Day 6: Python Control Structures

Understanding Control Structures in Python

Control structures are fundamental features in Python that control the flow of execution in a program. Python has three main control structures: If statements, For loops, and While loops.

If Statements in Python

If statements are used to execute a block of code if a certain condition is met. They are essential for decision making in Python programming.

x = 5
if x > 0:
    print("x is positive")

Output

x is positive

For Loops in Python

For loops in Python are used to iterate over a sequence such as a list or tuple. They are perfect for automating repetitive tasks.

numbers = [1, 2, 3, 4, 5]
for number in numbers:
    print(number)

Output

1
2
3
4 
5

While Loops in Python

While loops in Python are used to execute a block of code as long as a certain condition is met. They are useful when the number of iterations is not known beforehand.

x = 5
while x > 0:
    print(x)
    x -= 1

Output

5
4
3
2
1

By understanding these control structures, you can write more efficient and effective Python code. Whether you're iterating over a list with a For loop, making decisions with If statements, or executing code until a condition is met with a While loop, control structures are an essential part of Python programming.
