Using loops in Python automates and repeats tasks efficiently. But sometimes a condition may arise where you want to exit the loop completely, skip the iteration, or ignore this condition. This can be done with loop control statements . Loop control statements change execution from its normal sequence. When execution leaves a scope, all automatic objects created in that scope are destroyed. Python supports the following control statements.

• Break statement
• Continue statement
• Pass Application

Break Statement

The break statement is used to end a loop or statement in which it is present. The control will then jump to the statements after the break statement, if available. If a break statement is present in a nested loop, it terminates only those loops that contain a break statement.

Syntax :

 break 

Example:
Consider the situation when you want to iterate over a string and print all characters until you meet the letter “e” or “s”. It is stated that you must do this with a loop, and only one loop is allowed. 
This is where the break statement is used. What we can do is iterate over the lines, using either a while loop or a for loop and every time we have to compare the iterator value with “e” or “s”. If it`s & # 39; e & # 39; or & # 39; s & # 39;, we will use a break statement to break out of the loop.

Below is the implementation.

Exit:

 ge Out of for loop ge Out of while loop  
 Continue Statement 
 
  Continue  is also a loop control statement, just like a break statement. The  continue  statement is the opposite of the break statement, instead of terminating the loop, it forces the next iteration of the loop to run. 
 As the name suggests, the continue statement causes the loop to continue or to perform the next iteration. When the continue statement is executed in a loop, the code within the loop following the continue statement will be skipped and the next iteration of the loop will begin. 
 
  Syntax :
 
 continue  
  
 
  Example:  
 Consider the situation, when you need to write a program that prints a number between 1 and 10, not 6. It is specified that you should do this with a loop, and only one loop is allowed. 
 This is where the  continue  statement is used. Here we can start a loop from 1 to 10, and every time we need to compare the value of the iterator with 6. If it is 6, we will use the continue statement to go to the next iteration, without printing anything else, we will print the value.  
 Below is the implementation of the above idea: 
 
 
 
  
 
 
 
 
  # Python program for  
  # demonstrate continued  
  # statement  
 
  
  # loop from 1 to 10  
 
  for   i   in   range   (  1  ,   11  ): 
 
   
 
   # If I am 6  
 
   # go to next iteration  
 
   # no printing  
 
   if   i   =   =   6  : 
 
   continue  
 
   else  : 
 
   # otherwise output the value  
 
   # I  
 
   print   (i, end   =  " " )  
 
 
 
 
 
  
 
  Exit: 
 
 
 
 1 2 3 4 5 7 8 9 10 
 Complete application 
 As the name suggests, the pass statement simply does nothing. The pass statement in Python is used when a statement is required syntactically, but you don`t want any command or code to run. It is like a  null  operation, since nothing happens if it is done. The  Pass  operator can also be used to write empty loops. Pass is also used for empty control statement, function and classes. 
  Syntax :
 pass 
  Example:  






  # Python program for demonstration  
  # pass the statement   
  
  
  s   =  " geeks " 
   
  # Empty loop  
  for   i   in   s: 
    # No errors will occur  
   pass  < / p> 
  
  # Empty function  
  def   fun (): 
    pass  
   
  # No errors will occur  
  fun () 
  
  # Skip Statement  
  for   i   in   s: 
   if   i   =   =   `k`  : 
   print   (  ` Pass executed`  ) 
   pass  
   print   (i)  





  
  Exit: 
 gee Pass executed ks 
 In the above example, when the value of i becomes "k", the pass statement did nothing and hence the letter "k" is also printed.
