How can a name be extracted from a variable in a dynamic manner?

edit

If the variable contains a string that represents a name, you can simply access the value of the variable using the variable name.

For example, if the variable is called name, and it contains the string value "John", you can extract the name by using the variable name:

name = "John"
extracted_name = name

However, if the variable contains a more complex data structure (like a dictionary or list), you'll need to access the specific element that contains the name. This can usually be done by using the correct index or key.

For example, if the variable is a dictionary and the name is associated with a specific key (like "first_name"), you can extract the name by using the key to access the associated value:

person = {"first_name": "John", "last_name": "Doe"}
extracted_name = person["first_name"]

Alternatively, if the variable is an array and the name is associated with a specific index position (like the first element), you can extract the name by using the correct index:

names = ["John", "Jane", "Bob"]
extracted_name = names[0]
