You like the way the Python `+` operator easily handles adding different numeric types, but you need a tool to do that kind of addition without killing your program with a `TypeError` exception whenever you accidentally try adding incompatible types like strings and lists to numbers.
You decide to write a function `my_add()` that takes two arguments. If the arguments can be added together it returns the sum. If adding the arguments together would raise an error the function should return `None` instead.
For example, `my_add(1, 3.414)` would return `4.414`, but `my_add(42, " is the answer.")` would return `None`.
Hint: using a `try` / `except` statement may simplify this kata.
def my_add(a, b):
    # Your code here.
    try:
      return a + b
    except TypeError:
      print("None")
def my_add(a, b):
    # Your code here.
    try:
      return a + b
    except TypeError:
      print("None")
