Python Application Based Questions

Introduction Application Questions

Explain how Python's simplicity makes it suitable for beginners compared to languages like C++.

Solution: Python's syntax is clean and uses English-like keywords, reducing the learning curve. Unlike C++ which requires managing memory and complex syntax, Python handles many low-level details automatically.

Basics Application Questions

Write a program to check if a number is even or odd using if-else.

Solution:

num = int(input("Enter a number: "))
if num % 2 == 0:
    print("Even")
else:
    print("Odd")

Intermediate Application Questions

Create a program that reads a text file and counts the number of words.

Solution:

with open('sample.txt', 'r') as f:
    content = f.read()
    words = content.split()
    print(f"Number of words: {len(words)}")

Advanced Application Questions

Implement a simple class for a Bank Account with deposit and withdraw methods.

Solution:

class BankAccount:
    def __init__(self, balance=0):
        self.balance = balance
    
    def deposit(self, amount):
        self.balance += amount
    
    def withdraw(self, amount):
        if amount <= self.balance:
            self.balance -= amount
        else:
            raise ValueError("Insufficient funds")

account = BankAccount(100)
account.deposit(50)
account.withdraw(30)
print(account.balance)  # 120
