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)
