Debian / Ubuntu: Fatal error: Python.h: No such file or Directory

I am trying to install 3rd party python apps using pip command and getting the following error:

gcc -pthread -fno-strict-aliasing -fwrapv -Wall -Wstrict-prototypes -fPIC -std=c99 -O3 -fomit-frame-pointer -Isrc/ -I/usr/include/python2.7 -c src/MD2.c -o build/temp.linux-x86_64-2.7/src/MD2.o

src/MD2.c:31:20: fatal error: Python.h: No such file or directory

compilation terminated.

error: command 'gcc' failed with exit status 1

Where can I find Python.h file and how do I fix this problem under Debian or Ubuntu Linux sever based system?

Python.h is nothing but a header file. It is used by gcc to build applications. You need to install a package called python-dev. This package includes header files, a static library and development tools for building Python modules, extending the Python interpreter or embedding Python in applications. To install this package, enter:

For Python version 2.x+

$ sudo apt-get install python-dev
# apt-get install python-dev

For Python version 3.x+

$ sudo apt-get install python3-dev
# apt-get install python3-dev
Sample outputs (for my python 2.x):
