Really simple (but flexible) python progress bar

progress.py

import sys

def progress(current, total=1., text='', width=80, fillchar='#', padchar=' ', startchar='[', endchar=']', done='\n'):
    
    if current > total:
        raise ValueError('current is greater than total')
    
    if text is not '':
        text = text + ': '
    
    bar = width-len(startchar)-len(endchar)-len(text)
    fill = int(float(bar)*current/total)
    pad = bar - fill

    reset = '' if current == 0 else '\r'

    if done is not '\n':
        done = '\r'+done+' '*(width-len(done))+'\n'

    if current < total:
        done = ''
    
    sys.stdout.write(reset+text+startchar+fillchar*fill+padchar*pad+endchar+done)
    sys.stdout.flush()



import time

print("This text is before the progress bar and will not be cleared.")

n=17
progress(0,n,'Completed',fillchar='=',padchar='-')
for i in range(n):
    time.sleep(1)
    progress(i+1,n,'Completed',fillchar='=',padchar='-',done='The thing has completed.')

print("This text is after the progress bar and will be on a new line.")
