SyntaxError when expression has "lambda" or λ

[heyeshuang]

Hello, when I tried to run

py2tex("(V)*((lambda)**(-q))")

It threw a SyntaxError: invalid syntax.

I think it might because lambda is a reserved word of python.

@emetor did you encounter this too ?

Yes, I can confirm!
'lambda' is not a valid identifier in Python so you can use 'lbd' instead.

py2tex("(V)*((lbd)**(-q))")
$$V {\lambda}^{-q}$$

Okay, then the unicode_tbl dict may also need to be changed. See

"λ": "lambda",

Thank you very much @heyeshuang for pointing this out. It is now fixed (also lambda).
