Break statement in Python

Guide Kit

In Python, the break statement is a control statement used to terminate a loop when a certain condition is met immediately. It is commonly used for & while loops.

When a break statement is encountered inside a loop, the loop is immediately terminated, and program control is transferred to the next statement after the loop. This means that any remaining iterations of the loop are skipped. The break statement is often combined with conditional statements, such as if, to test for a specific condition and exit the loop when that condition is met.

A break statement is a useful tool in programming as it allows you to exit a loop prematurely when a certain condition is met.

Terminating infinite loops: If you accidentally create an infinite loop in your code, it can cause your program to hang or crash. Using the break statement, you can terminate the loop when a specific condition is met, preventing an infinite loop.
Improving program efficiency: Sometimes, you may have a loop that performs many iterations. Using the break statement, you can terminate the loop early if you determine that no further iterations are necessary. This can save processing time and improve the efficiency of your program.
Simplifying code: When working with nested loops, it can be difficult to determine when to terminate the outer loop. Using the break statement in the inner loop, you can exit the inner loop when a condition is met and then continue executing the outer loop.
Creating flexible code: Sometimes, you may want to exit a loop based on a user's input or other external factors. Using the break statement, you can create more flexible code that can be terminated based on specific conditions, allowing you to tailor your program to different use cases.

The break statement provides a simple way to control the flow of a loop, allowing you to exit the loop when needed and continue with the rest of your program.

Dependent Libraries :

for i in range(1,10):
      if i == 5: #when i is 5 this will be true
           break #break the loop exits the loop
      #----------------------This is not run when i==5 because the loop already ended
      print("number is ", i)

for i in range(1,10):

     print("number is ", i) #put this in front
     if i == 5: #when i is 5 this will be true
           break #break the loop exits the loop

for i in range(1,10):

     if i > 5: #when i is 5 this will be false, so the loop doesn't break
           break #break the loop when i > 5 (ie. 6) so now the print() isn't reached and will not print 6

     print("number is ", i) #since the loop didn't break when i is 5, it printed i

for i in range(1,10):
    if i > 5:
         break #exits here skips the print since it's after this
    print(i) #the print statement is here so when i > 5 this is not reached
#on the other hand:
for i in range(1,10):
    print(i) #the print statement is in front of the break statement so now it will print 6 too since the loop hasn't break yet
    if i > 5:
         break #exits here after the print()
#output also includes 6

for i in range(1,10):
    print(i) #only 1 got printed since the loop break before it get to 2
    if i < 5: #when i < 5 so it breaks in the first loop when i is 1
        break #exits the loop
