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 executes a loop where the loop variable \( K \) takes values \( 2 \) and then \( 1 \). In each step of the loop:

• For \( K = 2 \): The function call random.randrange(2) produces either \( 0 \) or \( 1 \). Consequently, the result can be either \( \text{Signal}[0] \) (which corresponds to 'RED') or \( \text{Signal}[1] \) (which corresponds to 'YELLOW').
• For \( K = 1 \): The function call random.randrange(1) will always return \( 0 \). The output in this case is \( \text{Signal}[0] \) ('RED').

An example of a potential output sequence is YELLOW \# RED \#, aligning with option (a).
