Question

• For each problem, you must:
  
  1. Write a Python program
  2. Test, debug, and execute the Python program
  3. Save your program in a .py file and submit your commented code to your Student Page.
  4. Note regarding comments: For every class, method or function you create, you must provide a brief description of the what the code does as well as the specific details of the interface (input and output) of the function or method.

1. (25 pts.) Write a program that reads in a file that contains lines consisting of a student name and five numbers representing the scores marks in English, History, Math, Biology, and Spanish. For example, the file might consist of the following lines:

   Baker 91 87 71 62 79
   Jones 55 88 77 99 56
   Smith 62 56 82 77 92

   Use five dictionaries (one for each subject) to store the names and numbers. Once all the names and numbers have been stored, add a function that utilizes the newly created dictionaries to print out the names of all students with failing grades (less than 60) along with the subjects they failed. Note: The data file that will be used to test the programs will only contain last names and all data items will be separated by a space.

Answer 1

//code screenshot

//code

#this function takes all the dictionaries and prints the failures
def printFailures(english,history,math,biology,spanish):
#loops through the five dictionaries and prints the student who has marks less than 60
for d in english:
if(english[d]<60):
print(d,' ',english[d],' English')
for d in history:
if(history[d]<60):
print(d,' ',history[d],' History')
for d in math:
if(math[d]<60):
print(d,' ',math[d],' Math')
for d in biology:
if(biology[d]<60):
print(d,' ',biology[d],' Biology')
for d in spanish:
if(spanish[d]<60):
print(d,' ',spanish[d],' Spanish')

#declared five dictionaries.
english={}
history={}
math={}
biology={}
spanish={}
#opens the file and generates the dictionaries
with open("marks.txt","r") as file:
lines=file.readlines() #reads all the lines from the file
for line in lines: #taking each line from lines
arr = line.split(' ') #splits the lien and populates the dictionaries
english[arr[0]]=int(arr[1])
history[arr[0]]=int(arr[2])
math[arr[0]]=int(arr[3])
biology[arr[0]]=int(arr[4])
spanish[arr[0]]=int(arr[5])

#calls the printFailures function
printFailures(english,history,math,biology,spanish)
