Question

CSE 231 Fall 2019 Programming Project 05 This assignment is worth 45 points (4.5% of the course grade) and must be completed and turned in before 11:59 PM on Monday, October 14, 2019. Assignment Overview 1. Functions 2. File input and output 3. try-except Computational facial recognition is growing. Starting with the iPhone X it has even available on smartphones. In this project we examine some of the mathematics behind it. Some of the initial research in facial recognition was by Dr. Anil Jain here at MSU. Use of advanced data structures such as lists, sets, and dictionaries are prohibited. Assignment Background In the field of Computer Graphics, creating and handling shapes is fundamental. Any shape can be represented by what is called a polygon mesh—a collection of vertices, edges and faces that define the shape. A triangle mesh is a common type of polygon mesh where each face is a triangle. The vertices are the points of the shape in 3d space. Each vertex has x,y and z values representing its location in Euclidean space. The vertices are connected by edges that form the triangles. Figure 1 shows an example of triangle mesh representing a dolphin. Figure 1 Triangle mesh (Wikipedia) Figure 2 shows the vertices, edges and faces of a cube represented by a triangle mesh. The vertices are the points of the mesh, the edges are the lines connecting two vertices, and the faces are the triangles that are parts of the surface connecting 3 vertices.
Here I am asked to create a program using functions and files in python 3.7. I am unfortunately not able to use lists in the project. Thanks

Answer 1

1 Python 3.7.4 (d [GCC 6.3.0 2017 def findSumOf Numbers (fileName) main.py 2 sum 0 38 input.txt 4 try: open (fileName) #read lines of file one by one. f = 5 6 for line in f 7 #convert string to integer. CO sum int (line) 9 10 except: print ('Error in finding file', fileName) 11 12 13 return sum 14 15 print(findSum0fNumbers('input.txt) 16

def findSumOfNumbers(fileName):
        sum = 0
        try:
                f = open(fileName)
                # read lines of file one by one.
                for line in f:
                        # convert string to integer.
                        sum += int(line)
        except:
                print('Error in finding file', fileName)

        return sum


print(findSumOfNumbers('input.txt'))

file input.txt:
1
2
5
6
7
8
9

**************************************************
i have created a very simple program which finds the sum of numbers which are in the file.. Each line in file should have a number.
