Install as:

pyenv install 3.10.3

Set as default

pyenv global 3.10.3

Add to the path (.zshrc or .bashrc)

export PYENV_ROOT="$HOME/.pyenv"
export PATH="$PYENV_ROOT/shims/:$PATH"

Reload the terminal and check

❯ python3 -V
Python 3.10.3

Check if the following works

❯ cat test.py
from terra_sdk.client.lcd import LCDClient
from terra_sdk.key.mnemonic import MnemonicKey

mk = MnemonicKey(mnemonic='notice oak worry limit wrap speak medal online prefer cluster roof addict wrist behave treat actual wasp year salad speed social layer crew genius')
terra = LCDClient("https://lcd.terra.dev", "columbus-5")
wallet = terra.wallet(mk)
print(wallet.key.acc_address)

❯ python3 test.py
terra1x46rqay4d3cssq8gxxvqz8xt6nwlz4td20k38v

If works, send @Vritra4 a hug ❤️ !
