I have used the Differential Evolution genetic algorithm that is in recent versions of scipy to provide initial parameter estimates for curve fitting of Raman spectroscopy data with excellent results. The GitHub project URL is:

Thanks for your advice Zun, Sorry for late response(I was Studying for school test, I am Middle School Student in korea) I will read your docs ASAP. Thanks!

Many Americans, like myself, love the Korean people. I will be glad to help you.

The example code I linked to is for Raman spectroscopy of carbon nanotubes. My background is in nuclear engineering, industrial radiation physics and software engineering. I have worked at POSCO Steel in Pohang many years ago, we measured the steel thickness using gamma and X-ray radiation. The Korean people were very good to me when I was working there.

I have Python code on GitHub for curve fitting and surface fitting with web applications and GUI at https://github.com/zunzun?tab=repositories - the fitted 3D surface equations look really cool.
