Also, share what version of Python, OS and editor you are using.

Have you tried swapping the print and return statement in the
if-elif-elif-else loop ?

Hi Dilip,

This error has nothing to do with Python or it's versions.
OS does not have the support for these unicode characters. You need to fix
that.

[Tutor] Howto display progress as cmd is being executed via subprocess ?

[Ramanathan Muthaiah]

Hello All,

Am aware of the module called 'progressbar' that can do this magic of
displaying progress as the cmd is executed.
In fact, I have a test code to show progress and tried, it works.



from progressbar import *
import time

def main():
progress = ProgressBar()
for num in progress(range(80)):
time.sleep(0.15)

if __name__ == '__main__':
main()

And, I have this piece of code that executes set of cmds stored in 'cmd'
variable.
This too works without any issues until now.

try:
 dlog = subprocess.check_output([cmd],
stderr=subprocess.STDOUT, shell=True)
except subprocess.CalledProcessError, e:
dlog = e.output

Question:

Am lost as to how to combine the progressbar and subprocess code snippets
to show the progress as the cmd is being executed.

Any ideas on how this can be done ?
