How is randomness introduced into a Karel program?

Randomness in a Karel program is effectively introduced through the use of random number generators, provided that the programming environment supports them. When a random number generator is integrated into a program, it allows Karel to make decisions based on chance, leading to unpredictable outcomes in its actions. For example, if Karel is programmed to choose a direction randomly, it could lead to different paths being taken on each execution of the program, creating diverse scenarios and behaviors each time it runs.

Repetitive commands or timers can create patterns or delays but do not introduce true randomness. Randomizing color changes can add visual variety to the program but does not affect the fundamental logic or behavior of Karel in a way that introduces randomness into its decision-making processes. Therefore, utilizing a random number generator is the most effective and accurate method to incorporate randomness into Karel’s actions.
