Python - Advanced Exception Handling

nums = [3, 5, -1, 7]
for n in nums:
    ?

Aassert n > 0; f"Number {n} is not positive"

Bassert n > 0: f"Number {n} is not positive"

Cassert n > 0, f"Number {n} is not positive"

Dassert (n > 0), "Number n is not positive"

Step-by-Step Solution

Solution:

Step 1: Understand assert in loop context
We want to check each number and stop if any is not positive, showing which one failed.
Step 2: Check syntax correctness
assert n > 0, f"Number {n} is not positive" uses correct assert syntax with a comma and f-string for message. Others use invalid punctuation.
Final Answer:
assert n > 0, f"Number {n} is not positive" -> Option C
Quick Check:
Assert syntax: condition, message with comma [OK]

Quick Trick: Use comma and f-string for assert message in loops [OK]
