向具有预加载数据的pandas DataFrame添加一行

import pandas as pd

# 创建一个预加载数据的DataFrame
data = {'Name': ['John', 'Emma', 'Mike'],
        'Age': [25, 28, 30],
        'City': ['New York', 'London', 'Paris']}
df = pd.DataFrame(data)

# 创建新的行数据
new_row = pd.Series(['Tom', 32, 'Sydney'], index=df.columns)

# 添加新的行数据到DataFrame
df = df.append(new_row, ignore_index=True)

print(df)
