python end loop code example

Example 1: python get out of loop

while True:
  print('I run!')
  break
print('Not in loop!')

Example 2: python exit for loop

# python 3

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

Example 3: python while continue

## When the program execution reaches a continue statement, 
## the program execution immediately jumps back to the start 
## of the loop.
while True:
    print('Who are you?')
    name = input()
    if name != 'Joe':
        continue
    print('Hello, Joe. What is the password? (It is a fish.)')
    password = input()
    if password == 'swordfish':
        break
print('Access granted.')

Example 4: 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 5: 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 )

Example 6: how to exit a loop in python

print("enter a number")
num=int(input())
for i in range(2,num+1):
    if(num%i==0):
        print("smallest divisor is",i)
        break
