When I run a python application on Mac, it shows many dialogs about want "Python.app" to accept incoming network connections.
Even I Allow it many times, it shows again and again.
How to allow it one time and not show any more?
I found this question: Add Python to OS X Firewall Options?
I followed the accepted answer to do but finally when I run codesign -s "My Signing Identity" -f $(which python), it said:
/usr/bin/python: replacing existing signature
error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/codesign_allocate: can't create output file: /usr/bin/python.cstemp (Operation not permitted)
/usr/bin/python: the codesign_allocate helper tool cannot be found or used
How to do next?

But if you use a laptop and hop onto untrusted networks frequently, you should enable the firewall. macOS also includes an assortment of shared network services to remotely access your content. If you keep those services enabled or use third-party apps, that could make your Mac vulnerable to a network attack.
With the OS X firewall enabled, you can remove the "Do you want the application "python" to accept incoming network connections?" message.
