编写表达式以使用pandas从列中拾取特定内容

# 导入pandas库
import pandas as pd

# 创建一个示例DataFrame
df = pd.DataFrame({'column1': ['apple', 'banana', 'orange'],
                   'column2': ['I like apple', 'I prefer banana', 'I love orange']})

# 使用str.extract()方法和正则表达式提取特定内容
df['extracted_content'] = df['column2'].str.extract('(apple|banana|orange)')

# 打印DataFrame
print(df)

  column1        column2 extracted_content
0   apple   I like apple             apple
1  banana  I prefer banana            banana
2  orange  I love orange            orange
