Loading bar in Python 3.x

I want to make a loading bar like inapton thelinuxwhen downloading package files or installing them.
There somehow it is necessary to erase the lines, I was looking for this, but many scripts did not work for some reason.

those. loading is displayed in one line? And this line keeps changing

    try this

    import time
from progress.bar import IncrementalBar
mylist= [1,2,3,4,5,6,7,8]
bar= IncrementalBar('Countdown', max= len(mylist))
for item in mylist:
    bar.next()
    time.sleep(1)
bar.finish()

    Personally, I do this (not using modules):

    import time
for percent in range(100):
    s= f"[{(percent //10) * '■'}"
    s += f"{(10 -(percent //10)) * '○'}]"
    s += f"{percent}"
    print(s, end="\r")
    time.sleep(0.1)
>>> [■■■■■■■○○○] 78

    s is broken into lines to make it easier to read. In fact, everything can be collected in one line

    The code is not mine, but stolen from the Internet, which I use. Without additional libraries 1 function

    import time
def printProgressBar(iteration, total, prefix= '', suffix= '', decimals= 1, length= 100, fill= '█', printEnd= "\r"):
    """
    Call in a loop to create terminal progress bar
    @params:
        iteration -Required : current iteration (Int)
        total -Required : total iterations (Int)
        prefix -Optional : prefix string (Str)
        suffix -Optional : suffix string (Str)
        decimals -Optional : positive number of decimals in percent complete (Int)
        length -Optional : character length of bar (Int)
        fill -Optional : bar fill character (Str)
        printEnd -Optional : end character (e.g. "\r", "\r\n") (Str)
    """
    percent= ("{0:." + str(decimals) + "f}").format(100 * (iteration /float(total)))
    filledLength= int(length * iteration //total)
    bar= fill * filledLength + '-' * (length -filledLength)
    print('\r%s |%s| %s%% %s' % (prefix, bar, percent, suffix), end= printEnd)
    #Print New Line on Complete
    if iteration== total:
        print()
#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', length= 50)
for i, item in enumerate(items):
    # Do stuff...
    time.sleep(0.1)
    # Update Progress Bar
    printProgressBar(i + 1, l, prefix= 'Progress:', suffix= 'Complete', length= 50)
