?What is the difference between a for loop and a while loop in Python

A for loop and a while loop in Python serve different purposes and are used in different scenarios: for loop: A for loop is used to iterate over a sequence (such as a list, tuple, dictionary, set, or string). It is typically used when you know beforehand how many times you want to execute a statement or a block of statements. The syntax is concise and allows easy iteration through each element in the sequence. Example: python Copy code for i in range(5): print(i) This loop will print numbers from 0 to 4. while loop: A while loop continues to execute as long as a specified condition is true. It is more flexible and can be used when the number of iterations is not known beforehand. The loop will keep running until the condition becomes false. Example: python Copy code i = 0 while i < 5: print(i) i += 1 This loop will also print numbers from 0 to 4, but the condition is checked before each iteration.

?How do the break and continue statements affect the flow of a loop in Python

The break and continue statements are used to alter the normal flow of loops in Python: break statement: The break statement is used to exit a loop prematurely. When break is encountered inside a loop, the loop terminates immediately, and the control flow jumps to the statement following the loop. This is useful for stopping the loop based on a condition other than the loop's main condition. Example: python Copy code for i in range(10): if i == 5: break print(i) This loop will print numbers from 0 to 4 and then terminate when i equals 5. continue statement: The continue statement is used to skip the rest of the code inside the loop for the current iteration and proceed to the next iteration. It effectively ends the current iteration and jumps back to the beginning of the loop for the next iteration. Example: python Copy code for i in range(5): if i == 3: continue print(i) This loop will print numbers 0, 1, 2, 4, skipping the number 3. Both statements provide control over the loop's execution, allowing for more sophisticated and flexible loop behavior.
