Just a quick response, but your data is more than a text file its a CSV
file so the rules change slightly. Especially since you are using the csv
module.
Your data file is not a CSV file - it is just space separated and the
string is not quoted so the CSV default mode of operation won;t
work on this data as you seem to expect it to,. You will need to
specify the separator (as what? A space wiill split on each word...)
CSV might not be the best option here a simple string split combined
with slicing might be better.

The CSV module prefers binary files so open it with mode 'rb' not 'r'

Try printing the first 2 lines of reviews to check what you have.
I suspect it's not what you think.

str(1) is just '1' so you might as well just use that.

See the comments above about your data format.
