Python is a high level language based on C.

Python is:

  • named after Monty Python's Flying Circus.
  • case-sensitive.

Python evaluates (finds the value of) the expression it is given and prints the value which is handy for interactive programming.

Python is an object-oriented programming language. In Python everything is an object.

Why learning Python ?

Python is used:

  • a lot of data mining and machine learning library
  • Data Science (Lexical Analysis, Nltk, …)
  • VM Virtual Box Api

The Zen of Python, by Tim Peters

  • Beautiful is better than ugly.
  • Explicit is better than implicit.
  • Simple is better than complex.
  • Complex is better than complicated.
  • Flat is better than nested.
  • Sparse is better than dense.
  • Readability counts.
  • Special cases aren't special enough to break the rules.
  • Although practicality beats purity.
  • Errors should never pass silently.
  • Unless explicitly silenced.
  • In the face of ambiguity, refuse the temptation to guess.
  • There should be one– and preferably only one –obvious way to do it.
  • Although that way may not be obvious at first unless you're Dutch.
  • Now is better than never.
  • Although never is often better than *right* now.
  • If the implementation is hard to explain, it's a bad idea.
  • If the implementation is easy to explain, it may be a good idea.
  • Namespaces are one honking great idea – let's do more of those!
