how to label sentiment polarity in big text file?

Question

Need some help with it! Sorry if it's sound stupid. I am new to python and want to try this example....

but labeling was made manually which is hard work if I have two .txt files(pos and neg) each with 1000 tweets.

Using example above how can I use it with text files?

Answer 1

If I understood correctly, you need to figure out a way of reading text file into a Python object.

Considering you have two text files that contain positive and negative samples (pos.txt and neg.txt) with one tweet per line:

train_samples = {}

with file('pos.txt', 'rt') as f:
    for line in f.readlines():
        train_samples[line] = 'pos'

Repeat the above loop for negative tweets and you are done populating your train_samples.
