간단하고 사용자 정의 가능한 진행률 표시 줄

아래에는 정기적으로 사용하는 많은 답변이 있습니다 (수입 필요 없음).

샘플 사용법

import 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', 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)

샘플 출력 :

Progress: |█████████████████████████████████████████████-----| 90.0% Complete

진행률 표시 줄을 터미널 창 너비에 맞게 동적으로 조정할 수있는 옵션에 대한 주석에서 설명이있었습니다. 권장하지는 않지만 이 기능을 구현 하는 요점 은 다음과 같습니다.
