if age >= 18: print("You are an adult.") else: print("You are a minor.") -
Loops: Allow you to repeat a block of code multiple times.
-
For Loop:
for i in range(5): print(i) # Output: 0, 1, 2, 3, 4 -
While Loop:
count = 0 while count < 5: print(count) count += 1 # Output: 0, 1, 2, 3, 4
-
5.3. Working with Functions and Modules
Functions are reusable blocks of code that perform a specific task. Modules are collections of functions and variables that can be imported into a program.
-
Defining a Function:
def greet(name): """This function greets the person passed in as a parameter.""" print(f"Hello, {name}!") greet("Alice") # Output: Hello, Alice! -
Importing a Module:
import math print(math.sqrt(25)) # Output: 5.0
5.4. Basic Input/Output Operations
Input/output operations allow a program to interact with the user. Input operations allow the user to enter data into the program. Output operations allow the program to display data to the user.
name = input("Enter your name: ")
print(f"Hello, {name}!")6. Building Projects: Hands-On Practice
