如何将LabelBinarizer列添加到数据帧

here are the first couple of rows of the CSV file that I'm using

import pandas as pd
from sklearn.preprocessing import LabelBinarizer
#import matplotlib.pyplot as plot


#--------------------------------

label_conv = LabelBinarizer()
appstore_original = pd.read_csv("AppleStore.csv")

#--------------------------------

lb_conv = label_conv.fit_transform(appstore["cont_rating"])
column_names = label_conv.classes_

print(column_names)        
print(lb_conv)

我得到了lb_conv和列名。因此:

label_conv 到 appstore_original column_names

如果有人能帮忙,那就太好了。
