Now I’m trying to learn about pandas package in python.
but using rename function, I have some problem.

i would like to apply structural break test in python, so here is my colab page structure :

After doing some research, this website seems like a reliable source on Statistics in python
https://realpython.com/python-statistics/#:~:text=Python’s%20statistics%20is%20a%20built,%2D%20and%20multi%2Ddimensional%20arrays.
however the plotly library came up while in my research and it wasnt mentioned in the aformentioned resource. where does plotly fit into the python statistic’s ecosystem when compared to the libraries covered in the resource? in otherwords where does plotly stand when compared to
python’s statistics library
numPy
pandas
matplotlib
Scipy

I want to use a mathematical model of this kind. How do I find the exact integral form of cdf(x) which Python uses in this context?
