在熊猫系列中找到一个单词的完全匹配

Question

我下面有一个数据框

news                 score
testing tools           12
test match              32
he is testing           332
test is done             23

我想要这样的结果

news                        score
test match                   32
test is done                 23

ddf[ddf['news'].str.contains('test', regex= False)]

ddf[ddf['news'].str.contains('test', regex= False)]

Answer 1

尝试一下：

pattern = '/\btest\b/'
ddf[ddf['news'].str.contains(pattern, regex= True)]
