Python Program For Scientific Calculator (Step By Step With Code)

In this tutorial, you will learn about the Python program for scientific calculator.

In the world of mathematics and science, calculators play a crucial role in solving complex equations and performing scientific calculations.

Python allows us to create our own scientific calculator programs.

In this article, we will explore a Python program for a scientific calculator, empowering you to perform a wide range of scientific computations with ease. So, let’s dive in and unlock the potential of Python in the realm of scientific calculations!

Creating a Python program for a scientific calculator involves breaking down the functionalities of a typical calculator and implementing them using Python’s syntax and built-in functions.

At the end, there is complete code for a scientific calculator using python.

Here’s a step-by-step guide on how to create your own scientific calculator program in Python:

To begin, we need to import the necessary modules in Python that will aid us in creating the scientific calculator program.

In this case, we require the math module, which provides access to various mathematical functions and constants.

import math

A good user interface enhances the user experience. In this step, we will design a simple and intuitive user interface for our scientific calculator program.

This can be achieved using the input() function to accept user inputs and print() function to display the results.

print("Scientific Calculator")
print("1. Addition")
print("2. Subtraction")
print("3. Multiplication")
print("4. Division")
print("5. Exponentiation")
print("6. Square Root")
print("7. Logarithm")
print("8. Trigonometric Functions")
choice = int(input("Enter your choice: "))

Based on the user’s choice, we will implement the respective functionalities of the scientific calculator program using conditional statements and mathematical functions from the math module.

1. Addition

To perform addition, we will prompt the user to enter two numbers and calculate their sum.

Here is how it will work.

if choice == 1:
    num1 = float(input("Enter the first number: "))
    num2 = float(input("Enter the second number: "))
    result = num1 + num2
    print("The sum is:", result)

2. Subtraction

For subtraction, we will ask the user to input two numbers and subtract the second number from the first.

Here is how it will work.

elif choice == 2:
    num1 = float(input("Enter the first number: "))
    num2 = float(input("Enter the second number: "))
    result = num1 - num2
    print("The difference is:", result)

3. Multiplication

To perform multiplication, we will request the user to enter two numbers and multiply them.

Here is how it will work.

elif choice == 3:
    num1 = float(input("Enter the first number: "))
    num2 = float(input("Enter the second number: "))
    result = num1 * num2
    print("The product is:", result)

4. Division

For division, we will prompt the user to input two numbers and divide the first number by the second.

elif choice == 4:
    num1 = float(input("Enter the first number: "))
    num2 = float(input("Enter the second number: "))
    result = num1 / num2
    print("The quotient is:", result)

5. Exponentiation

To perform exponentiation, we will ask the user to input a base and an exponent, and calculate the result using the math.pow() function.

elif choice == 5:
    base = float(input("Enter the base: "))
    exponent = float(input("Enter the exponent: "))
    result = math.pow(base, exponent)
    print("The result is:", result)

6. Square Root

For calculating the square root, we will request the user to enter a number and compute its square root using the math.sqrt() function.

elif choice == 6:
    num = float(input("Enter the number: "))
    result = math.sqrt(num)
    print("The square root is:", result)

7. Logarithm

To calculate the logarithm, we will ask the user to input a number and the base of the logarithm.

The math.log() function will then be utilized to compute the logarithm.

elif choice == 7:
    num = float(input("Enter the number: "))
    base = float(input("Enter the base: "))
    result = math.log(num, base)
    print("The logarithm is:", result)

8. Trigonometric Functions

Lastly, for trigonometric functions, the user will be prompted to enter an angle in degrees.

We will then calculate the sine, cosine, and tangent using the respective functions from the math module.

elif choice == 8:
    angle = float(input("Enter the angle in degrees: "))
    result_sin = math.sin(math.radians(angle))
    result_cos = math.cos(math.radians(angle))
    result_tan = math.tan(math.radians(angle))
    print("Sine:", result_sin)
    print("Cosine:", result_cos)
    print("Tangent:", result_tan)

In case the user enters an invalid choice, we will display an error message and prompt the user to enter a valid choice.

else:
    print("Invalid choice. Please enter a valid option.")

Finally, we will run the program to execute the scientific calculator functionalities.

The user will be able to perform multiple calculations until they choose to exit the program.

while True:
    choice = int(input("Enter your choice (0 to exit): "))
    if choice == 0:
        print("Exiting...")
        break
    # Implement the calculator functionalities based on user's choice
