python while and code example

Example 1: python while

# a while loop repeats its instructions as long as the condition is met
# this one will loop indefinitely
python_is_cool = True

while python_is_cool:
  print("I love python!")
  
# while loops are useful when you don't know the number 
# of times you want to iterate in advance

Example 2: how to write a while statement in python

myvariable = 10
while myvariable > 0:
  print(myvariable)
  myvariable -= 1

Example 3: while loop python

while (condition):
  doThis();

Example 4: 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!")
