小编use*_*275的帖子

嘿，我有一个带有多语言文本的 csv。我想要的只是一个附加了检测到的语言的列。所以我编码如下，

from langdetect import detect 
import csv
with open('C:\\Users\\dell\\Downloads\\stdlang.csv') as csvinput:
with open('C:\\Users\\dell\\Downloads\\stdlang.csv') as csvoutput:
writer = csv.writer(csvoutput, lineterminator='\n')
reader = csv.reader(csvinput)

    all = []
    row = next(reader)
    row.append('Lang')
    all.append(row)

    for row in reader:
        row.append(detect(row[0]))
        all.append(row)

    writer.writerows(all)

但我收到的错误是 LangDetectException: No features in text

回溯如下

runfile('C:/Users/dell/.spyder2-py3/temp.py', wdir='C:/Users/dell/.spyder2-py3')
