Compare Two CSV Files Using Python

Python offers a simple and effective way to compare two CSV files using libraries such as pandas and csv. You can use pandas to read both CSV files into data frames and then use built-in functions like equals() or merge() to find differences between them. Alternatively, the csv module provides a more lightweight approach by reading files line-by-line and comparing them manually.

Here is a basic example using pandas:

import pandas as pd

# Load CSV files into DataFrames
df1 = pd.read_csv('file1.csv')
df2 = pd.read_csv('file2.csv')

# Compare DataFrames and identify differences
differences = df1.compare(df2)

# Output the differences
print(differences)

This script reads two CSV files, compares their contents, and prints any discrepancies found, providing a quick way to ensure data consistency and accuracy.
