Not able to break out of while loop

Question

I have the following code:

with open('data.csv') as csvfile:
    data = csv.reader(csvfile, delimiter=' ')
    row_count = sum(1 for row in data)
    counter = 0
    while counter < row_count:
        for i in range(20):
            print('hello')
        counter = counter +1
        print('sleeping')
        time.sleep(10)

The data.csv file have over 100 lines. But I want my counter to print only 20 lines of hello and then sleep for 10 seconds and restart the operation again until it matches the number in row_count .

The output is fine in that it prints hello 20 times and prints sleep with a delay but this loop does not end when it reaches row_count which is 100. This keeps on running. What can I do for this loop to end after it reaches 100?

Answer 1

Your identation is incorrect. If you ident the line where you increment the counter it will do what you want. Currently you are doing 100 (or whatever row_number equals) lots of 20.

EDIT: I wrote this thinking that you wanted to print "Hello" row_number times, but reading your post back it seems that you actually want to print "Hello" row_number * 20 times, in which case surely 2000 is the correct answer?
