for and while loop in python 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: python while loop

# A while loop is basically a "if" statement that will repeat itself
# It will continue iterating over itself untill the condition is False

python_is_cool = True
first_time = True

while python_is_cool:
	if first_time:
		print("python is cool!")
    else:
      first_time = False
      
print("Done")

# The while loop can be terminated with a "break" statement.
# In such cases, the "else" part is ignored. 
# Hence, a while loop's "else" part runs if no break occurs and the condition is False.
# Example to illustrate the use of else statement with the while loop:
  
counter = 0

while counter < 3:
    print("Inside loop")
    counter = counter + 1
else:
    print("Inside else")

Example 3: how to write a while statement in python

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

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!")

Example 5: how to do a while loop python

while True: #True can be replaced with a different condition
  #result
