基于行比较删除python pandas DataFrame中的特定行

import pandas as pd

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

condition = df['Age'] > 30

df = df[~condition]

print(df)

import pandas as pd

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

condition = df['Age'] > 30
df = df[~condition]

print(df)

   Name  Age      City
