(iii) if value == 10:
square = value*value

print("The square of ", value,"is",square)
else:
print("Wrong value entered")
Ans. (i) Incorrect case of keywords – if, elif and else
If value == 10: ------ > 'I' of keyword if is in upper case
square = value*value
(ii) The header is not terminated with a colon (:)
if value == 10 --- > colon missing
square = value*value
(iii) Not indenting the statements of if / else / elif blocks correctly
if value == 10:
square = value*value

print("The square of ", value,"is",square) --->Wrong indentation
else:
print("Wrong value entered") --->Wrong indentation

elif(year % 4 == 0):
print('Leap Year')
