从数据帧中列表内的字典中提取元素

import pandas as pd

# 创建数据帧
data = [{'Name': 'John', 'Age': 25, 'City': 'New York'},
        {'Name': 'Emily', 'Age': 30, 'City': 'Los Angeles'},
        {'Name': 'Michael', 'Age': 35, 'City': 'Chicago'}]

df = pd.DataFrame(data)

# 从数据帧中提取元素
name = df['Name'][0]
age = df['Age'][1]
city = df['City'][2]

print(f"Name: {name}, Age: {age}, City: {city}")

Name: John, Age: 30, City: Chicago
