Could anyone explain me the output?

Question

i = 0
while 1==1:
print(i)
i = i +1
print("Finished")

Output:
0
Finished
1
Finshed
2
Finished
3
Finished
.
.
.

So on.

Answer 1

i is a variable with the value 0.

while 1 == 1: is the same as while True:
wich is an infinite loop (nothing tells it to stop)

each time it loops it first prints the value of i, then adds 1 to the value of i, then prints finished.

it will do this forever.

Answer 2

Do you think in both cases statement is always true?

Answer 3

Actually I was confused that why the Finished message also printing alternatively along with infinite loop.

Answer 4

1 == 1 will always be True, infinite loop.
i = 0;
Everytime it loops add 1 to i, means increment i by 1.

Answer 5

i assume you want it to print "finished" at the end but it will never do that since its an infinite loop.
It's all about indentation in the loops
try this:

i = 0
while i < 6:
print(i)
i += 1
print('Finished')

Answer 6

Try to write break after print ("finish ")
This will keep on counting till infinity but finish will print only once

Answer 7

"==" sign is a Boolean function to represent if a vale is true or false
So you took i=0
In the loop you used 1 is true so it prints all the values and becomes an infinite loop

Answer 8

Like shift the print("finished ")
Just below the inundation of while

Answer 9

He literally just said to do what that code i showed above does.

Answer 10

It ran exactly the way you programmed it. Look at the subtle differences between the code you posted and the code i posted. Copy and paste mine if it helps, you got it man. **Indentation**

Answer 11

So you set the variable i = 0 (I assume a counter)
You then declared a while loop with the condition that it will run while 1 == 1 which is the same as saying while True

As 1 is always going to be equal to 1 the loop will become an infinite loop (AKA never ending)
There is only 1 way to exit this current loop, that would be with the break keyword which breaks out of the loop.

Every iteration of this loop you are iterating your i variable and adding 1 to it. The best way to avoid an infinite loop is to set a boolean outside that will become true/ false at some point that will subsiquently exit the loop. Having either while 1==1 or while True is considered bad practice among a lot of python programmers.

Heres an example.

Answer 12

i agree Vivek Vadi

Answer 13

I was confused that why "Finished" also printing alternatively along with the loop

Answer 14

Why do you disliking it?
i am just clearing my doubt.
There is nothing useless here.
It's quite weird.

Answer 15

Finished is also placed in side the loop
If you backspace the print command of finished then it won't print repeatedly

Bhavya gupta sorry i didn't get you. Tum hindi mein bhi samjha sakti ho

Answer 17

Slick let me try

Answer 18

What if we use 'break' statement before print("Finished")?

Answer 19

Give it a shot and see. Thats what the playground is for

Answer 20

Case 1: i = 0
while 1==1:
print(i)
i = i +1
break
print("Finished")

Output:
0
Finished

Case2:
i = 0
while i<6:
print(i)
i = i +1
print("Finished")

Output:
0
Finished

Both cases same output.
