Raspberry Pi - Data Logging and Databases

What will this Python code print when run on Raspberry Pi?

data = []
for i in range(3):
    data.append(f"Reading {i}: {i*10}C")
print(data)

A['Reading 1: 10C', 'Reading 2: 20C', 'Reading 3: 30C']

B['Reading 0: 0C', 'Reading 1: 10C', 'Reading 2: 20C']

C['Reading 0: 10C', 'Reading 1: 20C', 'Reading 2: 30C']

D['Reading 0: 0C', 'Reading 1: 1C', 'Reading 2: 2C']

Step-by-Step Solution

Solution:

Step 1: Understand the loop and string formatting
Loop runs i=0,1,2; each appends 'Reading i: i*10C' to list.
Step 2: Calculate each appended string
For i=0: 'Reading 0: 0C', i=1: 'Reading 1: 10C', i=2: 'Reading 2: 20C'.
Final Answer:
['Reading 0: 0C', 'Reading 1: 10C', 'Reading 2: 20C'] -> Option B
Quick Check:
Loop i*10 matches output [OK]

Quick Trick: Range(3) loops 0,1,2; multiply i by 10 [OK]
