你必须做三件事：

• 将进度条状态存储在一个单独的对象中，你可以在不同的循环中调用方法来更新进度条状态。
• 打印进度条时，确保不打印换行符
• 打印控制台输出时，先清除当前行，打印后重新绘制条形图。

你可以稍微涵盖前两个，但不包括第三个。最好将控制台的控制封装在一个类中，这个类也可以管理进度条，这样它就可以在一个位置处理清除、打印和重新显示：

import builtins
import math
import sys
import threading

class ProgressConsole:
    def __init__(self, size, width=80, output=sys.stdout):
        self.size = size
        self.width = width
        self.current = 0
        self.output = output
        # [...] and space take 3 characters, plus max width of size (log10 + 1)
        self._bar_size = width - 4 - int(math.log10(size))
        self._bar_step = self._bar_size / self.size
        self._lock = threading.Lock()

    def print(self, *message):
        with self._lock:
            self._clear()
            builtins.print(*message, file=self.output)
            self._display()

    def increment(self, step=1):
        with self._lock:
            self.current = min(self.current + step, self.size)
            self._display()

    def _clear(self):
        self.output.write('\r')
        self.output.write(' ' * self.width)
        self.output.write('\r')

    def _display(self):
        bar = '#' * int(round(self._bar_step * self.current))
        blank = ' ' * (self._bar_size - len(bar))
        self.output.write(f"\r[{bar}{blank}] {self.current}")

我在示例代码导入threading时包含了一个线程锁，因此我假设您希望能够在这样的环境中使用它。
上面的类使用固定宽度的进度条，在返回到最左边的列\r之前，通过写出一系列空格来清除进度条。
我还将条形图设置为固定宽度，以便它从左到右填充，而不是在屏幕上扩展。
然后确保你'打印'到这个对象：

if __name__ == "__main__":
    progress_bar = ProgressConsole(10)
    print = progress_bar.print  # replace built-in with our own version

    print("Starting in main...")
    progress_bar.increment()
    print("\nOther print statement here.")
    print("Nice day, expensive day.")
    progress_bar.increment(2)

    doThis()
    progress_bar.increment()
    doThat()
    progress_bar.increment()
    doThis()
    doThat()
    progress_bar.increment(2)
    doThat()
    doThat()
    progress_bar.increment()
    wrapUp()
    progress_bar.increment(2)

上面的最终输出是：

Starting in main...
