Given this Python code snippet running in a Google Cloud Function:

import os
api_key = os.getenv('API_KEY')
print(f"Key: {api_key}")

If the environment variable API_KEY is not set, what will be printed?

Step-by-Step Solution

Solution:

Step 1: Understand os.getenv behavior
When the environment variable is missing, os.getenv returns None by default.
Step 2: Analyze the print output
The f-string converts None to the string 'None', so the output is 'Key: None'.
Final Answer:
Key: None -> Option C
Quick Check:
Missing env var returns None [OK]

Quick Trick: os.getenv returns None if variable missing [OK]
