Question
Select the correct answerWhich of the following statements is true about Python variables?OptionsPython variables can change data types during execution.Variables in Python are case-insensitive.Python variables must be declared with a data type.Variables in Python can only store numeric values.
Solution
The correct answer is "Python variables can change data types during execution."
This is because Python is a dynamically typed language, which means that the type of a variable is checked during execution (run time), not in advance. Therefore, you can assign a variable to different data types during execution. For example, you can assign a variable to an integer and then to a string.
The other options are incorrect because:
- Variables in Python are case-sensitive, which means Var and var would be two different variables.
- Python variables do not need to be declared with a data type. You can create a variable with the assignment statement, like x = 10.
- Variables in Python can store various types of data, not just numeric values. They can store integers, floating point numbers, strings, lists, dictionaries, etc.
