• Variables and Data Types: In Python, you can assign values to variables using the '=' operator. Python supports various data types, including integers, floats, strings, booleans, and more. For example:
python# Assigning values to variables
name = "John"
age = 25
height = 1.75
is_student = True
• Conditional Statements: Python provides conditional statements like if, elif, and else to perform different actions based on certain conditions. Here's an example
python# Conditional statements
if age >= 18:
print("You are an adult.")
elif age >= 13:
print("You are a teenager.")
else:
print("You are a child.")
• Loops: Python offers different types of loops, such as for and while, to iterate over a sequence of elements or repeat a block of code. Here's an example of a for loop:
python# For loop
for i in range(1, 5):
print(i)
• Functions: Functions allow you to encapsulate reusable blocks of code. You can define your own functions or use built-in functions. Here's an example of a simple function:
python# Function
def greet(name):
print("Hello, " + name + "!")
# Calling the function
greet("Alice")
• Lists: Lists are used to store multiple values in a single variable. They are mutable, meaning you can change their elements. Here's an example:
python# List
fruits = ["apple", "banana", "orange"]
# Accessing elements
print(fruits[0]) # Output: "apple"
# Modifying elements
fruits[1] = "grape"
print(fruits) # Output: ["apple", "grape", "orange"]
These are just some of the basic concepts of Python. There's a lot more to explore, such as dictionaries, tuples, file handling, and object-oriented programming. I recommend practicing these concepts and gradually expanding your knowledge as you feel comfortable.
There are many online resources, tutorials, and interactive platforms available to learn Python, such as Codecademy, Coursera, and Python's official documentation. Happy coding!
