error on bat file

[Sanlus]

so today i tried to create a bat file, and the code is like this:

#! python3
@py.exe C:\Users\MSI\AppData\Local\Programs\Python\Python37-32\Automate the Boring Stuff with Python Course\searchmap.py %*

and the system popped out a SyntaxError box saying invalid syntax, highlighting the C in C:\ part. i tried to get rid of first line or change the @py.exe to just @py but nothing is working.
