map Include in Python 3.10

In Python 3.10, checking if a hash includes a key can be done using the in operator.

Here is an example:

# Define a hash
my_dict = {"apple": 2, "banana": 4, "orange": 1}
# Check if a key exists in the hash

if "apple" in my_dict:

    print("Yes, 'apple' is a key in the hash.")

else:

    print("No, 'apple' is not a key in the hash.")

In this example, "apple" is a key in the hash, so the output will be "Yes, 'apple' is a key in the hash."

Here's another example:

# Define a hash
my_dict = {"cat": "meow", "dog": "woof", "bird": "chirp"}
# Check if a key exists in the hash

if "monkey" in my_dict:

    print("Yes, 'monkey' is a key in the hash.")

else:

    print("No, 'monkey' is not a key in the hash.")

In this example, "monkey" is not a key in the hash, so the output will be "No, 'monkey' is not a key in the hash."
