How can I surpass "Press any key to continue ..." in python?

In my project I am starting a .bat file from a python script. Just like this:

os.system("testfile.bat")

When this `testfile.bat is finished it ends with the prompt Press any key to continue .... I would like my python script to surpass this prompt and somehow simulate the keypress.

How can I achieve that? I already implemented this functionality by using a subprocess but as it turned out a subprocess is not suited for the context of my project (has something to do with printing to the console). Any ideas?

If you have "pause" at the end of your Bat file just remove it, it will continue executing the rest of python script after the subprocess is done. 

p = subprocess.Popen("testfile.bat", shell=False, \
                          cwd=path_to_exe)

p.wait()

Add >nul to the end of the pause commend (In the batch file.) it will not print "Press any key to continue.

Using the subprocess module is always suited and superior to os.system.

Just do

sp = subprocess.Popen("testfile.bat", stdin=subprocess.PIPE)
sp.stdin.write("\r\n") # send the CR/LF for pause
sp.stdin.close() # close so that it will proceed

and you should be done.
