Control Flow - If, Loops, and Conditionals

Control Flow Structures

If Statements

Make decisions in your code based on conditions.

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

For Loops

Iterate over sequences like lists and ranges.

for i in range(5):
    print(f"Number: {i}")

names = ["Alice", "Bob", "Charlie"]
for name in names:
    print(f"Hello, {name}!")

While Loops

Execute code as long as a condition is true.

count = 0
while count < 5:
    print(f"Count: {count}")
    count += 1

Best Practices

• Use meaningful variable names
• Keep conditions simple and readable
• Avoid infinite loops
• Use break and continue wisely
