1. Defining Command PackagesIf some of the same sequence of commands appear in Makefile, you can define a variable for these same command sequences. The syntax for defining this sequence of commands begins with "define" and ends with "endef", such

  in Python, variable lookup follows the LGB principle of prioritizing a variable in a local scope (regional scope), failing to find it in the global scope, and finally attempting to build the scope again (build-in Scope), and throws an exception if

Using variables————The variable defined in makefile, like a macro in the C + + language, represents a text string that, when executed in makefile, automatically expands to the original mode as it is used. It differs from C/s + + in that you can

ProfileWe always define functions and variables in the program, and then use these functions and variables to build our system.However, for the interpreter, how and where did it find the data (functions, variables)? What happens inside the
