Hello I need help fixing lines 16 and line 41. I'm not sure how to fix an UnsupportedOperation error.Here are the instructions:You must have a function that accepts three test scores and returns the float averageYou will calculate the average for an unknown number of students, by reading the data from a file named scores.txt.You must print the students’ average scores to the screen as shown aboveYou must write the specified output to a file named grades.txtYou may not use any global variables The input will come from a text file named scores.txt, which consists of multiple sets of a student IDnumber followed by three test scores. The contents of a file containing the scores of four students areshown below (the student ID number is of the form MXX where XX is a two-digit number):M01768982M02918183M039293M02 85.00M03 91.67M04 88.3390M04868891The output of the above data to the screen will be of the following form (note: 2 decimal places):Student M01 average is 82.33Student M02 average is 85.00Student M03 average is 91.67Student M04 average is 88.33Only the student ID number and average score (separated by a space and formatted to 2 decimal places)are written to the output file:M01 82.33 6 def calc_average (scorel, score2, score3):7n = 089101112B 14 15 16 17 18 19 28 21 22 23 24 25 26 27 28 298128343567839 48 1 2 3 4 45 451320304041424344def46read_fileout_file =for i in range (n):out_file.write(str(n))out_file.write("\n")out_file.close()inFile =open("grades.txt", "w")line = inFile.readlines ()count = 0str(input("Enter the name of the file to which the final results can be read:"))open("scores.txt","r")avg_total = 0=for i in range(n):score2student = input("Name: ")count + 1score1= 0= 0score3 = 0int(line)avg_totalprint (name, avg_total)inFile.close()main ():file_name45 main()student =return avg_totali = 0==student_count = 0str(input ("Enter the name of the file to which results should've been written: "))while student_count !=score1 = 0score2 = 01score3 = 0student_count +=1avg_total calc_average (scorel, score2, score3)print('Student', student, 'average', avg_total)=

Code is attached below and screenshot. Please make sure you output a file name grade.txt (In my sample run I have written a output.txt) make sure both txt file and .py file is in same folder. assuming record will be in multiple of 4 (no error checking is done because it is not asked).---- Working code------ def calc_average(m1,m2,m3): return (m1+m2+m3)/3 def main(): fname=input("Enter a file name for reading a data: ") f = open(fname, "r") fn2=input("Enter a file name for writting a data: ") f1=open(fn2,"w") data1=f.read().split("\n") length=len(data1) if(len(data1)%4!=0): length=len(data1)-1 for i in range(0,length,4): num=data1[i] s1=int(data1[i+1]) s2=int(data1[i+2]) s3=int(data1[i+3]) avg=calc_average(s1,s2,s3) print("Student {} average is {:0.2f}".format(num,avg)) string= num+" "+"{:.2f}".format(avg) f1.write(string+"\n") main()
