Pandas Dataframe：如果A，B或C列中的行包含“x”或＆＃34; y＆＃34;，请将“z”写入新列

Question

与此问题非常相似：Pandas: if row in column A contains "x", write "y" to row in column B

我想知道一行是否包含＆＃34; x＆＃34;或＆＃34; y＆＃34;在多个不同的列中输出＆＃34; z＆＃34;到新专栏。

INPUT：

A        B        C
Cat      Dog     Pig
Monkey   Tiger   Cat
Cow      Sheep   Goat

如果＆＃34; cat＆＃34;或者＆＃34; tiger＆＃34;或者＆＃34;狮子＆＃34; - 输出1到新列

输出

A        B        C       CAT FAMILY
Cat      Dog     Pig          1
Monkey   Tiger   Cat          1
Cow      Sheep   Goat         0

Answer 1

将isin与any和astype

一起使用

In [298]: cat_family = ["Cat", "Tiger", "Lion"]

In [303]: df['CAT_FAMILY'] = df.isin(cat_family).any(1).astype(int)

In [304]: df
Out[304]:
        A      B     C  CAT_FAMILY
0     Cat    Dog   Pig           1
1  Monkey  Tiger   Cat           1
2     Cow  Sheep  Goat           0
