'hello'[3:] return?
4. Is the stop index included in a slice?
5. What does 'abcdef'[::2] return?
B
Match the Pairs
Draw a line connecting each item on the left to its match on the right.
| Left column | Right column | |
|---|---|---|
| 1'hello'[1,4] | AOk: Reverses the string | |
| 2'hello'[10:20] | BValid: Returns 'hel' | |
| 3'hello'[:3] | CError: Use colon not comma | |
| 4'hello'[::-1] | DInvalid: But returns '' not error | |
| 5print('hello'[1:4]) | EOutput: ell | |
| 6print('python'[2:]) | FOutput: thon |

D
Fill in the Blanks
Complete each line of code by filling in the missing parts.
1.
word = 'Python'
print(word[_:3])
2.
word = 'hello'
print(word[:_])
3.
word = 'hello'
print(word[_:])
4.
word = 'hello'
print(word[::__])
5.
text = 'abcdef'
print(text[1:_])
E
Spot the Error
Shade in the letter of the line that contains an error.

Answer Key
Strings – Slicing
Section A: Quick Questions
Q1
B — 'Pyt'
Q2
A — 'he'
Q3
B — 'lo'
Q4
A — No it stops before it
Q5
A — 'ace'
Section B: Match the Pairs
Q1
'hello'[1,4] → Error: Use colon not comma
Q2
'hello'[10:20] → Invalid: But returns '' not error
Q3
'hello'[:3] → Valid: Returns 'hel'
Q4
'hello'[::-1] → Ok: Reverses the string
Q5
print('hello'[1:4]) → Output: ell
Q6
print('python'[2:]) → Output: thon
Section C: Definitions
Q1
Slice — Extract a portion of a string using [start:stop].~~[start:stop]Section D: Fill in the Blanks
Q1
word = 'Python'
print(word[0:3])Q2
word = 'hello'
print(word[:3])Q3
word = 'hello'
print(word[2:])Q4
word = 'hello'
print(word[::-1])Q5
text = 'abcdef'
print(text[1:5])Section E: Spot the Error
Q1
B — Use colon : for slicing, not comma
Q2
B — Step cannot be 0: causes ValueError
Q3
B — Use square brackets [] for slicing, not parentheses ()
Q4
B — Trailing colon without step is fine but unnecessary: remove it for clarity
Q5
A — Start must be before stop: -4 comes before -1 in the string
