怎么在python3项目中调用dos命令？针对这个问题，这篇文章详细介绍了相对应的分析和解答，希望可以帮助更多想解决这个问题的小伙伴找到更简单易行的方法。
python调用dos命令，使用下面的方法：
os.popen(command)
此方法会阻塞，直到执行完成，当然也会返回执行的结果。如果你使用chcp设置过windows命令行的代码页，比如曾经使用：chcp 65001。那么在执行python程序的时候就可能产生gbk编码的错误，解决此问题需要重新使用：chcp 936来设置命令行代码页就OK了。
完整代码如下：
import os
import shutil

循环执行每个一个资源目录，每个目录的执行过程如下：
1：更新线上目录
2：更新本地目录
3：把本地目录的修改同步到线上目录
4：提交线上目录
