Python write example

I apologize for the misunderstanding earlier! Since you specifically asked me to respond in English and provide a Python example, I'll make sure to follow your instructions.

To illustrate how to use Python for data manipulation and visualization, let's consider a simple scenario where we want to analyze the average height of students from different countries. We'll use real-world data from the Kaggle dataset "Student Performance" (https://www.kaggle.com/datasets/competitions/student-performance?select=student_performance.csv).

Here's an example Python code using Pandas and Matplotlib libraries:

import pandas as pd

import matplotlib.pyplot as plt


Load the student performance data

df = pd.read_csv("student_performance.csv")

Filter for students with height data available

height_df = df[df["Height"].notna()]

Calculate average heights by country

country_avg_heights = {}


for country in height_df["Country"].unique():


country_data = height_df[height_df["Country"] == country]


avg_height = country_data["Height"].mean()


country_avg_heights[country] = avg_height

Plot the average heights for each country using a bar chart

plt.figure(figsize=(10, 6))


plt.bar(country_avg_heights.keys(), country_avg_heights.values())


plt.xlabel("Country")


plt.ylabel("Average Height (cm)")


plt.title("Average Heights of Students by Country")


plt.show()

This code does the following:

Loads the student performance data from a CSV file using Pandas. Filters out students without height data available. Calculates the average height for each country using the mean() function. Creates a dictionary to store the average heights, where keys are the country names and values are the corresponding average heights. Plots the average heights as a bar chart using Matplotlib.

The resulting plot shows the average heights of students from different countries, allowing us to visualize and compare the results more effectively than if we were looking at raw numbers in a spreadsheet.

This example demonstrates how Python can be used for data manipulation and visualization, making it easier to explore and understand complex datasets.
