Python Script that shows how to use a Hash

Here is a simple example of how to use a hash in Python. This is useful when parsing large amounts of data.

# Define a hash table
hash_table = {}

# Add key-value pairs to the hash table
hash_table["key1"] = "value1"
hash_table["key2"] = "value2"
hash_table["key3"] = "value3"

# Access values in the hash table using keys
print(hash_table["key1"]) # Output: value1
print(hash_table["key2"]) # Output: value2
print(hash_table["key3"]) # Output: value3

# Check if a key is in the hash table
if "key1" in hash_table:
    print("key1 is in the hash table") # Output: key1 is in the hash table

# Delete a key-value pair from the hash table
del hash_table["key1"]

# Check if a key is in the hash table
if "key1" not in hash_table:
    print("key1 is not in the hash table") # Output: key1 is not in the hash table
