# learn R for data science online

## This online Data Science course is structured in understandable & easy progressive steps so that every topic can be easily understood.

## No previous knowledge of Data Science topics is required.

## We start from zero and gradually build up using guided projects with real time data sets.

## While being accessible, the course also introduces you to most of the advanced topics you need when working on Data Science projects.

# Natural Language Processing with Python

**Natural language processing with Python**.

# Python for data science course online

The aim of this post is to provide a quick reference to people who want to learn **Python for Data Science**.As you know, Python is a general purpose programming language and is not specific to data scienceworld.So there will be lot of topics to learn for a beginner.Learning every topic in Python might take considerably long time.

### How to install Python on MacOS

For MacOS, follow the steps given below:

1.Click on Download Python 3.7.0

2.After the python-3.7.0.pkg file gets downloaded, open the installer and follow step by step instructions.

3.Finally you should get the below message, as shown in the screenshot below.

### Where should I write Python code and run it ?

In order to write and run Python , you can use an IDE(**I**ntegrated **D**evelopment **E**nvironment) like **PyCharm** or **IDLE** (**I**ntegrated **D**evelopment and **L**earning **E**nvironment) or **Jupyter Notebook**.

Since we have just started learning , let’s use IDLE, as it is the simplest of these three editors.

To launch IDLE, go to your Python Installation directory, there you will find Lib folder.

Go inside Lib folder and you will find idlelib folder.Double click idle.bat file within idlelib folder and then IDLE will start, like shown in the screenshot below.

Let us declare a variable i ,assign 100 to it and press Enter. The variable i will now contain 100.Let’s verify by printing the variable i using print(i)

IDLE is good for practicing simple examples.

If you want to write code within IDLE which contains **if** clause or **loops** ,you need to be aware of indentation concepts.

To overcome this, we need an editor which does indentation automatically when we type the code. This is where Jupyter Notebook will be helpful**.**

# Python for data science

### Generating random numbers using the Python standard library

The Python standard library provides a module called **random**, which contains a set of functions for generating random numbers.

The **Python random** module uses a popular and robust pseudo random number generator called the Mersenne Twister.

Let us now look at the process in detail.

Firstly, we need to understand why we need to call the * seed()* function for generating random number.

Let us try to generate random number without calling seed() function. Then we will know the impact of using seed().

The random() function without calling seed(Python for data science) returns a random float in the interval [0.0, 1.0). Each subsequent call to random() will generate a new float value!!

If we call seed() function before calling random(), the chain of calls after random.seed(Python for data science) will produce the same trail of data:

The example below demonstrates seeding the pseudorandom number generator, generates some random numbers, and shows that reseeding the generator will result in the same sequence of numbers being generated.

Running the example seeds the Python for data science generator with the value 4, generates 3 random numbers, reseeds the generator, and shows that the same three random numbers are generated.

Notice the repetition of “random” numbers. The sequence of random numbers becomes deterministic, or completely determined by the seed value, 4

It can be useful to control the random output by setting the seed to some value to ensure that your code produces the same result each time.
