要在Python中实现实时计时,可以使用time模块中的time函数。首先,使用`import time`导入time模块。然后,在需要计时的代码段前后分别调用`time.time()`函数来获取当前时间,将其保存在变量start_time和end_time中。最后,计算时间差(end_time - start_time)并打印出来作为程序运行的时间。以下是一个示例代码:
```python
import time
start_time = time.time()
# 执行代码
end_time = time.time()
print("程序运行时间:", end_time - start_time, "秒")
```
这段代码使用time模块中的time函数实现了实时计时功能。在代码执行前后分别调用time.time()函数获取当前时间,并将其保存在start_time和end_time变量中。计算时间差(end_time - start_time)并打印出来作为程序运行的时间。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
