Filenotfounderror: [winerror 2] The System Can't Find The Specified File

I'm currently learning how to use the module subprocess and I just started with my new book. Instantly, I got an error message which I don't understand. Traceback (most recent call

Solution 1:

echo is not a program that can be executed but it’s a shell command available in the Windows command line interpreter cmd.exe.

In order to execute shell commands, you need to pass shell=True to Popen:

proc = subprocess.Popen(['echo', 'Hello there'], stdout=subprocess.PIPE, shell=True)
#                                                                        ^^^^^^^^^^
