ruby hash delete

To delete a key-value pair from a Ruby hash, you can use the delete method. Here are the steps involved:

  1. Identify the hash: First, you need to identify the hash from which you want to delete the key-value pair.

  2. Specify the key: Next, specify the key of the key-value pair that you want to delete from the hash.

  3. Call the delete method: Finally, call the delete method on the hash, passing in the key as an argument. This will remove the specified key-value pair from the hash.

Here is an example code snippet that demonstrates the above steps:

# Step 1: Identify the hash
my_hash = { "key1" => "value1", "key2" => "value2", "key3" => "value3" }

# Step 2: Specify the key
key_to_delete = "key2"

# Step 3: Call the delete method
my_hash.delete(key_to_delete)

After executing the above code, the key-value pair with the key "key2" will be deleted from the my_hash hash.
