# Derivatives

What is the derivative of a function? The derivative is a measure of how the function behaves with little changes in the parameters of the function. Let’s dumb it down further.

## Probability

Probability is defined as the ratio of the number of desired outcomes and the number of total outcomes. If you…

# Numpy

Numpy is a python library popular in the data science community. It can be used for multidimensional large array manipulation. It is also used for mathematical operations on arrays.

`import numpy as np`

## Numpy array creation

Numpy arrays are homogeneous data structures, the data in an array has to be of the same data type.

`>>> a_list = [1,2,3,4,5,6,7,8,9]>>> a_arr=np.array(a_list) …`

# List

## List indexing

Python list indexing is Zero-based indexing. In which 1st element is indexed as 0, the second element is indexed as 1 as so on…

`>>> a_list=['first','second','third','fourth']>>> print(a_list[0])first>>> print(a_list[1])second`
`>>> print(a_list[-1])fourth>>> print(a_list[-2])…`
