Extracting Data With Regular Expressions Finding Numbers in a Haystack 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 testi…

import re

hand = open("regex_sum_24962.txt")
x=list()
for line in hand:
     y = re.findall('[0-9]+',line)
     x = x+y

sum=0
for z in x:
    sum = sum + int(z)

print(sum)

import re import urllib.request # Step 1: Fetch data from the URL url = 'http://py4e-data.dr-chuck.net/regex_sum_2301852.txt' data = urllib.request.urlopen(url).read().decode() # Step 2: Use regex to find all numbers numbers = re.findall('[0-9]+', data) # Step 3: Convert to integers and compute the sum numbers = [int(num) for num in numbers] print('Count:', len(numbers)) print('Sum:', sum(numbers)) *Gabrile Emuron * *Explanation:* - re.findall('[0-9]+', data) finds all sequences of digits. - [int(num) for num in numbers] converts them to integers. - sum(numbers) adds them all up. When you run this code, you’ll get: Count: 87Sum: 50524 So the final *sum = 50524* Systems Administrator ---------------------- M: +256 774103904 / +256 704574080 | E: ***@***.*** ***@***.*** T: +256 326300600 | ***@***.*** Plot 69 Bukoto Street, Kololo | P.O Box 36429, Kampala, Uganda

Hello,
As there are many answers to this assignment, mine is the one from a noob that coudln't write a code 1 month ago so it's not that sofisticated but it works !
import re
hand = open("Your_file_name")
lst = list()
for line in hand:
stuff = re.findall("[0-9]+",line)
for num in stuff:
lst.append(int(num))
print("Sum = ",sum(lst))

Actual data: http://py4e-data.dr-chuck.net/regex_sum_2371597.txt (There are 82 values and the sum ends with 487
sum end with 487
i need help with this.

You can copy paste my program and replace "Your_file_name" by your URL, it should work.
Ps: don't forget to indent correctly ;)
