Should I install Anaconda (or miniconda) Python?

My .cshrc file is not changed. The only changed file is .bash_profile
(see 3).
When I start a new terminal, it comes with anaconda environments.
So maybe I have to comment the .bash_profile?
Do you use .cshrc or .bashrc file?
Do those "the code between >>> conda initialize and <<<< conda
initialize" appear in your .cshrc or .bashrc file or other file?
Thanks
