《Notebook for Python》
Python is a popular and versatile programming language that is widely used in various fields such as web development, data analysis, machine learning, and more. In this article, we will introduce some useful features of Python and how to use them in your projects.
Data Types in Python
Python has several built-in data types, including integers, floats, strings, lists, dictionaries, and sets. Here is an example of how to define and use these data types in Python:
# Integers
x = 10
print(x)
# Floats
y = 3.14
print(y)
# Strings
name = "Python"
print(name)
# Lists
numbers = [1, 2, 3, 4, 5]
print(numbers)
# Dictionaries
person = {'name': 'Alice', 'age': 30}
print(person)
# Sets
fruits = {'apple', 'banana', 'orange'}
print(fruits)
Control Flow in Python
Python supports several control flow statements such as if-else, loops, and functions. Here is an example of how to use these control flow statements in Python:
# If-else statement
x = 10
if x > 5:
print("x is greater than 5")
else:
print("x is less than or equal to 5")
# Loops
for i in range(5):
print(i)
# Functions
def greet(name):
print("Hello, " + name)
greet("Alice")

In conclusion, Python is a powerful and versatile programming language that can be used for a wide range of applications. By understanding its data types, control flow statements, and other features, you can develop efficient and reliable Python programs. Remember to practice coding regularly and explore more advanced features of Python to enhance your skills further. Happy coding!
