Ali Tarique Simple answer single = sign use to assign value like a = 2 double == sign use to check equality like 2==2 And also in some languages there is triple === sign which is use to check equality as well object type. For example 2 === '2' which is return false because 2 is int value and '2' is char value so value can be same but type is different.

single equal sign is used to set value while double equal sign is used to compare values a = 10 #a is 10 a = 12 #a is 12 now 3 == 4 #false because 3 is not equal to 4 a == 12 #true because a is equal to 12
