Question

The slicing operations in the given code work as follows:

• myStr[:4] extracts the first 4 characters, which are "MISS".
• myStr[-5:] extracts the last 5 characters, which are "SIPPI".
• These two substrings are concatenated with a "#" in between, resulting in "MISS#SIPPI".

• A. YELLOW # RED #
• B. RED # GREEN #
• C. GREEN # RED #
• D. YELLOW # GREEN #

Hint:

The random.randrange(K)} function generates a random integer between \( 0 \) and \( K-1 \). Use loops carefully to trace all potential outputs.

Answer 1

The Correct Option is A

The code iterates over the range \( (2, 0, -1) \), which means \( K = 2 \) and \( K = 1 \). For each iteration:

• When \( K = 2 \): random.randrange(2) generates either \( 0 \) or \( 1 \). The output could be \( \text{Signal}[0] \) ('RED') or \( \text{Signal}[1] \) ('YELLOW').
• When \( K = 1 \): random.randrange(1) always generates \( 0 \). The output is \( \text{Signal}[0] \) ('RED').

One possible output is YELLOW \# RED \#, which matches option (a).
