Start with Python

Short list Python information

Introduction to Python

To start

  • There are two popular versions of Python (2.7 and 3.5);

  • Ide $\rightarrow$ Pycharm, Netbeans, Eclipse etc, I suggest Spyder (similar to Rstudio);

  • Jupyter Notebook $\rightarrow$ web application to create and share documents (code, formulas, text, etc);

  • Anaconda $\rightarrow$ contains R, Python, various IDE, Anaconda navigator (GUI), Anaconda Prompt and Jupyter Notebook.

Some tutorials

Some basic information

  • Python uses white space to identify code blocks (Avoid using tabs and prefer whitespaces) $\rightarrow$ $4$ spaces per indentation level;
  • No $;$ at the end of each line;
  • No variable declaration as R;
  • assignment operator $=$, i.e not <-.

Some useful packages

Install packages

  • Anaconda Prompt $\rightarrow$ Example:

    conda install -c conda-forge numpy
  • Anaconda Navigator $\rightarrow$ enviroments $\rightarrow$ search package

In both cases, it is useful to create an enviroments:

conda create -n yourenvname python=x.x anaconda
activate yourenvname

and then install packages into yourenvname.
