Variables in Python
Variables are dynamically typed in Python.
Python is case sensitive; it differentiates between capital (Erbil) and small letters (erbil).
The first letter of variables cannot start with digits (i.e. 3Erbil).
Main data types in Python
- Integers:
int
Age = 55
type(Age) # class 'int'
2- Floats: float
x = 22.5
type(x) # class ‘float’
3- Complex: complex
z = 5 + 10j
type(z) # class 'complex'
4- Boolean: bool is true or false
isFactor = False
type(isFactor) # class 'bool'
5- Strings: str
name = "Anas"
type(name) # class 'str'
6- Nothing: NoneType
precipitation = None
type(precipitation) # class 'NoneType'
Container data types in Python:
1- Tuple: tuple
color = ("red", "blue", "green")
type(color) # class 'tuple'
2- List: list
Color = ["red", "blue", "green"]
type(Color) # class 'list'
3- Set: set
food = set(["rice" , "egg", "yogurt"])
type(food) # class 'set'
4- Dictionary: dict
age = {'Anas': '8', 'Aviar': '6', 'Muhammad': '5'}
type(age) # class 'dict'
5- Range: range
y = range(100)
type(y) # class 'range'
