Summary  
This chapter covers how to declare variables and assign values of different data types (int, float, and str) in Python and demonstrates using printing to display their contents.

General domain of usage  
Data processing

# Assigning different data types to variables in Python

age = 25            # An integer value
height = 5.9        # A float value
name = "Alex"       # A string value

print(age)
print(height)
print(name)

When you assign a value to a variable in Python, the variable stores that value in memory and remembers its type. The `int` type represents whole numbers without decimals, like `25` in the example above. The `float` type is used for numbers with decimal points, such as `5.9`. The `str` type, or string, is used for text data and is always enclosed in quotes, as seen with `"Alex"`. Each type serves a unique purpose: use `int` for counting or indexing; `float` for precise measurements or calculations with decimals; and `str` for handling names, messages, or any kind of textual information.
