Pandas get row by index

This can be useful for various reasons such as identifying specific rows, filtering data, or performing calculations on specific rows.

As a data scientist or software engineer, you may often work with large datasets in your projects. One of the most popular tools for data manipulation and analysis is the Pandas library in Python. Pandas provides an easy-to-use interface for handling tabular data, but sometimes you may need to retrieve the index of a specific row in a DataFrame as an integer. In this article, we will explore different methods to obtain the index of a row in a Pandas DataFrame as an integer. A Pandas DataFrame is a two-dimensional labeled data structure with columns of potentially different types. It is similar to a spreadsheet or SQL table, where each row represents an observation and each column represents a variable.

Pandas get row by index

You can select and get rows, columns, and elements in pandas. DataFrame and pandas. Series by index numbers and names using [] square brackets. You can use at , iat , loc , and iloc to select a range more explicitly. The sample code in this article is based on pandas version 2. The following DataFrame is used as an example. You may also specify a column name like. Note that if the column name conflicts with existing method names, the method takes precedence. You can get multiple columns as DataFrame by specifying a list of column names in []. The columns will be in the order of the specified list. If you specify a list with one element, a single-column DataFrame is returned, not a Series. You can also use loc to specify a slice based on column names, and iloc to select columns by their numbers, either individually or as a range list or slice. You may specify a negative value and step start:stop:step as in a normal slice. For example, you can use slices to extract odd or even rows.

The pandas library in Python comes with a number of useful methods to help you work with and manipulate tabular data. In this tutorial, we will look at how to get the rows of a pandas dataframe by their respective index with the help of some examples. You can access one or more rows of a pandas dataframe by its index using the iloc property of the dataframe. You can use the pandas dataframe loc property to access one or more rows of a dataframe by their row labels. Disclaimer: Data Science Parichay is reader supported.
