The problem I met unsolved

In the process of working, I have met many questions, some had been solved that i may forget the method to solving the problem. Some have not been solved, so it’s necessary to write these problem and conquer when inspiration comes to me.

1. When I used the package of Flask to buid my api, i sent a format of string to the api, but when the symbol '# ’ in the string, the front of the '# ’ is lefted and the behind of the ‘#’ is cut nowhere, the program is as follows:

def opinionAnalysis():
    sentence = None
    if request.method == "POST":
        sentence = request.form.get("title")
    else:
        sentence = request.args.get("title")
    oa = OpinionAnalysis(data_dir, model_dir)
    return oa.unit_sample_test(sentence)

I have used resuest.form.get 、 request.args.getand request.values.get, but it made no use.
