Hello, Python Enthusiasts!

Welcome to Day 2 of my 100 Days of Python journey! Today, I delved deeper into Python’s fundamentals, focusing on data types, operations, type conversion, and the simplicity of F-Strings for string formatting. Let’s explore what I learned!

1. Understanding Python Data Types

Python offers a wide range of data types that define how data is stored and manipulated. The primary ones include:

int for integers (e.g., 19)
float for decimal numbers (e.g., 19.5)
str for strings (e.g., "Ayushi")
bool for boolean values (True or False)

By using the type() function, I can check the type of any variable:

# Checking variable data types
age = 19
name = "Ayushi"

print(type(age))  # Output: <class 'int'>
print(type(name))  # Output: <class 'str'>

Understanding these basics sets the stage for efficient data handling and manipulation.

2. Arithmetic and Logical Operations

Python allows us to perform a variety of operations on numerical data:

# Arithmetic operations
a = 10
b = 5

sum_result = a + b  # Addition
difference = a - b  # Subtraction
product = a * b     # Multiplication
division = a / b    # Division

print(f"Sum: {sum_result}, Difference: {difference}, Product: {product}, Division: {division}")

I also explored logical operators like and, or, and not to combine conditions:

# Logical operations
x = True
y = False

print(x and y)  # Output: False
print(x or y)   # Output: True
print(not x)    # Output: False

These tools are essential for building dynamic and interactive programs.

3. Type Conversion Made Easy

Python makes it straightforward to convert data between types using functions like int(), float(), and str().

Type conversion allows us to change one data type to another. This is useful when performing operations with different data types or displaying values in a specific format.

Here’s an example where I converted my age to a string for string concatenation:

# Type conversion example
age = 19
next_age = age + 1

# Converting integer to string for concatenation
print("I am " + str(age) + " years old, and next year I will be " + str(next_age) + ".")

Without str(), this would have resulted in an error. It’s crucial to ensure compatibility when combining different data types.

4. F-Strings: A Modern Way to Format Strings

One of the most powerful features I discovered today was Python's f-strings, which easily format strings with variables. Instead of concatenating strings or using string formatting methods, this allow you to embed expressions directly within string literals using curly braces {}.

# Using F-strings for string formatting
name = "Ayushi"
age = 19

print(f"My name is {name}, and I am {age} years old. Next year, I'll be {age + 1}.")
