如何使用pandas从字典中删除行

import pandas as pd

data = {'Name': ['John', 'Emma', 'Mike', 'Sophia'],
        'Age': [25, 28, 30, 22],
        'City': ['New York', 'London', 'Paris', 'Tokyo']}

df = pd.DataFrame(data)

df = df[df['Age'] != 30]

print(df)

import pandas as pd

data = {'Name': ['John', 'Emma', 'Mike', 'Sophia'],
        'Age': [25, 28, 30, 22],
        'City': ['New York', 'London', 'Paris', 'Tokyo']}

df = pd.DataFrame(data)
df = df[df['Age'] != 30]
print(df)
