Question

Dot Notation can be used with lower(), upper() or str() string methods. true or false

Answer 1

The statement is true; dot notation can indeed be used with the lower(), upper(), or str() string methods to manipulate strings in programming.

Step-by-step explanation:

The statement that Dot Notation can be used with lower(), upper(), or str() string methods is true. Dot notation is a syntactic form that allows access to an object's properties, functions, or methods. In the context of string manipulation in programming languages such as Python, when you have a string object, you can apply various methods to it using dot notation.

For example, the lower() method can be used to convert all characters in a string to lowercase. Similarly, the upper() method converts all characters to uppercase. The str() method is often used to convert a non-string object to a string.

Here's how they can be used in practice:

• my_string.lower() - Turns all characters in my_string to lowercase.
• my_string.upper() - Converts all characters in my_string to uppercase.
• str(my_object) - Converts my_object (which could be any type of object like an integer or a float) to a string format.
