I am trying to start a torrent downloader in windows, which is executed from the command prompt. It takes in a command such as torrent "magnet_link". The problem I'm having is when I start the command from python using os.system("start /wait cmd /c torrent " + '"' + link + '"') for some reason the " character is not shown in the command prompt window launched, making the command useless. The response I am getting is: 'dn' is not recognized as an internal or external command,
operable program or batch file.

Use can use built-in str.center:
link = 'http://stackoverflow.com'
print("start /wait cmd /c torrent %s" % link.center(len(link)+2, '"'))
# start /wait cmd /c torrent "http://stackoverflow.com"

os.system("start /wait cmd /c torrent \"\"".format(link))
What happens:
