how to break out of a while loop python code example

Example 1: python exit for loop

# python 3

for x in range(1, 10):
    print(x)
    if x == 4:
        break
# prints 1 to 4

Example 2: python how to skip iteration

nums = [7,3,-1,8,-9]
positive_nums = []

for num in nums:
    if num < 0: #skips to the next iteration
        continue
    positive_nums.append(num)
        
print(positive_nums) # 7,3,8

Example 3: python exit loop iteration

alphabet = ['a' , 'b' , 'c' , 'd' ]
for letter in alphabet:
  if letter == 'b' :
    continue
    #continues to next iteration
  print( letter )
for letter in alphabet:
  if letter == 'b' :
    break
    #terminates current loop
  print( letter )
for letter in alphabet:
  if letter == 'b' :
    pass
    #does nothing
  print( letter )
