如何为文件中的所有单词添加标签？

Question

我有一个包含单词的文件，我想阅读这个文件并在所有单词前面添加一个标签。标签应该加在单词的右边。例如book - "O"，Berlin - "O"。如何在python中实现它？我试过这个代码，但没有给出答案。你知道吗

inp = open('Dari.pos', 'r')
out = open('DariNER.txt', 'w')

for line in iter(inp):
    word= line.__add__("O")
    out.write(word)
inp.close()
out.close()

Answer 1

如果我理解正确的输出格式word-O，您可以尝试以下操作：

words = open('filename').read().split()
labeled_words = [word+"-O" for word in words]

# And now user your output format, each word a line, separate by tabs, whatever.
# For example new lines
with open('outputfile','w') as output:
    output.write("\n".join(labeled_words))
