code (try-except)

The python function, find_average() given below, is written to accept a list of marks and return the average marks. On execution, the program is resulting in an error.

1: Add code to handle the exception occurring in the code.

2: Make the necessary correction in the program to remove the error.

3: Make the following changes in the code, execute, observe the results. Add code to handle the errors occurring in each case.

Case – 1: Initialize m_list as ["1",2,3,4]

Case – 2: Initialize m_list as given below

mark1="A"

mark1=int("A")

m_list=[mark1,2,3,4]

Case – 3: Initialize m_list as []

Case – 4: Make the following change in the for loop statement

for i in range(0, len(mark_list)+1):

SOLUTION:

	def find_average(mark_list):
	total=0
	try:
	for i in range(0, len(mark_list)):
	total+=mark_list[i]
	marks_avg=total/(len(mark_list))
	return marks_avg
	except NameError:
	print("name error")
	except ZeroDivisionError:
	print("Divide by zero error")
	except TypeError:
	print("Wrong data type")
	except IndexError:
	print("list index out of range")
	except:
	print("Some other error")
	try:
	m_list=[1,2,3,4]
	print("Average marks:", find_average(m_list))
	except:
	print("Some other error")
