Normal progress bar

You can perform statistical calculations during code iteration and use formatted strings to output the code running progress.

import sys
import time
for i in range(1, 101):
    print("\r", end="")
    print("下载进度{}%: ".format(i), "\33[1;91;43m▋\33[1;32;0m" * (i // 2), end="")
    sys.stdout.flush()
    time.sleep(0.05)

  

With time progress bar

import time
scale = 50
start = time.perf_counter()
for i in range(scale + 1):
    a = "\33[1;91;101m▋\33[1;32;0m" * i
    b = " " * (scale - i)
    c = (i / scale) * 100
    dur = time.perf_counter() - start
    print("\r下载进度{:^3.0f}% {}{} {:.2f}s".format(c, a, b, dur), end="")
    time.sleep(0.05)

  

progress progress bar

You only need to define the number of iterations, the type of progress bar and inform the progress bar during each iteration.

Official: https://pypi.org/project/progress

import time
from progress.bar import IncrementalBar
from progress.bar import Bar

i = 10
# bar = IncrementalBar('进度', max=1)
bar = Bar('进度', max=i, fill='\33[1;91;101m❤ \33[1;32;0m', suffix='%(percent)d%%')
for item in range(10):
    bar.next()
    time.sleep(1)
    bar.finish()

  

alive_progress progress bar

This progress bar has some animation effects. Related documents: https://github.com/rsalmei/alive-progress

import time
from alive_progress import alive_bar

items = range(100)
with alive_bar(total=len(items)) as bar:
    for item in items:
        bar()
        time.sleep(0.1)

PySimpleGUI graphical progress bar

import PySimpleGUI as sg
import time

num = 100
for i in range(num):
    sg.one_line_progress_meter('任务下载进度', current_value=i, max_value=num, key='完成！', no_button=True, keep_on_top=True)
    time.sleep(0.1)
