# boolean valuez always gives true or false

# print(10 > 9)
# print(10 == 9)
# print(10 < 9)

#  bool(_)  function can evaluate any value
# print(bool("hello"))
# print(bool(7))

# print(bool(0))

# these are mostly true until they are nil , empty , or 0 .

# class myclass:
#   def __len__(self):
#     return 0

# obj = myclass
# print(bool(obj))


# def fun():
#   return True

# print(fun())

# x  = 20

# print(isinstance(x,int))


# print(5> 3)

# print(bool("abc"))

# print(bool(0))

# operators are uaed to perform operations on values and variables.

# print(2**3)  #exponention operator

# print(3//2)

# x = 5
# x &= 3
# print( x)


# print(x:=3)


# x |= 4
# print(x)

# x += 3
# print(x)

# list is used to store multiple items in a single variables

# list are changeable , ordered , allow duplicate value .

# l = ["rahul" , 49 , " yadav"]
# print(l)
# print(len(l))
# print(type(l))

# x = ["rao"]
# l.extend(x)
# print(l)
