Question

Write a program to print out the line number, the number of values in each line and total value of each line of the file.

file name is File_Lab1.txt.

output example:

Line 1 has 3 values and total is 60

Line 2 has 1 values and total is 20

Line 3 has 2 values and the total is 5096

Answer 1

Breaking the problem down into basic steps:

1. Read each line from the file
2. Start off the line counter at 1
3. Read each number on the line to an array
4. Convert the strings to integers
5. Get the total sum of the line
6. Get the numbers on the line
7. Print out the data in the expected format
8. Increment the line counter
9. Restart from step 3 if there are additional lines in the file

Using Python3:

# Open the file and read the lines into a list called lines

with open("File_Lab1.txt", "r") as file:

lines = file.readlines()

current_line = 1

for line in lines:

# Remove whitespace at the end of the line

line.strip()

# if the numbers are separated by a space them split them up and store them in the values list

values = line.split(" ")

# By default the list are strings so convert each item to an integer so we can add them together

values = [int(x) for x in values]

# Sum up all of the values on the line

total = sum(values)

# The number of values on the line is equal to the number of items in the list

number_of_values = len(values)

print(f"Line {current_line} has {number_of_values} values and the total is {total}")

# Increment current_line

current_line += 1
