Set Anaconda as default python on macOS Catalina

I am currently making my first steps with Python and try to get Anaconda running on my mac (macOS Catalania 10.15) as my default option for python. When I type "python" in my terminal though, it is still Python 2.7 that is showing up.

I found out that in order to run anaconda as a default, I need to customize my .bash_profile. But as it seems, anaconda is already set there:

# >>> conda initialize >>>
# !! Contents within this block are managed by 'conda init' !!
__conda_setup="$('/opt/anaconda3/bin/conda' 'shell.bash' 'hook' 2> /dev/null)"
if [ $? -eq 0 ]; then
    eval "$__conda_setup"
else
    if [ -f "/opt/anaconda3/etc/profile.d/conda.sh" ]; then
        . "/opt/anaconda3/etc/profile.d/conda.sh"
    else
        export PATH="/opt/anaconda3/bin:$PATH"
    fi
fi
unset __conda_setup
# <<< conda initialize <<<

I found this question that seems to solve the same problem, but I am not sure how to apply the solution of it to my problem. A comment there states, that starting with macOS 10.15 I need to change the .zprofile. Unfortunately, I can't find the file.

Catalina by default runs zsh, which you can confirm with echo $0. The file you changed works for bash.

Copy the following anaconda init lines to .zshrc and you should be good to go:

__conda_setup="$('/opt/anaconda3/bin/conda' 'shell.zsh' 'hook' 2> /dev/null)"
if [ $? -eq 0 ]; then
    eval "$__conda_setup"
else
    if [ -f "/opt/anaconda3/etc/profile.d/conda.sh" ]; then
        . "/opt/anaconda3/etc/profile.d/conda.sh"
    else
        export PATH="/opt/anaconda3/bin:$PATH"
    fi
fi
unset __conda_setup

The only difference with respect to your file is replacement of shell.bash with shell.zsh.

Most commonly, the installation is fine but you can't see that until you refresh your terminal window. Just close it and open a new one.
