Break and Continue in Python

Break and Continue in Python: Controlling Loop Execution Break and Continue in Python: Controlling Loop Execution Loops in Python allow us to execute a block of code repeatedly. However, sometimes we need to **control** the loop's behavior—either by **stopping** it early or **skipping** certain iterations. This is where `break` and `continue` statements come in. Why Use `break` and `continue`? Efficient Loop Control: Stop loops when necessary. Skip Unwanted Iterations: Avoid unnecessary execution. Optimized Performance: Reduce iterations in large data sets. The `break` Statement The `break` statement **stops** a loop immediately when a condition is met. # Using break in a loop for num in range(1, 10): if num == 5: break # Stops the loop when num is 5 print(num) # Output: # 1 # 2 # 3 # 4 As soon as `num == 5`, the loop **terminates** completely, skipping any further iterations. The `continue` Statement The `c...

Match Statement in Python

Match Statement in Python: Simplifying Conditional Logic Match Statement in Python: Simplifying Conditional Logic The `match` statement, introduced in Python 3.10, helps structure conditional logic more efficiently compared to long `if-elif` chains. Basic Syntax of `match` Copy def get_day_message(day): match day: case "Monday": return "Start of the workweek!" case "Friday": return "Weekend is near!" case "Sunday": return "Relax, it's Sunday!" case _: return "Just another day." print(get_day_message("Friday")) Matching Multiple Values Copy match day: case "Saturday" | "Sunday": print("It's the weekend!") case _: print("A weekday.") Using Guards (Conditions) Copy match age: ...

For loop and while loop in python

For Loop in Python: Iterating Through Sequences For Loop in Python: Iterating Through Sequences The `for` loop in Python is used to **iterate through sequences** like lists, tuples, strings, and ranges. It helps automate repetitive tasks efficiently. Why Use `for` Loops? Automates repetitive operations. Makes code cleaner and more readable. Works with different data structures. Basic Syntax fruits = ["apple", "banana", "cherry"] for fruit in fruits: print(fruit) Using `range()` in a For Loop The `range()` function generates numbers for looping. for num in range(1, 6): print(num) # Output: 1, 2, 3, 4, 5 Looping Through a String for letter in "Python": print(letter) Conclusion The `for` loop is a powerful tool for iterating through sequences effortlessly. How do you plan to use it in your projects? While Loop in Python: Repeating Until a Condition is Met ...
