MATLAB to Python?

[MATLABdude]

Hi!

Can you, please, try to help me with Python? I try to convert a MATLAB
program to Python.

Here are the MATLAB codes:

Here is my Python code:

What is wrong with my Python code? The program doesn't produce quite
the same lambdas as the MATLAB program does. My code probably has lots
of errors because I'm just learning the basics about Python.

Thanks for all the help!
