In general, for loops are used when you know exactly how many times you plan to run a loop; a while loop is used when the number of iterations is uncertain. Conditional Statement Basic Structure: if ...

With each loop, the iter_var iteration variable is set to the current elementof the iterable (sequence, iterator, or object that supports iteration), presumably for use in suite_to_repeat. F) break ...

This post explains how to use loops in Python. You'll learn FOR loops, WHILE loops, BREAK, CONTINUE and more. A crucial skill for coding!

The use of if elif else conditional statements in Python. Using Python for loop for repetitive tasks. Using Python for loop to print numbers. Using Python while loop for repetitive tasks.

We can also perform conditional reductions, using a where argument: x2 = np.add.reduce(x1, where=np.greater(x1, 1)) ... Loops in Python over NumPy arrays can be optimized automatically this way.

With each loop, the iter_var iteration variable is set to the current elementof the iterable (sequence, iterator, or object that supports iteration), presumably for use in suite_to_repeat. F) break ...
