#                                   DATA TYPES
#--------------------------------------------------------------------------------------
# Python automatically detect data types, so you don't need to declare it
# Data Types can change any time!
#======================================================================================


# Data Types
# ---------------------------------------------------
# No Value    |   Single value     |   Multi values |
# ---------------------------------------------------
# none        |   int,float,       |   list,set,    |
#             |   str,bool         |   tuple, dict  |
#----------------------------------------------------

#--------------------------------------------------------------------------------------
# Basic data types in python
#--------------------------------------------------------------------------------------


#--------------------------------------------------------------------------------------
# int: integer:whole number without decimals
#--------------------------------------------------------------------------------------
a = 10
print(a, type(a))

#--------------------------------------------------------------------------------------
# float: numbers with decimal points
#--------------------------------------------------------------------------------------
b = 3.15  
print(b, type(b))


#--------------------------------------------------------------------------------------
# String: Represent text or a sequence of characters
# written inside single or double quotes
#--------------------------------------------------------------------------------------
c = "Hello"     # str
d = 'Hi'        # Str
e = "1234"      # str
print(c, type(c))
print(d, type(d))
print(e, type(e))

#--------------------------------------------------------------------------------------
# Boolean: Can be either True or False
# used to handle logic and decision-making
# True or False are case-sensitive;they must start with a capital letter
f = True        #bool
g = False       #bool
print(f, type(f))
print(g, type(g))

#--------------------------------------------------------------------------------------
# none: means "no value", "nothing" or "unknown"
#--------------------------------------------------------------------------------------
h = None
print(h, type(h))

i = ""          # str - Blank
j = " "         # str - Empty Space
print(i, type(i))
print(j, type(j))

# Summary
#--------------------------------------------------------------------------------------
# Each value has a data type (this helps python decide how to handle the value)
# It automatically detects data types
# Dynamic: Data Types can change anytime
# 3 Categories
#   No value        :- NoneType
#   Singe Value     :- int,str,bool,float,complex
#   Multiple Values :- set,tuple,dict,list
# Values are objects of data type class
