PYTHONPATH really messed up, hoping to fix without wiping computer

I'm still figuring out how to set environment variables and paths and such, so this was bound to happen I suppose, But before trying to get started with python, I didn't know it already came installed on Ubuntu 20.04. So I tried installing it more than once. Consequently, my pythonpath is completely messed up and even with help (from someone unfamiliar with ubuntu) I couldn't get it untangled. I'm not really sure what to do now and would appreciate some help!

Here is what the output from my terminal gives me using various commands to find my pythonpath: terminal window

I've tried fixing it in the past but with no luck, and honestly can't remember what I've tried.

Here is my /etc/environment paths: PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin"

My ~/.bashrc:

# ~/.bashrc: executed by bash(1) for non-login shells.
# see /usr/share/doc/bash/examples/startup-files (in the package bash-doc)
# for examples

# If not running interactively, don't do anything
case $- in
    *i*) ;;
      *) return;;
esac

# don't put duplicate lines or lines starting with space in the history.
# See bash(1) for more options
HISTCONTROL=ignoreboth

# append to the history file, don't overwrite it
shopt -s histappend

HISTSIZE=1000
HISTFILESIZE=2000

# check the window size after each command and, if necessary,
# update the values of LINES and COLUMNS.
shopt -s checkwinsize

# If set, the pattern "**" used in a pathname expansion context will
# match all files and zero or more directories and subdirectories.

You can see the commented lines at the bottom here where I previously tried to fix the path with no luck.

My ~/.bash_profile:

export ANDROID_SDK=/home/user/Android/Sdk
export PATH=/home/user/Android/Sdk/platform-tools:/home/user/Android/Sdk:/home/user/.local/bin:/home/mark/.local/bin:/home/user/.nvm/version>
export PATH=$PATH:$(yarn global bin)
export ANDROID_HOME=$HOME/Android/Sdk

export PATH=$PATH:$ANDROID_HOME/tools
export PATH=$PATH:$ANDROID_HOME/tools/bin
export PATH=$PATH:$ANDROID_HOME/platform-tools
export PATH=$PATH:/home/user/Android/Sdk/platform-tools

Please let me know what I should do, I'm really eager to fix this asap. And if it comes to wiping my system, I'll do that. That just seems risky and I'd rather not. Thank you!
