python - The differences' between the operator "==" and "="

Question

The differences' between the operator "==" and "=". When would each be used? Why would each be used?

Answer 1

In python and other languages like C, 
     "=" is a assignment operator and is used to assign a value to a variable.
       Example: a=2 # the value of a is 2

whereas "==" is Comparison operator and is used to check whether 2 expressions give the same value .Equality check returns true if it succeeds and else return false.
  Example: a=2 b=3 c=2 
             a==b (#false because 2 is not equal to 3) 
               a==c (#true because 2 is equal to 2)
