Concept 2: Understanding Concept 2 with Examples

Welcome to Concept 2 in the Understanding the Key Concepts lesson!

In this concept, we will delve into Concept 2 and gain a deeper understanding through examples.

Concept 2 is about control flow statements in programming.

Control flow statements allow us to control the execution of our code based on specific conditions. These statements include if-else, switch, while, and for statements that determine the flow of the program based on certain conditions or iterations.

Let's take an example to illustrate the use of control flow statements in Python:

1if __name__ == "__main__":
2  # Python logic here
3  for i in range(1, 101):
4    if i % 3 == 0 and i % 5 == 0:
5        print("FizzBuzz")
6    elif i % 3 == 0:
7        print("Fizz")
8    elif i % 5 == 0:
9        print("Buzz")
10    else:
11        print(i)
12
13  print("Print something")

In this example, we use control flow statements to print the numbers from 1 to 100. However, if a number is divisible by 3, we print "Fizz", if it is divisible by 5, we print "Buzz", and if it is divisible by both 3 and 5, we print "FizzBuzz".

Understanding control flow statements is essential as they enable us to create more dynamic and complex programs by controlling the flow of execution based on specific conditions or iterations.

Next, we will explore more advanced concepts related to control flow statements, such as nested if-else statements, loops, and control flow optimization techniques.

if __name__ == "__main__":

  # Python logic here

  for i in range(1, 101):

    if i % 3 == 0 and i % 5 == 0:

        print("FizzBuzz")

    elif i % 3 == 0:

        print("Fizz")

    elif i % 5 == 0:

        print("Buzz")

    else:

        print(i)

  print("Print something")
