Python for Coder's Day 10: Build a Simple Calculator Using Python—Mini Project | Egnicode !!!
Description:
Welcome to Day 10 of our Python Beginner Series! 🎉 In this video, we bring everything together to create a practical Mini Project: A Simple Calculator using Python. This is your chance to apply all the key concepts we've learned so far, such as functions, loops, and conditionals, to build something useful and exciting!
🚀 What You'll Learn in This Video:
✅ Writing reusable functions for basic operations (add, subtract, multiply, divide).
✅ Using conditionals to make decisions in code.
✅ Loops for repetitive actions.
✅ Error handling to make your calculator user-friendly.
🔧 Tools Used:
Python 3.x
Any IDE of your choice (PyCharm, VS Code, or Jupyter Notebook).
💡 By the End of This Video: You'll have your very own interactive Python calculator to handle basic arithmetic operations. Perfect for beginners looking to strengthen their programming fundamentals!

Code for the Simple Calculator Project
python
Copy code
def add(a, b):
return a + b
def subtract(a, b):
return a - b
def multiply(a, b):
return * b
def divide(a, b):
try:
return a / b
except ZeroDivisionError:
return "Error: Cannot divide by zero."
def calculator():
print("Welcome to the Simple Python Calculator!")
print("Options: add, subtract, multiply, divide, quit")
while True:
operation = input("Enter an operation: ").strip().lower()
if operation == "quit":
print("Thank you for using the calculator. Goodbye!")
break
if operation in ["add", "subtract", "multiply", "divide"]:
try:
num1 = float(input("Enter the first number: "))
num2 = float(input("Enter the second number: "))
except ValueError:
print("Invalid input. Please enter numeric values.")
continue
if operation == "add"
print(f"The result is: {add(num1, num2)}")
elif operation == "subtract":
print(f"The result is: {subtract(num1, num2)}")
if operation == "multiply":
print(f"The result is: {multiply(num1, num2)}")
Elif operation == "divide":
print(f"The result is: {divide(num1, num2)}"
else:
print("Invalid operation. Please try again.")
Run the calculator
