python 实现各种进度条

1. 时间进度条

class Tiao(object):

    def __init__(self):

        self.obj1 = datetime.timedelta(seconds=1)

        self.var = '%H:%M:%S'

    def add(self, var):

        a = datetime.datetime.strptime(var, self.var)

        b = a + self.obj1

        return str(b.strftime(self.var))

    def str_time(self, var3):

        a, b, c = [int(i) for i in var3.split(":")]

        a *= 3600

        b *= 60

        return a + b + c

    def yuan(self, var1, var2):

        """

        计算 百分比

        :param var1: 现在时间

        :param var2: 总时间

        """

        var1 = self.str_time(var1)

        var2 = self.str_time(var2)

        return '{:.2%}'.format(var1/var2)

def zhanshi(var):

    a = Tiao()

    b = "00:00:00"

    while True:

        if var == b:

            break

        b = a.add(b)

        print('\r%s/%s (%s)' % (b, var, a.yuan(b, var)), end='')

        time.sleep(1)

zhanshi("00:25:37")

# 结果

00:01:39/00:25:37 (6.44%)

2. # 号进度条

        # 2. 根据 现在百分比计算

        well_num = int(percentage / self.a)

        # print("well_num: ", well_num, percentage)

        # 3. 打印字符进度条

        progress_bar_num = self.progress_bar(well_num)

        # 4. 完成的进度条

        return '[%s%s]' % (well_num, space_num)

index = Index()

start = 371

for i in range(start + 1):

    print(index(i, start), end='')

    time.sleep(0.01)

    # \r 返回本行开头

    # end : python 结尾不加任何操作, 默认是空格
