1.python-dev or Python-devel
Python-dev or python-devel is called the Python development package, which includes information such as the header files that were written with the Python extensions compiled with c/java/c#. For example, when we compile a Python extension module in C language, because there will be such statements as #include<python.h>, we need to install the Python-devel development package first.
2. Various *.devel Development Kits
Linux programming, you will also encounter a variety of *-devel development packages, such as Mysql-devel, Libgtk+-devel, and so on. The *-devel development package consists primarily of header files and static link libraries. Any *-devel package is basically like this.
Note:
Note that Python-dev or other *.devel software is generally written in C language of some header or CPP files, often other modules or this our own written module at compile time, we need to rely on these *-devel software packages
