Now create new xcode project  File > New > Project > Cross-platform > External Build System > Next Enter Name and  Enter a name (e.g. PythonLearning), and enter the path from  above Step(i.e  /usr/local/bin/python3 ) into the “Build Tool” line. Click Next.  Create a Python file Choose File > New, select macOS > Other &g
