Introduction to NumPy

<aside> <img src="/icons/snowflake_purple.svg" alt="/icons/snowflake_purple.svg" width="40px" /> Numpy is a library or Python package. It stands for ‘Numeric Python.’. It is a library that consist of multidimensional array object and a group of operation to process array.

Operation that is in NumPy In NumPy, programmer can use these operations:

• Math and Logic operation.
• Operation that close with linear algebra and have the built-in function to do linear algebra operation and generate number randomly.
• NumPy also have function to do advance operation such Fourier transform and many more. </aside>

NumPy and Machine Learning?

Relation NumPy is open-source library that provides math computation function that is very fast for array and matrix.

NumPy and Array Object

The most important object that is defined by NumPy is N-dimension array type that is called by**ndrarray.**

It pictures collection of items from the same types. Item in the collection can be accessed using basis 0 index.

Every item in ndrarray take the same block size in the memory. Each of element in the ndrarray is object from data type object (called by dtype).

Data Type on NumPy Array

NumPy has some additional data type and refers to the data type with 1 character such as i for Integer, U for unicode string and many more.
