Chapter 11: Problem 1

Name three ways that you can assign three variables to the same value.

Short Answer

Expert verified

Use multiple assignment, individual assignment, or unpacking a list/tuple.

Step by step solution

Using Multiple Assignment

In many programming languages, you can use a shorthand method to assign the same value to multiple variables at once. For example, in Python: ```python a, b, c = 5, 5, 5 ```This line of code assigns the value 5 to variables 'a', 'b', and 'c'.

Using Individual Assignment

You can assign the same value to each variable individually in separate statements. For example, in Python: ```python a = 5 b = 5 c = 5 ```This assigns the value 5 to 'a', 'b', and 'c' using three separate statements.

Using a Tuple or List to Assign

In some programming languages, you can assign the same value to multiple variables by unpacking a list or a tuple. For example, in Python: ```python values = [5, 5, 5] a, b, c = values ```This unpacks the list 'values' into the variables 'a', 'b', and 'c', with each variable receiving the value 5.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

multiple assignment

Multiple assignment is a concise way of setting multiple variables to the same value. This approach is particularly helpful in Python. You can set several variables at once in a single line of code. For example, using the syntax `a, b, c = 5, 5, 5`, you assign 5 to variables 'a', 'b', and 'c' simultaneously. This saves time and makes code more readable. Instead of writing three separate lines, you achieve the same result with just one line.

individual assignment

Individual assignment is the traditional way of assigning values to variables. In this method, you assign the same value to each variable individually. For instance, writing `a = 5`, `b = 5`, and `c = 5` in separate lines assigns 5 to 'a', 'b', and 'c' one by one. This method might seem more straightforward but can be less efficient compared to multiple assignment. Nonetheless, individual assignment makes it clear and easy to see what value is being assigned to each variable.

tuple unpacking

Tuple unpacking is an advanced feature in Python allowing you to assign values from a tuple to multiple variables. A tuple is a collection of values enclosed in parentheses, like `(5, 5, 5)`. You can unpack these values into variables using the syntax `a, b, c = (5, 5, 5)`. This is useful for handling collections of values efficiently. For lists, which are similar to tuples but are mutable, you can achieve the same effect. For example, `values = [5, 5, 5]` and then `a, b, c = values` unpacks the list into the variables 'a', 'b', and 'c'.
