Python: printProgressBar function with autoresize option

print-progress-auto.py

# This version of the printProgressBar function implements an optional autoresize argument.
# It has been updated from a previous version to use the shutil Python module to determine
# the terminal size. This update should allow it to work on most operating systems and does
# speed up the autosize feature quite a bit – though it still slows things down quite a bit. 
# For more robust features, it's recommended you use a progress bar library like tdqm (see: https://github.com/tqdm/tqdm) 

def printProgressBar (iteration, total, prefix = '', suffix = '', decimals = 1, length = 100, fill = '█', autosize = False):
    """
    Call in a loop to create terminal progress bar
    @params:

    percent = ("{0:." + str(decimals) + "f}").format(100 * (iteration / float(total)))
    styling = '%s |%s| %s%% %s' % (prefix, fill, percent, suffix)
    if autosize:
        cols, _ = shutil.get_terminal_size(fallback = (length, 1))
        length = cols - len(styling)
    filledLength = int(length * iteration // total)

# Sample Usage
import shutil, time

# A List of Items
items = list(range(0, 57))
l = len(items)

# Initial call to print 0% progress
printProgressBar(0, l, prefix = 'Progress:', suffix = 'Complete', autosize = True)
for i, item in enumerate(items):
    # Do stuff...
    time.sleep(0.1)
    # Update Progress Bar
    printProgressBar(i + 1, l, prefix = 'Progress:', suffix = 'Complete', autosize = True)

@ezequias As I understand it, this issue has to do with the return character for the printProgressBar function. It's set to \r but you should be able to set it to \r\n or \n to make it work. The upshot is that your IDE handles the return and newline characters differently than the terminal the function was developed in.

OK man. No prob. Em seg, 7 de out de 2019 às 16:49, Greenstick <notifications@github.com> escreveu:
