🧠 Python Data Types — GoNimbus Guide

In Python, every piece of data has a type — whether it’s text, a number, a list, or something more complex.

Understanding data types helps you write smarter, bug-free programs. Let’s explore the built-in Python data types and how to use them effectively!

📦 What Is a Data Type?

A data type defines the kind of value a variable holds and what operations can be performed on it.

For example:

• Text data can be combined.
• Numeric data can be calculated.
• Lists can store multiple values.

🏷️ Python Built-in Data Types

Python provides the following categories of built-in data types:

Category	Type Names
Text	str
Numeric	int, float, complex
Sequence	list, tuple, range
Mapping	dict
Set	set, frozenset
Boolean	bool
Binary	bytes, bytearray, memoryview
Special	NoneType

---

🔍 Checking the Data Type

Use the built-in type() function to check the type of a variable.

x = 7
print(type(x))  # Output: <class 'int'>

---

✅ Assigning Data Types Automatically

Python is dynamically typed, meaning you don’t need to declare data types explicitly — Python figures it out.

📌 Examples:

message = "Welcome to GoNimbus"    # str
score = 99                         # int
temperature = 36.6                 # float
active = True                      # bool
items = ["pen", "book", "lamp"]    # list
info = {"name": "Alex", "age": 30} # dict

---

✏️ Explicit Type Assignment

Want more control? You can manually assign the type using constructor functions:

a = str("Learning")      # string
b = int(15)              # integer
c = float(10)            # float
d = list(("red", "blue", "green")) # list
e = bool(0)              # False

📚 More Examples

Data Type	Declaration Example
str	x = "GoNimbus"
int	x = 100
float	x = 3.14
complex	x = 2 + 3j
list	x = ["apple", "banana"]
tuple	x = ("apple", "banana")
range	x = range(5)
dict	x = {"brand": "Ford", "year": 2022}
set	x = {"red", "green", "blue"}
frozenset	x = frozenset(("pen", "notebook"))
bool	x = bool(1)
bytes	x = bytes(4)
bytearray	x = bytearray(3)
memoryview	x = memoryview(bytes(5))
NoneType	x = None

🧠 Why Data Types Matter in Python

✔️ Prevents logical errors
✔️ Helps manage memory and performance
✔️ Required for advanced operations like sorting, filtering, type casting

🧪 Practice in GoNimbus Playground

Test your knowledge in real-time!

value = "42"
print(type(value))

value = int(value)
print(type(value))

🟢 Output:

<class 'str'>
<class 'int'>
