History, Scope, and Execution of Python Programming
Python is a script-based language executed directly by the Python interpreter. It is extremely easy to learn and lightweight compared to many other programming languages.
Python was originally created by Guido van Rossum to develop device driver-based applications. Today, Python has evolved into a complete ecosystem used for:
- System Software
- Application Software
- Data Science & Analytics
- Machine Learning & AI
- Interface Programming
- Game Development
- IoT & Arduino-based systems
- Automation & Testing
Python’s performance is exceptional compared to C, C++, Java, PHP, etc. It focuses on code simplicity rather than heavy structure.
🚀 How to Run Python Scripts
1️⃣ Online Mode
You can run Python without installing anything using online tools:
Example: Python Program for Addition
a = 10 b = 20 c = a + b print(c)
2️⃣ Offline Mode
Download Python from the official website:
- Download Python 3.x installer
- Run the installer (python-3.x.exe)
- After installation, Python provides default IDLE editor

Output
📘 Program: Calculate Simple Interest
p, r, t = 12000, 2.2, 3.5
si = (p * r * t) / 100
print("result is p={0} , r={1} , t={2} , si={3}".format(p, r, t, si))
# print("result is %.2f" % si)
📝 Input & Output Functions in Python
✔ Output Function: print()
print("hello") # single statement
print("hello", "world") # multiple statements
print("hello" + "world") # concatenation
print("%f" % 1.2345)
✔ Input Function: input()
var = input("message") # returns string
a = int(input("message"))
Example: Addition Program
a = int(input("Enter first number: "))
b = int(input("Enter second number: "))
c = a + b
print(c)
📚 ASSIGNMENTS
- WAP to calculate the Area of Triangle and Rectangle
- WAP to Reverse a Five-Digit Number
- WAP to Add Two Complex Numbers
✔ Solution: Reverse a Five-Digit Number
num = 78125
print("Actual number is", num)
a = num % 10
num = num // 10
b = num % 10
num = num // 10
c = num % 10
num = num // 10
d = num % 10
e = num // 10
num1 = a*10000 + b*1000 + c*100 + d*10 + e
print("Reverse of number is", num1)
✔ Addition of Complex Numbers (Without using complex())
r1 = 2
i1 = 3
r2 = 5
i2 = 7
r = r1 + r2
i = i1 + i2
print("{0}+{1}j".format(r1, i1))
print("{0}+{1}j".format(r2, i2))
print("{0}+{1}j".format(r, i))
✔ Addition Using Python Complex Numbers
num1 = 2 + 3j num2 = 4 + 5j num = num1 + num2 print(num1) print(num2) print(num)
