创建条件的新df列

Question

我试图在遍历df.series并检查字符串是否包含的同时创建新的df列。

some_list = ['Nashville', 'Oak Ridge']
data.COLUMN
...
'Nashville is a great city'
'Oak Ridge has a research center'

for city in some_list:
    for row in data.COLUMN:
        if city in row:
            data['CITY'] = city

基本上，如果迭代中包含城市，我想从列表中创建一个城市列
