python for i while code example

Example 1: python do while

# Python does not have a do-while loop. You can however simulate
# it by using a while loop over True and breaking when a certain
# condition is met.
# Example:
i = 1
while True:
    print(i)
    i = i + 1
    if(i > 3):
        break

Example 2: python while loop

while <condition>:
  <run code here>
  
# for example,
i = 0
while True:
  i += 1
  # i will begin to count up to infinity
while i == -1:
  print("impossible!")
