Python is a popular programming language in the field of data science due to its simplicity, versatility, and powerful libraries. It provides numerous tools and packages that make data manipulation and analysis efficient and straightforward.

Python has a simple and easily-readable syntax that allows beginners to grasp the basics quickly. Let's look at an example of how Python can be used for data manipulation:

# Importing pandas library
import pandas as pd

# Reading a CSV file
data = pd.read_csv('data.csv')

# Excluding invalid rows
data = data.dropna()

# Computing the mean of a column
mean_value = data['column_name'].mean()

# Printing the result
print(mean_value)
