How to print one value from a dictionary in Python?

Answer:

**To print one value from a dictionary in Python, you can simply access the value by using the key associated with it.**

For example, if you have a dictionary called `my_dict` with the key `’name’`, you can print the value associated with that key by using `print(my_dict[‘name’])`.

Here is an example:
“`
my_dict = {‘name’: ‘John’, ‘age’: 30}
print(my_dict[‘name’]) # Output: John
“`
