print(3 / 2)
# 1.5

what is // in python

"""
  '//' is floor division on python which mean
  the result will be rounded down (eg: 3.14 become 3), so
  
  '5 // 2' will be 2

! in python

#The (!) is the not operator in Python, (!=) means not equal to.
if 2!=10:
  print("2 isn't equal to 10.")
elif 2==10:
  print("2 is equal to 10.")
#Prints "2 isn't equal to 10." as 2 isn't equal to 10. Is it?

#Note that "=" is used for declarations (assign a value to a variable or change the value of one) while "==" is usually used for checking.
#Usually, "==" returns a boolean, but depends on the objects being checked if they're equal or not, that the result will be boolean.
#For example, some NumPy objects when checked will return values other than boolean (other than True or False).

#For example:

a = 10
print(a)

#will return the int 10
#Now,

print(a==10)

#will return a boolean, True as we have assigned the value of a as 10

#Another example (to make it easier and to avoid confusion) would be where

a = 10
b = 10

#and

print(a==b)

#will return a boolean, True as they're equal.

def callme(key1, key2):
  print(key1, key2)
    
obj1 ,obj2 = 6, 9
obj3 = {
  "key1": 1,

** in python

# ** means modulus. or exponent
x = 6
y = 2
print(x**y) # will print 6 raised to power 2

** in python

print(10 * 10)
# 100
print(10 ** 10)
