python loop 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

# 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 3: how to write a while statement in python

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

Example 4: while loop python

while (condition):
  doThis();

Example 5: 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!")

Example 6: how to use a while loop in python

x = True

#While the condition is true the code inside the while loop will execute
#Once to condition is false the loop will break and the code past the while loop
#will execute
while x == True:
	print("x is true")
print("If this prints then x is not true")
