""" Easier to ask forgiveness than permission """

my_dict = {"key_0": 0,
           "key_1": 10,
           "key_2": 20,
           "key_3": 30,
           "key_4": 40,
          }


# Verbose way
def my_dict_return(key_string):
    try:
        return my_dict[key_string]
    except KeyError:
        print("No matching key")
        return None

my_dict_return("key_1")
>>> 10
my_dict_return("key_99")
>>> No matching key


# Pythonic way
my_dict.get("key_3", None)
>>> 30
my_dict.get("key_98", None)
>>> 

# Awesome!! :)
