WHILE LOOPS

Python - While Loops

Python Loops :

Python has two primitive loop commands:

• while loops


• for loops

The while Loop :

A while loop statement in Python programming language repeatedly executes a target statement as long as a given condition is true.

Print i,as long as i<8

i=1
while i<8:
 print(i)
i+=1

====o/p====
2
3
4
5
6
7

Note: remember to increment i, or else the loop will continue forever.

The while loop requires relevant variables to be ready, in this example we need to define an indexing variable, i, which we set to 1.

The break Statement :

With the break statement we can stop the loop even if the while condition is true.

i = 1
while i < 6:
  print(i)
  if i == 3:
    break
  i += 1

====o/p====
1
2
3

The continue Statement :

With the continue statement we can stop the current iteration, and continue with the next.

Continue to the next iteration if i is 3:

i=0
while i<6:
 i+=1
 if i == 3:
 continue
   print(i)

====o/p====
1
2
4
5
6
# Note that number 3 is missing in the result

The else Statement :

With the else statement we can run a block of code once when the condition no longer is true.

Print a message once the condition is false:

i=1
while i<6:
   print(i)
 i+=1
else:
   print("1 is no longer less than 6")

====o/p====
1
2
3
4
5
1 is no longer less than 6

True statement :
i = 1
while i<6:
    print(i)
    i += 1
else:
        print("1 is less than 6")
    
=====o/p====
1
2
3
4
5
1 is less than 6
