By doing the calculator program, we will examine one of the most logical and intuitive principles in this Article. In this post, we will describe the dry run, the algorithm, and the Python code for the calculator program, which focuses on the functionality and features of the calculator.<\/p>\n

By the end of the article, the reader will be knowledgeable and proficient enough to apply a variety of mathematical operations to a few operands to obtain the desired output.<\/p>\n

Calculator Program in Python<\/h2>\n

By taking user input and displaying the output as the result of the calculation, a calculator program may be used to execute mathematical operations on two integers, including addition, subtraction, division, multiplication, and modulo.<\/p>\n

The method discussed in this article will be using simple if-else conditions to print the result output on the basis of operation selected by the user as input.<\/p>\n

Dry Run of Calculator Program in Python<\/h3>\n

Suppose we have two operands at our disposal, p and q, and we have to perform one of the following arithmetic operation discussed, namely, as follow: <\/p>\n

    \n
  1. Addition<\/li>\n
  2. Subtraction<\/li>\n
  3. Multiplication<\/li>\n
  4. Division<\/li>\n
  5. Modulo (Remainder)<\/li>\n<\/ol>\n

    hence we assign 5 to a while 3 to b, tracing out for each operation,<\/p>\n

    Addition can be stated as, a+b which results in 5+3 = 8.<\/p>\n

    Subtraction can be stated as, a-b which results in 5-3 = 2.<\/p>\n

    Multiplication can be stated as, ab which results in 5<\/em>3 = 12.<\/p>\n

    Division can be stated as, a\/b which results in 5\/\/3 = 1. The division in python with two slash characters means that integer division is being performed as a single slash would return float value.<\/p>\n

    Modulo can be stated as, a%b which results in 5%3 = 2. It reacts as a remainder finding operator in Python with its support extending to most of the programming languages.<\/p>\n

    As suggested above, any of the operations will be performed, with the result stored in a variable. On printing the result, the program is terminated successfully. <\/p>\n

    Algorithm for Calculator Program in Python<\/h3>\n

    Now that we are already through with a dry run example on all of the operations to perform for a calculator program in python which might have made it easier for you to understand its algorithm. Here is a short and concise algorithm learning up to the implementation of code for the calculator program in python.<\/p>\n

      \n
    1. Start the program<\/li>\n
    2. Take two numbers as user input using the input function<\/li>\n
    3. Take the operation to be performed using the input function<\/li>\n
    4. Use conditional logic, if-else to select the operation to perform on the two operands.<\/li>\n
    5. Store the computed value in an object named result.<\/li>\n
    6. Print the result.<\/li>\n
    7. End the program.<\/li>\n<\/ol>\n

      Code for Calculator Program in Python<\/h3>\n

      Since we are through with the algorithm and dry run part, let us look at the calculator program in python. The link to the code is attached below along with the explanation.<\/p>\n
