how to stop for loop python code example

Example 1: how to exit a double loop in python

for word1 in buf1: 
    find = False 
    for word2 in buf2: 
        ... 
        if res == res1: 
            print "BINGO " + word1 + ":" + word2 
            find = True 
            break             # <-- break here too
    if find: 
        break

Example 2: python break for loop

#in Python, break statements can be used to break out of a loop
for x in range(5):
    print(x * 2)
    if x > 3:
        break

Example 3: python exit for loop

# python 3

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

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 break a loop in python

x = 0
while True:
    x += 1
    if x == 10:
        break
