<\/span><\/h2>\nTo print a specific value from a dictionary in Python, you need to use the key associated with that value. Dictionaries use keys as unique identifiers to map values, which makes accessing values by key quite efficient.<\/p>\n
Here is a simple example that demonstrates how to print a specific value from a dictionary:<\/p>\n
“`python
\n# Create a dictionary
\nmy_dict = {“key1”: “value1”, “key2”: “value2”, “key3”: “value3”}<\/p>\n
# Print the value associated with ‘key2’
\nprint(my_dict[“key2”])
\n“`<\/p>\n
The output of this code will be:<\/strong><\/p>\n“`
\nvalue2
\n“`<\/p>\n
In this example, we created a dictionary called `my_dict` with three key-value pairs. To access and print the value associated with the key `’key2’`, we used the square bracket notation `my_dict[“key2”]`. The specified key is enclosed in square brackets, which tells Python to fetch the corresponding value.<\/p>\n
It is important to note that if you try to access a key that does not exist in the dictionary, a `KeyError` will be raised. To handle this situation, you can use the `get()` method, which allows you to provide a default value if the key is not found:<\/p>\n
“`python
\n# Print the value associated with ‘key4’ or a default value of ‘Not Found’
\nprint(my_dict.get(“key4”, “Not Found”))
\n“`<\/p>\n
The output of this code will be:<\/strong><\/p>\n“`
\nNot Found
\n“`<\/p>\n
Using the `get()` method, you can avoid raising a `KeyError` when accessing a non-existent key by providing a default value as the second argument.<\/p>\n
