Print over last line in terminal

Question

When using wget in a Linux terminal, the last line printed in the terminal is being overwritten as the download progresses, to reflect the progress.

Can I overwrite the last line of the terminal in Python? (targeting Linux only)

You can use escape sequences.

You might be familiar with "\n" for new line. There's also "\b" for backspace and "\r" for carriage return.

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

this doesn't overwrite the *last* line in the terminal. It can overwrite the current line. – jfs Oct 16 '14 at 01:10
You're right. I assumed that the current line is the last line. – Fedalto Oct 16 '14 at 01:25

You could use blessings module to write on the last line in a terminal on Linux:

from blessings import Terminal # $ pip install blessings

t = Terminal()
with t.location(0, t.height - 1):
    print('This is at the bottom.')
