Python Calculator - Building a Simple Calculator Program in Python
Welcome to our Python tutorial series! In this short video, we'll guide you through the process of building a simple calculator program using Python. With a focus on clarity and brevity, we'll cover the essential concepts to create a functional calculator.
Python Calculator:
Learn how to create a basic calculator program that can perform addition, subtraction, multiplication, and division operations. Follow along as we explain each step, from input validation to operator checks and result output.
Key Topics Covered:
Prompting the user for a mathematical expression
Validating the input format and providing instructions for correct expression formatting
Splitting the expression into operands and operator
Converting the operands to floating-point numbers
Checking the operator and performing the corresponding arithmetic operation
Handling invalid operator inputs gracefully
Displaying the result of the calculation

print('Ex. 1 * 1')
while True:
user_input = input("Enter a mathematical expression: ")
if user_input == 'q':
break
else:
operands = user_input.split()
if len(operands) != 3:
print("Invalid input! Please provide an expression in the format: 1 + 1")
else:
num1 = float(operands[0])
operator = operands[1]
num2 = float(operands[2])
if operator == '+':
result = num1 + num2
elif operator == '-':
result = num1 - num2
elif operator == '*':
result = num1 * num2
elif operator == '/':
result = num1 / num2
else:
print("Invalid operator! Please use +, -, *, or /")
print(f"Result: {result}")
