import pandas as pd

# 创建示例数据帧
data = {'Name': ['John', 'Doe', 'Alice', 'Bob'],
        'Age': [30, 25, 35, 40],
        'City': ['New York', 'London', 'Paris', 'Tokyo']}
df = pd.DataFrame(data)

# 删除索引为0的行
df.drop(0, inplace=True)

print(df)

   Name  Age     City
1   Doe   25   London
2  Alice   35    Paris
3    Bob   40    Tokyo

        'Age': [30, 25, 35, 40],
        'City': ['New York', 'London', 'Paris', 'Tokyo']}
df = pd.DataFrame(data)

# 删除Age列大于30的行
df.drop(df[df['Age'] > 30].index, inplace=True)

print(df)
