数据框看起来像这样
col_a
Python PY is a general purpose PY language
Programming PY language in Python PY
Its easier to understand PY
The syntax of the language is clean PY
此代码我已尝试实现此功能但无法获得预期的输出。如果有任何帮助表示赞赏。
下面是我用正则表达式处理的代码:
df['col_a'].str.extract(r"([a-zA-Z'-]+\s+PY)\b")
期望的输出:
col_a col_b_PY
Python PY is a general purpose language Python PY purpose PY
