   The "apt-get install" command tells the computer to install the package "build-essential" which is required to install Python. sudo apt-get install libreadline-gplv2-dev libncursesw5-dev libssl-dev libsqlite3-dev tk-dev libgdbm-dev libc6-dev libbz2-dev These are programs that Python uses to run correctly.
   
   They are also known as “dependencies”. , Use the following command: cd ~/Downloads/ The "cd" command changes to the correct working directory so the computer can find and put programs in the right place. wget http://python.org/ftp/python/2.7.5/Python-2.7.5.tgz , This time, we change to the newly created Python directory. , It will alert you of any critical errors. ./configure , It compiles the source code and creates the executables. make , With the following command, all of the applications and libraries associated with Python are moved into the correct places on your computer. sudo make install , Any text editor that can save files with a ".py" extension will do.
