Question

Sum Second Write a shell (text-based) program, called sum_second.py, that opens a text file called stuff.txt with 2 numbers per line separated by commas and prints out the sum of the second numbers on every line.

For example, if stuff.txt has the following lines:

500,55

300,45

200,7

400,20

Then the following example output would happen.

PS C:\Users\ssiva\Desktop> python sum_second.py Sum: 127 PS C:\Users\ssiva\Desktop>

Answer 1

Programming code:

inFile = open("stuff.txt", "r")

num = []

Sum = 0

for val in inFile.readlines():
value = val.split(",")
Sum = Sum + int(value[1])

print("Sum of second number on every line in the file is: ", Sum)

inFile.close()

Output:

Python 3.6.1 (default, Dec 2015, 13:05:11) [GCC 4.8.2] on linux Sum of second number on every line in the file is: 127
