  • Write a program to use the identity and membership operators
  • Write a program to determine operator precedence

Exam Objectives

The following exam objectives are covered in this lab:

  • 1.3 Determine the sequence of execution based on operator precedence
  • 1.4 Select the appropriate operator to achieve the intended result

Lab Duration

It will take approximately 10 minutes to complete this lab.

Exercise 1 - Handling Operator Precedence

After learning to use arithmetic, comparison, and logical operators, now you will learn about the identity and membership operators. The membership operators are used in expressions or computations that involve a sequence of values such as lists or strings. These operators return a value of either true or false. The identity operators compare the memory locations of the variables used in expressions or computations.

When an expression in a program involves multiple types of operators, the Python interpreter evaluates the expression based on the rule of precedence. The rule specifies the order of execution of the operators used in the expression. The operators with the highest precedence will be evaluated first during execution.

In this exercise, you will perform two tasks. In the first task, you will learn to use the identity and membership operators in a Python program. In the second task, you will learn to determine the precedence of various operators during the execution of a Python program.

Learning Outcomes

After completing this exercise, you will be able to:

  • Write a program to use the identity and membership operators
  • Write a program to determine operator precedence
