Python: How to print percentage

Question

I have a question about printing.

When I am printing:

"Work in progress(0%)"

How do I only edit the bold part?

If printing on the command line you can use:

import time
print "Work in progress( 0%%)", # Python 2 print without newline
for work_done in range(10):
    print "\b\b\b\b\b%2d%%)" % work_done, # Backspace then overwrite
    time.sleep(1)

This will print your base line and then backspace each time that it is rewritten. N.B. for python 3 you would need print(whatever, end=None)

doesn't work for me on python 2.7 – Hassan Mehmood May 08 '16 at 06:33
@HassanMehmood What do you get? – Steve Barnes May 08 '16 at 07:03
I get bunch of numbers in a row. But when I added a time.sleep, it works completely fine. – Hassan Mehmood May 08 '16 at 07:17
I would expect there to be some work going on in the `work_done` loop which will give the terminal time to catch up so you probably will not need a `time.sleep` – Steve Barnes May 08 '16 at 07:19
Yeah right, but for debugging purposes I added to visually observe the change. – Hassan Mehmood May 08 '16 at 07:21

Use the .format:

 print "Work in progress({0}%)".format(some_variable_holding_percentage)

percentage = 15
print "Work in progress({:d}%)".format(percentage)

output:

Work in progress(15%)

Thanks much, but I think this will print "Work in progress" several times. How do I only change the percentage? – JKC May 08 '16 at 07:05
This will print "Work in progress(15%)" only once. – Yaron May 08 '16 at 07:09
JKC - Did you try to execute it? – Yaron May 08 '16 at 07:09
