Python Frequency Counter

📂 Python Program: Count Lines in File ```python with open("file.txt") as f: lines = f.readlines() print("Total Lines:", len(lines)) ``` 💡 Log file analysis use case #Python

🔁 Python Program: Fibonacci Series ```python n = 6 a, b = 0, 1 for _ in range(n): print(a) a, b = b, a + b ``` 💡 Builds strong logic thinking #Python #Logic

🔢 Python Program: Prime Number ```python num = 7 if num > 1: for i in range(2, num): if num % i == 0: print("Not Prime") break else: print("Prime") ``` 💡 Builds logic thinking #Python #Logic

🔍 Python Program: Common Elements ```python a = [1, 2, 3] b = [2, 3, 4] common = list(set(a) & set(b)) print(common) ``` 💡 Useful in: ✔ Comparing datasets #Python

Rules to follow while writing variables in #python. 1. Variables name and only contain alpha-numeric characters and underscore ( _ ) 2. You cannot start a variable name with a number. You can use numbers in between or at the end of variable but not at starting. 3. Variables name are case sensitive. Age and age both are different. 4. A variable name cannot be any of the python keywords. These are the rules that we need to follow while declaring a variable in python.

🔢 Python Program: Even/Odd Checker ```python numbers = [10, 15, 20, 25] for num in numbers: if num % 2 == 0: print(num, "Even") else: print(num, "Odd") ``` 💡 Use case: ✔ Data filtering ✔ Log classification #Python #Programming

🔍 Python Program: Palindrome Check ```python text = "madam" if text == text[::-1]: print("Palindrome") else: print("Not Palindrome") ``` 💡 Interview classic question #Python #Coding

🐍 Python Interview Question 📌 What is Variable Scope in Python? Variable scope defines where a variable can be accessed and how long it exists in a Python program. 🔹 Local Scope Variables created inside a function and accessible only within that function. 🔹 Global Scope Variables declared outside functions and accessible throughout the program. 🔹 Module-Level Scope Variables available across the current module or file. 🔹 Built-in / Outermost Scope Predefined names provided by Python, such as len(), print(), and range(). 💡 In Short: Python follows the LEGB rule — Local, Enclosing, Global, Built-in — to resolve variable names efficiently ⚡ 👉For Python Course Details  Visit : https://lnkd.in/gf23u2Rh . #Python #PythonProgramming #VariableScope #LEGB #CodingInterview #InterviewPreparation #TechLearning #AshokIT

📁 Python Automation: Bulk File Renamer ```python import os files = os.listdir("folder_path") for i, file in enumerate(files): os.rename(file, f"file_{i}.txt") ``` 💡 Use case: ✔ Rename logs/files automatically #Python #Automation

⏰ Python Script: Run Task Every 5 Sec ```python import time while True: print("Checking system...") time.sleep(5) ``` 💡 Automation foundation #Python
