改进一下代码,要求输出上下对其import time def show_progress_bar(percent): bar_length = 30 completed = int(percent * bar_length) remaining = bar_length - completed bar = '[' + '*' * completed + '-' * remaining + ']' print(f'{"=" * 20}开始下载{"=" * 20}') print(f'{percent*100:.0f}%{bar}') time.sleep(0.1) for i in range(101): show_progress_bar(i / 100)

好的,以下是改进后的代码,输出的进度条将会上下对齐:
```python
import time
def show_progress_bar(percent):
bar_length = 30
completed = int(percent * bar_length)
remaining = bar_length - completed
bar = '[' + '*' * completed + '-' * remaining + ']'
progress_info = f'{percent*100:.0f}% {bar}'
padding = ' ' * (60 - len(progress_info))
print(f'{"=" * 20}开始下载{"=" * 20}')
print(f'{progress_info}{padding}', end='\r')
time.sleep(0.1)
# 示例代码的使用方法
for i in range(101):
show_progress_bar(i / 100)
print('\n下载完成!')
```
在这个代码中,我们增加了一个 `padding` 变量,用于在进度条后面填充空格,使得进度条的输出总长度为 60,这样就可以实现上下对齐的效果了。同时,使用 `\r` 控制符使得输出时光标回到行首,从而实现动态更新进度条的效果。
这样,当下载完成时,最后一行的输出是 `下载完成!`,而进度条不会遮挡它。
