Python Programming Language
•
Python is a high-level programming language developed by
Guido van
Rossum
back in
1985-1990
•
it was designed to be
highly readable:
it is one of the easiest
programming languages to start with
Python Programming Language
•
Python
is the
#1
programming language
mainly because of scientific computing and
machine learning
•
there are a huge number of
libraries
you can
rely on
–
SciPy, SkLearn or Keras
•
data science
and artificial intelligence related
applications rely extremely heavily on Python
•
most of the
scientific community
use Python
–
physics simulations, complex networks etc.
Python Programming Language
•
Python is an
interpreted programming language
•
it means that the code is interpreted and processed at run-time:
there is no need for compiling the program
•
it is and
object oriented
programming language: it may encapsulate
code within give classes and objects

Data Types in Python
Variables
are basically containers for storing data: they are reserved
memory locations
to store values
→
a variables is created the moment you first
assign a value
to it
(in other programming languages we have to declare it)
→
the data stored in the memory can be of many types. There
