(Python) What is the syntax for this textbook solution? The first and second photos contain the programs code. Step 3 shows what is in 'numbers.txt' and step 4 is the sample output.

Starting out with Python Program: #main function def main(): flag = False #try statement to handle text file exceptions try: #open text file in read mode filel = open('numbers.txt', 'r') #Declare and initialize variables total = 0 count=0 #Use for loop to read all numbers from #text file for line in filel: #try statement to handle value error try: #Make increment in value of count count += 1 #Type cast value into integer type #to perform addition. num = int(line) #Add current read value into total total += num #except statement to handle value error except ValueError: print('Not Integer: String could'+ 'not be converted into integer') flag=True #close text file filel.close() if flag=False: #Calculate and display average on screen Chapter 6 Problem 9PE
