• Operations with strings
• Pattern matching with regular expressions
• Web scrapping (requests, urllib, Beautiful Soup)
• Data Serialization (simplejson and pickle)
• Input/Output (file-systems and database systems)
• Multi-Threading
• Multi-Processing
• Asyncio
• Using Celery[Redis] for batch processing
• Getting started with Numpy, Pandas
• Visualization with Matplotlib
• Word cloud diagrams

• Data preparation and acquisation
• Data assessment and cleaning
• Data aggregation
• Exploratory Data Analysis

• Example (statistical) model (Keras/Tensorflow/Scikit-learn)

• Getting started with NLTK, Spacy, TextBlob, Polyglot, CoreNLP, Gensim

Python Environment Setup

$ denotes terminal input
>>> denotes input within python environment
In [n]: denotes input within ipython environment

Packages update and ugrade

$ sudo apt update && sudo apt upgrade -y

build dependancies

$ sudo apt install build-essential software-properties-common -y sudo apt install libncurses5-dev libgdbm-dev libnss3-dev libssl-dev libreadline-dev libffi-dev wget libsqlite3-dev sqlite3 -y

If you are on Debian, then you need to install zlib.

$ sudo apt install zlib1g-dev -y

Download preferred python flavor source tarball.

$ wget https://www.python.org/ftp/python/3.7.4/Python-3.7.4.tgz
Alternatively
$ curl -O https://www.python.org/ftp/python/3.7.4/Python-3.7.4.tgz

Unzip the tarball.

$ tar -xzvf Python-3.7.4.tgz

Configure the build the source.

$ cd Python-3.7.4
$ ./configure --enable-optimizations

Build the binaries and install

$ make -j n #where n is the number of processor cores
$ sudo make altinstall #Do not use the standard make install as it will overwrite the default system python3 binary.

On terminal type

$ python3.7

Alternatively, Install from ppa repositories (No build issues)

$ sudo add-apt-repository ppa:ubuntu-toolchain-r/ppa
$ sudo apt install python3.7

Alter python command for the signed-in user. Can be done for all users (It's not recommended changing global python command for there might be OS packages dependancy on python2.7)

$ nano ~/.profile

Add the following two lines in your ~/.profile script:

alias python=python3.7
alias pip=pip3

Close terminal and re-open it
On the newly opened terminal type

$ python

Using python built-in -m venv command

$ python3 -m venv myvenv

Activate the environment

$ source myvenv/bin/activate

Install package into the environment

$ pip install simplejson ipython

Run (python) code from the environment

$ python
>>> from simplejson import loads
>>> print('hello world')

Output:

hello world

Run above code from ipython environment

$ ipython
In [1]: from simplejson import loads
In [2]: print('hello world')

Output:

hello world

$ pip3 install virtualenv

Now create a virtual environment

$ virtualenv -p python3.7 venv

Create virtual environment with system site packages

$ virtualenv --system-site-packages -p python3.7 venv

Activate and use the environment

$ source venv/bin/activate

$ pip3 install virtualenvwrapper
$ mkdir ~/.virtualenvs
$ nano ~/.profile

Add the following lines in your ~/.profile script:

export WORKON_HOME="$HOME/.virtualenvs"
VIRTUALENVWRAPPER_PYTHON='/usr/bin/python3.7' #This needs to be placed before the virtualenvwrapper command
source /usr/local/bin/virtualenvwrapper.sh

Execute below command to complete setup

source ~/.profile

Exit the terminal and open a new window
In the newly opened terminal window, type these commands to create virtual environments within virtualwrapper

mkvirtualenv testvenv
mkvirtualenv anothervenv
deactivate
workon
workon testvenv rmvirtualenv anothervenv

Install Git

$ sudo apt install git

Configuring Git

$ git config --global user.name "Your Name"
$ git config --global user.email "[email protected]"

Verify the changes

$ git config --list

Create project virtual environment

$ mkvirtualenv nlpcrash

Install project dependancy packages

$ pip install -r requirements.txt
