Want to avoid the blank new line in the last of the output

Question

I don't want the empty line to be printed in the output

I have tried end="" but since print is in loop, it is not working

def main():
    a=int(input())
    b=int(input())
    for i in range(a,b+1):
        prime=0
        for x in range(2,i):
            if(i%x==0):
                prime=prime+1
            else:
                prime=prime+0
        if(prime==0):
            print(i, end="") 
main()

Actual result:

Expected:

It is hard to distinguish your expected result from your actual result. Also, your code prints no newlines at all, so neither your expected nor your actual output match the code. — John Coleman, Jul 03 '19 at 16:19
With that code, all the numbers should be written on one line without any spaces. Are you adding newlines somehow? If the numbers are all on their own line then naturally the last one will end with one as well — Kelo, Jul 03 '19 at 16:24

You might want to look at this: how can I remove a trailing newline. It states to use .rstrip() but you should read the docs to make sure.

One possibility is to assemble the results into a list and print that list (joined by '\n') at the end:

def main():
    a=int(input())
    b=int(input())
    results = []
    for i in range(a,b+1):
        prime=0
        for x in range(2,i):
            if(i%x==0):
                prime=prime+1
            else:
                prime=prime+0
        if(prime==0):
            results.append(i)
    print('\n'.join(str(i) for i in results))
main()

I am not completely sure what you are trying to do, you could also experiment with replacing the print statement in the above code by

print('\n'.join(str(i) for i in results), end = '')

You can dynamically print things out like this

for i in range(10):
    print(i, sep=' ', end='', flush=True)

This will output:

123456789

see Print in one line dynamically for more algorithms that might fit what you need!
