When writing carriage return to a pycharm console the whole line is deleted?

Question

I have a program in Python that makes extensive use of the line feed character to produce the effect of an updating console line (specifically a progress bar).

When

Answer 1

Be careful with short time between prints and short length of printed strings, printing can be tricky and print few values in one row.

To workaround that you can add second \r after white character:

for i in range(10):
    print("\r \r{0}".format(str(i)), end='')
    time.sleep(0.1)

Answer 2

The bug is still active and it was reported here. For now if you Use the Run > Configuration > "Emulate Terminal in Output Console" the carriage return will function as intended.

Answer 3

I recently ran into the same problem, and found a solution. The answer is actually in your post. As you said, the carriage return deletes the whole line. To avoid the issue, print the carriage return only when you print the new line, like so:

Print each line with the carriage return at the start, and without the default end='\n'. Didn't need the flush, though I didn't do much testing.

print('\rxxx', end='')
# sys.stdout.flush()
time.sleep(1)

Continue like this...

print('\rZZ', end='')
time.sleep(1)

print('\ryyy', end='')
time.sleep(1)

To keep the last printout, keep the default end.

print('\r===')

Hope this works for you.
