python等同于带有条件的“ grepl” R

Question

以下是R代码。 我可以知道与下面的代码等效的python吗？ 特别是

grepl("dog|cat", data$animal)

部分代码

data <- data.frame(animal = sample(c("cat","dog","bird",'doggy','kittycat'), 
                                       10, replace = T)) 
ifelse(grepl("dog|cat", data$animal), "keep", "discard")

Answer 1

将re用于正则表达式，遍历动物，并通过与None比较来测试是否存在匹配项：

>>> animal = ["cat","dog","doggy","kittycat","bird","dog"]
>>> import re
>>> [re.search("cat|dog",a) is not None for a in animal]
[True, True, True, True, False, True]
