# Example 1: Simple while loop
count = 0
if count < 5:
  print "Hello, I am an if statement and count is", count

while count <= 9:
  print "Hello, I am a while and count is", count
  count += 1

# Example 2: Another simple while loop
loop_condition = True

while loop_condition:
  print "I am a loop"
  loop_condition = False

# Example 3: Just another example
num = 1

while num <= 10:  # Fill in the condition
  # Print num squared
  print num ** 2
  # Increment num (make sure to do this!)
  num += 1

# Example 4: Using while loop to prevent unexpected input
choice = raw_input('Enjoying the curse? (y/n): ').lower()

while not ((choice == 'y') or (choice == 'n')):  # Fill in the condition (before the colon)
  choice = raw_input("Sorry, I didn't catch that. Enter again: ").lower()

# Example 5: Infinite loop and exiting it with a break
# The difference here is that this loop is guaranteed to run at least once
# Do While alternative
count = 0

while True:
  print count
  count += 1
