Method Overloading.py

# Method Overloading: Same method name but the difference is in the size of parameters or data type of parameters or both. 
# We can't directly use method overloading in python. To use it we have to install "multipledispatch" package.
# To use multipledispatch, you need to install the package first. You can do this using a package manager like pip:  pip install multipledispatch
# Features of method overloading: Flexibility, Readability, Program Complexity decrease.
