Subset A Dataframe

How to Subset a DataFrame in Python?

In this tutorial, we will go over several ways that you can use to subset a dataframe. If you are importing data into Python then you must be aware of Data Frames. A DataFrame is a two-dimensional data structure, i.e., data is aligned in a tabular fashion in rows and columns. Subsetting a data frame […]

Mean And Sd

Find mean and standard deviation in Python

Mean and standard deviation are two important metrics in Statistics. Mean is sum of all the entries divided by the number of entries. Standard deviation is a measure of the amount of variation or dispersion of a set of values. Let’s look at the steps required in calculating the mean and standard deviation. Steps to […]

Tokenization in python

Tokenization in Python using NLTK

Let’s learn to implement tokenization in Python using the NLTK library. As humans, we heavily depend on language to communicate with one another. Artificial Intelligence also requires computers to understand our language. Making computer understand and process a language comes under Natural Language Processing (NLP). NLP is broadly defined as the automatic manipulation of a […]
