What are the two main types of loops in Python?

• A. do-while and for loop
• B. for loop and while loop
• C. foreach and while loop
• D. if loop and while loop

Answer: (B)

The two main types of loops in Python are the for loop and the while loop. The for loop is used to iterate over a sequence (like a list, tuple, or string) or other iterable objects, allowing you to execute a block of code for each element in that sequence. It is particularly useful for tasks that require straightforward iteration. On the other hand, the while loop runs as long as a specified condition is true. It’s commonly used in scenarios where the number of iterations is not known beforehand and is determined by the condition specified within the loop. Together, these loops provide Python developers with powerful tools for controlling the flow of execution based on sequences and conditions. Other options mentioned do not accurately represent common loop types in Python. For example, a do-while loop is not available in Python, and the if statement is a conditional construct rather than a loop.
