In this assignment you will read through and parse a file with
text and numbers. You will extract all the numbers in the file and
compute the sum of the numbers.
Data Files
We provide two files for this assignment. One is a sample file
where we give you the sum for your testing and the other is the
actual data you need to process for the
assionment
Sample data: http://py4e-data.dr-chuck.net/regex_sum_42.txt L
(There are 90 values with a sum=445833)
Actual data: http://py4e-data.dr-chuck.net/regex_sum_1532106.txt L
(There are 74 values and the sum ends with 805)
These links open in a new window. Make sure to save the file into
the same folder as you will be writing your Python program. Note:
Each student will have a distinct data file
for the assignment - so only use your own data file for
analysis.
Data Format
The file contains much of the text from the introduction of the
textbook except that random numbers are inserted throughout the
text. Here is a sample of the output you
might see:
Why should you learn to write programs? 7746
12 1929 8827
Writing programs (or programming) is a very creative
7 and rewarding activity. You can write programs for
many reasons, ranging from making your living to solving
8837 a difficult data analysis problem to having fun to helping
128
someone else solve a problem.
This book assumes that
everyone needs to know how to program
The sum for the sample text above is 27486. The numbers can appear
anywhere in the line. There can be any number of numbers in each
line (including none).
Handling The Data
The basic outline of this problem is to read the file, look for
integers using the re.findall(), looking for a regular expression
of '[0-9]+' and then converting the extracted
strings to integers and summing up the integers.
