how to end a for loop in python code example
Example 1: python for loop start, end
my_list = [1, 2, 3]
my_list.reverse() # my_list is modified
print(my_list) # '[3, 2, 1]'
my_revert = my_list[::-1] # my_list stays [3, 2, 1]
print(my_revert) # '[1, 2, 3]'
# Item by item reverse with range(<start>, <end>, <step>)
for i in range(len(my_list), 0, -1): # my_list is [3, 2, 1]
print(my_list[i-1]) # '1' '2' '3'
for i in reversed(range(len(my_list))):
print(my_list[i]) # '1' '2' '3'
Example 2: python get out of loop
while True:
print('I run!')
break
print('Not in loop!')
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 break for
number = 0
for number in range(10):
if number == 5:
break # break here
print('Number is ' + str(number))
print('Out of loop')
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
print("smallest divisor is",i)
break
