What type of loop is guaranteed to run at least once in Python?

In Python, the loop that is guaranteed to run at least once is the do-while loop. Although Python does not have a built-in do-while loop, the concept is that the body of the loop is executed first before checking the condition. This ensures that even if the condition evaluates to false on the first evaluation, the code inside the loop will still execute at least once.

While Python offers other types of loops, such as for loops and while loops, these do not have that guarantee. A for loop iterates over a sequence (like a list or a range), and its execution depends on the presence of items in that sequence. A while loop evaluates its condition before executing its body, meaning if the condition is false at the onset, the body of the loop may not be executed at all.

Nested loops refer to loops contained within other loops, and while they can be used in various programming structures, they do not inherently guarantee that their inner loop will run at least once since this depends on the outer loop's conditions.

Hence, although there isn't a direct equivalent of a do-while loop in Python, the concept embodies the catch that certain structures are guaranteed to execute their body at least once, which is why it is considered the
