What are Computer Programming
Languages?
• Computer programming languages allow us to give
instructions to a computer in a language the
computer understands.
• Just as many human-based languages exist, there
are an array of computer programming languages
that programmers can use to communicate with a
computer.

Languages?
The portion of the language that a computer can
understand is called a “binary.” Translating
programming language into binary is known as
“compiling.”
Each language, from C Language to Python, has its
own distinct features, though many times there are
commonalities between programming languages.

Languages?
• These languages allow computers to quickly and
efficiently process large and complex swaths of
information.
• For example, if a person is given a list of
randomized numbers ranging from one to ten
thousand and is asked to place them in
ascending order, chances are that it will take a
sizable amount of time and include some errors.

What makes learning it important?
Python lets you work quickly to integrate systems as a
scripting or glue language. It’s also suited for Rapid
Application Develop (RAD).

implemented in Python.NASA uses Python in its Integrated
Planning System as a standard scripting language.
