Why does cmdLine.run('clear') give me an error?

Question

I am trying to learn to use espeak and I am following a tutorial, but I am stuck on the very first step. When I try to run this python code:

import subprocess as cmdLine
cmdLine.run("clear")

speech = 'This is what we want espeak to say'

command = 'espeak -x -v ' + 'mb-us1 ' + chr(34) + speech + chr(34)
print (command)
print ("")

All I'm getting is:

PS C:\Users\lukas\New folder> & C:/Users/lukas/AppData/Local/Microsoft/WindowsApps/python3.10.exe "c:/Users/lukas/New folder/hello.py"
Traceback (most recent call last):

    hp, ht, pid, tid = _winapi.CreateProcess(executable, args,

I don't understand what's wrong. All I want is to get cmdLine.run('clear') to work.
