3. writ a program, student Avg(ifile), which will calculate the average score for each e student. Each file contains a name followed by an id followed by a series of eight grades. This program will calculate the average score for each student. Include in the code, except code to catch non-numeric grades. Non will be by-passed in the average calculation. The code will also use try/except to catch the file not found error. In addition, the code will use a try/except to check for an empty file. The code for this check is in the template. Place it in the appropriate try/except position. studentAvg empty file.txt') File is empty studentAvg ('nosuchfile. txt') File not found p>> student Avg grade s2.txt Error Non-numeric Name Domel Number of assignments 7 Average score 0.0', Name Fischer Number of assignments: 8 Average score: 90.0 studentavg ('grade sl txt') ['Error Non-numeric Name: Domel Number of assignments 7 Average score 81.428 57142 857143 Name Fischer Number of assignments: 8 Average score 74.125 'N ame: Hope Number of assignments 8 Average score 100.0 Name Patel Number of assignments 8 Average score 90.375']

Explanation / Answer

def studentAvg(fname):
try:
f = open(fname, 'r')
tmp_vals = []
correct_rcrs = []
for val in f:
tmp_vals.append(val.strip(' '))
if len(tmp_vals) == 0:
print("File is Empty")
else:
for val in tmp_vals:
tmp_val = val.split(' ')
correct_rcrs.append(tmp_val)

for i in range(len(correct_rcrs)):
temp_val = correct_rcrs[i][2:]

temp_val = list(filter(None, temp_val))

sum_of_vals = 0
no_of_records =0
for k in temp_val:

if k.isdigit():
no_of_records += 1

sum_of_vals += int(k)
else:
pass

print("Name: ", correct_rcrs[i][0], "No.of records: ", str(no_of_records), "Average: ", str(sum_of_vals/no_of_records))
  
  
  
except:
print("File Not Found")
