Answer: Python Puzzler #1193

The answer is A. The program prints:

[1, 3, 5, 7, 9]

Checked by running the program for real.

range(1, 10, 2) counts from 1 in steps of 2 and stops before 10.

print(list(range(1, 10, 2)))

Try it: change one number in the program and predict the new output before you run it.
