Q:

How to detect language of a dataframe object?

I want to create a new column in my dataframe review giving the language of the column text which is of type object.
I try to convert to string and then use the detect function from langdetect but, there still a type error when I run the code.
I do not understand the problem lol 
My code : 
from langdetect import detect

review['langue'] = detect((review['text']).astype(str))

Actual result : 
--------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)

TypeError: expected string or bytes-like object

A:

If I correctly understood your question you needs
from langdetect import detect
review['langue'] = review['text'].apply(detect)

detect function expect str as argument, not pd.Series. Instead, you should apply detect function to each element of review['text'] pd.Series.
