### **🚀 Step-by-Step Guide to Building a Python Calculator**

#### **1️⃣ Open Your Python Editor**
You can use **Jupyter Notebook, PyCharm, VS Code, or any Python environment** of your choice.

---

#### **2️⃣ Write the Python Code for the Calculator**
Here’s a simple Python script to create a calculator:

```python
def calculator():
while True:
print("\nSimple Python Calculator")
print("1. Addition (+)")
print("2. Subtraction (-)")
print("3. Multiplication (*)")
print("4. Division (/)")
print("5. Exit")

choice = input("Enter your choice (1-5): ")

if choice == '5':
print("Exiting the calculator. Goodbye!")
break

if choice in ['1', '2', '3', '4']:
num1 = float(input("Enter first number: "))
num2 = float(input("Enter second number: "))

if choice == '1':
result = num1 + num2
print(f"Result: {num1} + {num2} = {result}")

elif choice == '2':
result = num1 - num2
print(f"Result: {num1} - {num2} = {result}")

elif choice == '3':
result = num1 * num2
print(f"Result: {num1} * {num2} = {result}")

elif choice == '4':
if num2 != 0:
result = num1 / num2
print(f"Result: {num1} / {num2} = {result}")
else:
print("Error! Division by zero is not allowed.")

else:
print("Invalid input! Please enter a number between 1 and 5.")

calculator()
```

### **🔹 Explanation of the Code:**
✔ **Looping Structure:** The program runs in a loop, allowing multiple calculations until the user exits.
✔ **User Input Handling:** The program takes input from the user for numbers and operation choice.
✔ **Conditional Statements:** It checks the user’s choice and performs the corresponding arithmetic operation.
✔ **Error Handling:** Prevents division by zero to avoid runtime errors.

---

### **🔹 Enhancements You Can Make:**
🚀 Add an **exponentiation (power) function**
🚀 Include a **square root function**
🚀 Implement a **GUI-based calculator using Tkinter**

---

### **🔹 Fixing Common Errors:**
🔴 **Getting an "Invalid Input" error?**
✔ Make sure you enter numbers and not letters.

🔴 **Division by Zero Error?**
✔ The code includes a check to prevent this, but always ensure the second number isn’t zero.

🔴 **Want to exit the calculator?**
✔ Select option **5 (Exit)** to stop the program.
