Pandas is an open-source Python library used for data analysis and manipulation. Pandas provides functionality for data cleaning, transformation, and filtering. In large datasets, some extreme values called outliers can modify the data analysis result. In order to identify those outliers, a robust statistical measure called the Interquartile range (IQR) is used. In this article, we will understand how pandas filter with the IQR to identify and handle outliers in the dataset. Understanding the Interquartile Range (IQR) Before understanding how to use the Pandas filter with IQR, let’s briefly understand what is Interquartile range(IQR). Quartile divides a dataset into four ... Read More

Pandas is a Python library that is used for data manipulation and analysis of structured data. The cut() and qcut() methods of pandas are used for creating categorical variables from numerical data. The cut() and qcut() methods split the numerical data into discrete intervals or quantiles respectively and assign labels to each interval or quantile. In this article, we will understand the functionalities of the cut() and qcut() methods with the help of various examples. The cut() Function The cut() divides a continuous variable into discrete bins or intervals based on specified criteria. It creates groups or categories of ... Read More

The apply() function in pandas is used to apply a custom function to the data frame or series. The apply() function can be used to perform transformations, computation, and other operations on the data. The apply() function returns a new Data frame or series by default. We can also modify the dataframe or series by using the inplace parameter of the apply() function. In this article, we will understand how we can use apply() function inplace with the help of examples. Syntax of apply() Function df.apply(func, axis=0) Here, df is the dataframe on which we need to apply ... Read More

The Numpy where() function allows us to perform element-wise conditional operations on array. Numpy is a Python library that is used for numerical computation and data manipulation. To use where() method with multiple conditions in Python we can use logical operators like & (and), | (or) and ~ (not). In this article, we will explore some examples to use numpy where() with multiple method in Python. Syntax of where() Method numpy.where(condition, x, y) Here, the `condition` parameter is a boolean array or a condition that evaluates to a boolean array. The x and y are arrays which ... Read More

Scaling is the process of preprocessing the data in data analysis and ensuring that all the features in a dataset have similar ranges, making them more comparable and reducing the impact of different scales on machine learning algorithms. We can scale Pandas dataframe columns using methods like Min-max scaling, standardization, Robust scaling, and log transformation. In this article we will dive into the process of scaling pandas dataframe scaling using various methods. Why Scaling is Important? Some features in the data may have larger values which can dominate when the analysis or model training is done. Scaling ensures ... Read More

In this article we will get to know about various method using which we can find the prefix tuple records using python programming language. Tuple is an immutable sequence-like list whose value cannot be changed once assigned. Here prefix tuple is a collection of tuples which have a common prefix. Each element of tuple can be of any data type or it can also be in mixed form. Example records = [('Kalyan', 123), ('Gungun', 122), ('Komal', 456), ('Isestru', 789), ('Kosal', 321)] prefix = 'Ko' Here you can see we have list of records where tuples are there in ... Read More
