#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.Copyright © 2021 Codeinu
