您可以通过将命令定义为子进程来解决此问题：

import subprocess

p = subprocess.Popen('sh download.sh', stdout=subprocess.PIPE, shell=True)

(output, err) = p.communicate()  

#This makes the wait possible
p_status = p.wait()

#This will give you the output of the command being executed
print("Command output: " + output)

我想你可以使用“subprocess”和process.wait（）函数。例如：

import subprocess
your_process_name = subprocess.Popen('sh','download.sh')
your_process_name.wait()
