Received error after entering 'brew doctor'

Question

I'm new to programming and this question may seem pretty easy...so please bear with me.

After I entered 'brew doctor' in the terminal, instead of prompting something like 'Your system is ready to brew', I got the following:

Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don't worry or file an issue; just ignore this. Thanks!

Warning: "config" scripts exist outside your system or Homebrew directories.
`./configure` scripts often look for *-config scripts to determine if
software packages are installed, and which additional flags to use when
compiling and linking.

Having additional scripts in your path can confuse software installed via
Homebrew if the config script overrides a system or Homebrew-provided
script of the same name. We found the following "config" scripts:
  /Library/Frameworks/Python.framework/Versions/3.8/bin/python3-config
  /Library/Frameworks/Python.framework/Versions/3.8/bin/python3.8-config
  /Library/Frameworks/Python.framework/Versions/3.6/bin/python3.6m-config
  /Library/Frameworks/Python.framework/Versions/3.6/bin/python3-config
  /Library/Frameworks/Python.framework/Versions/3.6/bin/python3.6-config

From my shallow understanding, am I supposed to delete one of the python versions or keep both and enter another command to resolve this issue? Thanks in advance!

Homebrew is telling you that the 5 files:

/Library/Frameworks/Python.framework/Versions/3.8/bin/python3-config
/Library/Frameworks/Python.framework/Versions/3.8/bin/python3.8-config
/Library/Frameworks/Python.framework/Versions/3.6/bin/python3.6m-config
/Library/Frameworks/Python.framework/Versions/3.6/bin/python3-config
/Library/Frameworks/Python.framework/Versions/3.6/bin/python3.6-config

are not installed by Homebrew and can confuse him. If you don't use Python versions installed outside Homebrew, you can delete these files and the brew doctor command should again display:

Your system is ready to brew.
