Pandas sum

As a data pandas sum or software engineer, you may often need to perform calculations on data stored in a Pandas DataFrame. One common task is to sum two columns in a DataFrame.

Pandas is a popular open-source library for data manipulation and analysis in Python. It provides high-performance, easy-to-use data structures, and data analysis tools. Pandas dataframes are a two-dimensional, size-mutable, tabular data structure with columns of potentially different types. Suppose you have a pandas dataframe with a large number of rows and columns, and you need to calculate the sum of values in a row. You might be tempted to use a for loop to iterate through each row and sum the values. However, this can be slow and inefficient, especially for large datasets. The most efficient way to sum values of a row of a pandas dataframe is to use the sum method with the axis parameter set to 1.
