PyCharm console not printing in the same line, but does in debug console

Question

I want to show a progress bar in PyCharm, but the console doesn't seem to be printing on the same line. Weird thing is that if I run the code in debug mode, the debug console works properly, printing the progress bar in the same line). Here's the code snippet for the progress bar (source):

import sys
import time

for i in range(10):
    sys.stdout.write("\r{0}".format(str(i)))
    sys.stdout.flush()
    time.sleep(1)

I'd appreciate if you could help me identify what's wrong with the console.
