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."
