Control Flow

I. Conditional Statements (if, elif, else)

Used to control the flow of execution based on conditions.

Syntax:

if condition:
    # code block
elif another_condition:
    # another block
else:
    # default block

Example:

age = 20

if age >= 18:
    print("You are an adult.")
elif age > 13:
    print("You are a teenager.")
else:
    print("You are a child.")

II. Loops

  1. For Loop

Used to iterate over a sequence like a list, tuple, dictionary, or string.

names = ["Praveen", "Anusha", "Kasyap", "Keerthana"]

for name in names:
    print(name)
  1. While Loop

Repeats as long as the condition is True.

count = 0

while count < 5:
    print(count)
    count += 1

break and continue:

  • break: Exit the loop early
  • continue: Skip the rest of the loop for the current iteration
for i in range(10):
    if i == 5:
        break
    if i % 2 == 0:
        continue
    print(i)
