You need to use "\\" double backslash everywhere where ever you need only a single backslash.
In dictionary key as well as while providing input.

syntaxes={
        '>':"greater than",
        "<": "less than",
        "*": "multiplication",
        "+": "addition",
        '/': "forward slash",
        '\\': "back slash" # String literal is unterminatedPylance

    }
input='\\'
print(syntaxes[input])
