The maintainablity index is always in the range 0-100 and is ranked as follow:
- A MI in the range 0-9 maps to a code extremely difficult to maintain.
- A MI in the range 10-19 maps to a maintainable code.
- A MI in the range 20-100 maps to a code highly maintainable.

Example
'''
The maintainability index for the following piece of code is 100.
'''
def preorder(node):
if tree:
print(node.key)
preorder(node.left)
preorder(node.right)Importance
Complex codes are difficult to maintain.
How to fix this
This can be solved by writing simpler functions and methods.
