如何在python中使用(行、列)指定的值迭代数据框以进行绘图

pip install pandas

import pandas as pd
import matplotlib.pyplot as plt

data = {'Name': ['Alice', 'Bob', 'Charlie', 'David'],
        'Age': [25, 30, 35, 40],
        'Salary': [50000, 60000, 70000, 80000]}
df = pd.DataFrame(data)

for index, row in df.iterrows():
    print(row['Name'], row['Age'])

plt.bar(df['Name'], df['Salary'])
plt.xlabel('Name')
plt.ylabel('Salary')
plt.title('Salary by Name')
plt.show()
