Question

(IN PYTHON) Download file homeruns.txt from Canvas. Your program must ask the user for the file name the read that file. Your program must catch an exception if the file isn’t found. It is a comma-delimited file with 2 fields on each line, a year and a number of home runs. Your program should have functions to determine the year with the most home runs, the year with the fewest number of home runs, and the average home runs for all years. You can have more functions if you desire. You should print the following information: the year with the most home runs and how many that is, the year with the fewest number of home runs and how many that is, and the average number of home runs per year.

the following is what was in the file homeruns.txt

CODE

#function to find most homeruns and year
def max_home_runs(year, homerun):
   #initializing max, max_year, i
   max = homerun[0]
   max_year = year[0]
   i = 0
  
   #loop to find most homerun
   for run in homerun:
       #finding most homerun and year
       if run > max:
           max = run
           max_year = year[i]
       i = i + 1
   #returns most homerun and year
   return max, max_year

#function to find fewest homeruns and year
def min_home_runs(year, homerun):
   #initializing min, min_year, i
   min = homerun[0]
   min_year = year[0]
   i = 0
  
   #loop to find fewest homerun
   for run in homerun:
       #finding fewest homerun and year
       if run < min:
           min = run
           min_year = year[i]
       i = i + 1
   #returns fewest homerun and year
   return min, min_year

#function to find average homerun
def average(homerun):
   #initializing total
   total = 0
  
   #loop to find total homerun
   for i in homerun:
       #calculating total homerun
       total = total + i
   #calculating average homerun
   avg = total / len(homerun)
  
   #returns average homerun
   return avg

#prompt for filename
filename = input("Enter your file name: ")

#Trying to open file
try:
   file = open(filename, "r")
#catching exception if file not found
except:
   print("File Not Found!")

#list to store year and homerun
year = []
homerun = []
  
#reading each line
for line in file:
   #removing "\n" from each line
   line = line.strip()
  
   #spliting each line
   data = line.split(",")
  
   #appending year to list
   year.append(data[0])
  
   #appending homerun to list
   homerun.append(int(data[1]))

#calling max_home_runs
max, max_year = max_home_runs(year, homerun)

#printing most homerun and year
print("Most home runs\t:", max, "Year:", max_year)

#calling min_home_runs
min, min_year = min_home_runs(year, homerun)

#printing fewest homerun and year
print("Fewest home runs:", min, "Year:", min_year)

#calling average
avg = average(homerun)

#printing average
print("Average:", "{0:.2f}".format(avg))
