need suggestion for me choosing best online training platform for data science with python
Are you looking for free or a paid training platform?
Jupyter is a great platform for reproducible research and training in data science.
There are over 10 Million Jupyter notebooks mostly in Python searchable on github.
The Python Data Science Cookbook. https://github.com/jakevdp/PythonDataScienceHandbook
There are great videos on YouTube (I really like PyCon or JupyterCon)
Let me know if that helps.
