4 cze 2021 · While Loop Example. Exercise: Find and print all of the positive integers less than or equal to 100 that are divisible by both 2 and 3. In file DivisibleBy2and3.py: def main(): num = 1 while (num <= 100): if (num % 2 == 0 and num % 3 == 0): print( num, end=" " ) num += 1. print() main() Running the program:
The while loop is the most simple of the loops in Python. The syntax for the loop is as follows: while <Boolean expression>: stmt1 stmt2 ... stmtn stmtA The manner in which this gets executed is as follows: 1) Evaluate the Boolean expression. 2) If it’s true a) Go ahead and execute stmt1 through stmtn, in order. b) Go back to step 1.
Python while Loop. In Python, we use a while loop to repeat a block of code until a certain condition is met. For example, number = 1 while number <= 3: print (number) number = number + 1. Output. 1 2 3. In the above example, we have used a while loop to print the numbers from 1 to 3.
•One loop executes inside of another loop(s). •Example structure: Outer loop (runs n times) Inner loop (runs m times) Body of inner loop (runs n x m times) • Program name: nested.py i = 1 while (i <= 2): j = 1 while (j <= 3): print("i = ", i, " j = ", j) j = j + 1 i = i + 1 print("Done!")
