Python break statement

The Python break statement, like in C or the C++ programming language, breaks or closes a for loop or a while loop.

The break statement can be used to terminate a loop statement, i.e., False condition or loop condition has not yet been completed, will stop the execution loop.

The break statement can be used in a while and for loop.

If you are using nested loops, break statement to stop the execution of code gets very confusion, it stops the innermost loop.

Python language break statement syntax:
The syntax for the break statement is: (drum rolls)

Example:

The example below creates two loops, both which are stopped using the break statement. In the first example we use strings, in the second example a plain variable counter var.

#!/usr/bin/python

for letter in 'Python': # first instance
   if letter == 'h':
      break
   print('current letter:', letter)

var = 10 # second instance
while var> 0:
   print('current variable values:', var)
   var = var -1
   if var == 5: # var is equal to 5 when the variable loop exits
      break

print("Good bye!")

The results of the above examples:

current letter: P
current letter: y
current letter: t
current variable values: 10
current variable values: 9
current variable values: 8
current variable values: 7
current variable values: 6
Good bye!
