Understanding Data Types

Data types are the building blocks of any programming language. They define what kind of data can be stored and manipulated within a program. Understanding data types is crucial for writing efficient and effective code.

Common Data Types

Here are some of the most common data types:

Integer: Whole numbers, like 5, -3, or 42.
Float: Numbers with a decimal point, like 3.14 or -0.001.
String: Textual data, like "Hello, world!" or "The quick brown fox".
Boolean: True or false values.

Examples

Let's see how these data types work in practice:

Integer:
```
age = 25
print(age)
```
Float:
```
pi = 3.14159
print(pi)
```

String:

name = "Alice"
print("Hello, " + name + "!")

Boolean:
```
is_valid = True
print(is_valid)
```

Data Type Conversion

Sometimes, you might need to convert one data type to another. For example, converting a string to an integer:

age_str = "25"
age_int = int(age_str)
print(age_int)
