🔀 Control Flow Statements

Last Updated: 13th August 2025

Definition:
Control Flow Statements decide which part of your program will run, when, and how many times. They give your program the power to make decisions and repeat tasks.

Hinglish Tip 🗣: Control Flow ka kaam hai decide karna ki program kaunsa step pehle karega, kaunsa baad me,kishko repeat karenga aur kaunsa skip karega.

Control Flow is Important ?

Without control flow, Python would just run your code line-by-line from top to bottom without any decision-making. Control flow lets you:

  • Run different code based on condition.
  • Repeat code multiple times.
  • Skip or stop parts of loop.

Example:

Imagine you are travelling:

  • Conditional: If it’s raining, take an umbrella.
  • Loop: Walk until you reach your destination.
  • Jump: If you see danger, stop immediately.

Main Categories

  1. Conditional Statements — Decision making.
  2. Looping Statements — Repeat a block of code.
  3. Transfer/Jump Statements — Change the normal sequence of execution.

Loopingfor, whileRepeat code multiple times
Jumpbreak, continue, passSkip or stop parts of loop

Code Previews:

x = 10

if x > 0:   # Conditional
    print("Positive number")

for i in range(3):  # Loop
    print(i)

for i in range(5):  # Jump example
    if i == 3:
        break
    print(i)
