Write a list into Excel

问题

I have a sentence 'And now for something completely different'. I want to tokenize it, tag it and store it into a excel file for further processing.
<pre>sent = "And now for something completely different" words = nltk.word_tokenize(sent) tags = nltk.pos_tag() print tags</pre>

The result of above is the words with their tag in a nested list format.

[('And', 'CC'), ('now', 'RB'), ('for', 'IN'), ('something', 'NN'), ('completely', 'RB'), ('different', 'JJ')]

I want to store this result list into a excel file, with words in one column and tags to the other.

I tried the following code to achieve the above.

fd = open("output.txt",'w')
i=0
for words in tags:
    for word in words:
        i+=1
        fd.write(word)
        if i==1:
            fd.write('\t')
        fd.write('\n')
    i=0

The above code will perfectly write the words and tag into the output file. If I use shutil method to copy from the text file to excel format, it will execute perfectly. The problem comes when I try to read the converted. I get the following error.

XLRDError: Unsupported format, or currupt file: Expected BOF record; founf 'And\tCC\n'

Can anyone tell me how do I write the tagged list to the output file such that I the above error can be resolved?

回答1:

Excel files (xlsx) are not just simple flat files, so trying to copy a text file to xlsx will not work. You could save the file as csv and open it in Excel. I think pandas is really useful for parsing and writing data files (obviously it is also useful for processing data).

import pandas as pd
df = pd.DataFrame(tags)
df.to_excel('output.xlsx', header=False, index=False)

Instead writing to excel format. You already writing your file into a tab-separated-value. Excel knows how to read that. I suggest you save your file with '.tsv' extension and open it in excel.
