# Basics Data Types:

'''

Các Kiểu Dữ Liệu Cơ Bản trong Python: bool, None, int, float, str

Topic #0: bool & None

'''

# [x] bool: True & False

var_bool = True

# [x] type(): Dynamically typed

# print(type(var_bool))

# Numerically, they’re evaluated as integers with value 1 (True), 0 (False)

a = 4 + True

# print(a)

b = False

# if b == 0:

# print("B is 0")

# [x] None: Phần Tử Không

var_none = None

# print(type(var_none))

# None is often used as a placeholder for optional or missing value.

# It evaluates as False in conditionals.

email_address = None # False

email_address = "codexplore@youtube.com"

# if email_address:

# print(f"Email address is {email_address}")

# else:

# print(f"Email address is empty or {email_address}")

Topic #1: Number (int & float)

'''

# [x] Numbers: int (Integer = Số Nguyên) & float (Floating point numbers = Số Thực)

print(type(1)) # int

print(type(0))

print(type(-10))

print(type(0.0)) # float

print(type(2.3))

print(type(4E2), 4E2) # 4*10(^2)

# [x] Arithmetic: Các Phép Toán: + - * / ** / // %

print(10+3) # 13

print(10-3) # 7

print(10*3) # 30

print(10**3) # 10^3 = 10*10*10 = 1000

print(10/3) # 3.3333333

print(10//3) # 3

print(10 % 3) # 1 vì 10 chia 3 = 3 dư 1

# [x] Basic Function (Hàm Cơ Bản)

print(pow(10, 3)) # 10**3 = 1000

print(abs(-6.9)) # 6.9

print(round(6.69)) # 7

print(round(5.468, 2)) # 5.47 --> round to nth digit

print(bin(512)) # '0b1000000000' --> binary format

print(hex(512)) # '0x200' --> hexadecimal format
