Makefiles are a simple way to organize code compilation. Typically they are used in writing C programs to ease all stuff that needs to be done before code can be used as a program. You can specify rules to tell make how to compile your programs. you compile C code using gcc. How is this even connected with python?
Likewise, what is in a Makefile?
A makefile is a special file, containing shell commands, that you create and name makefile (or Makefile depending upon the system). The makefile contains a list of rules. These rules tell the system what commands you want to be executed. Most times, these rules are commands to compile(or recompile) a series of files.
Additionally, what is make command? The makefile is read by the make command, which determines the target file or files that are to be made and then compares the dates and times of the source files to decide which rules need to be invoked to construct the target. Often, other intermediate targets have to be created before the final target can be made.
Hereof, why do we use Makefile?
A makefile is useful because (if properly defined) allows recompiling only what is needed when you make a change. A makefile store a list "input" files, "output" files and "commands" needed to produce the output given the input.

The make utility requires a file, Makefile (or makefile ), which defines set of tasks to be executed. You may have used make to compile a program from source code. Most open source projects use make to compile a final executable binary, which can then be installed using make install .What is a Makefile in C?
Makefile is a set of commands (similar to terminal commands) with variable names and targets to create object file and to remove them. In a single make file we can create multiple targets to compile and to remove object, binary files. You can compile your project (program) any number of times by using Makefile.How do you create a Makefile?

- Edit source files.
- Run make: All you need to do is run the program from the command line without any arguments. % make.

What is a make target?
A 'make target' is basically a file that you want rebuilt. However, some makefiles do not specify any target; then you must specify one on the command line. Or, if you don't want the default target built, then you must specify the target that you do want built. A target can also be 'phony', in the terms of GNU make.Does Python need a Makefile?
This programming language is compiled itself while invoked so it doesn't need any makefiles to work. As I said in the beginning in python projects you can ease your life and save a lot of keystrokes using makefile.Does Python open Create file?
Python has a built-in function open() to open a file. This function returns a file object, also called a handle, as it is used to read or modify the file accordingly. We can specify the mode while opening a file. In mode, we specify whether we want to read 'r' , write 'w' or append 'a' to the file.What is a Makefile in C++?
A makefile is a file containing instructions for how to atomically build your program. If you have a makefile named makefile you should only have to run the make command (without arguments) to build the program.

So it's likely that the makefile contains Space at the beginning of rule stanzas within the file.What is a Makefile in Linux?
Makefile is a program building tool which runs on Unix, Linux, and their flavors. It aids in simplifying building program executables that may need various modules. To determine how the modules need to be compiled or recompiled together, make takes the help of user-defined makefiles.What does sudo make install do?
