This is shown below. – Julien Sep 8 '17 at 5:13. Lastly, we learnt about break, continue, and pass statements to control loops. It may be tempting to choose the closest analogy to the C code possible in Python: But beware, modifying i will not effect the flow of the loop as it would in C. Therefore, using a while loop is actually a more appropriate choice for porting that C code to Python. Note that the range function is zero based. Programming is like a circus: you gotta keep the lions in the ring. Now, the looping part comes here we are using the for loop in combination with the range function. As you can see, these loop constructs serve different purposes. @user2357112 While loop can be twice as slow compared to a for-loop. With range, you can print list elements between the given range.
