Can u somebody explain == is?

Question

I just forgot

Answer 1

It is the “equal” operator. It outputs true if the values compared are equal and false if not.
Example:

1==1 //true

1==2 //false

a=5
a==5 //true

Answer 2

In short it's equal to operator 🙇🏻‍♂️

Answer 3

' = ' operator is used as an assignment operator, to assign values to variables,
arrays etc.
'==' operator is used to check equality between things (variables, constants etc.)

Example :
=========
Python
=========
a=5
if a==5 :
print "Variable 'a 'contains 5"
else :
print "Variable 'a ' does not contain 5"
============
Here when I write a=5 it means I have assigned value to the variable' a' that is 5
__________________________________________________________________
But when I check if condition I check the equality between variable a and in this case 5, which is true as a=5 (a is already assigned 5 ) and the output will be "Variable 'a 'contains 5"
__________________________________________________________________
But when change the condition to if a==789 : this will give the output "Variable 'a ' does not contain 5" of the else block because the condition then a==5 isn't true that is a is not equal to 5 and that's what a' ==' operator does check equality, it can be used in lot many ways in programs not only limited to if-else statements as I showed.

Answer 4

It is an equal operator. Which is used in boolean operation specially. In mathematics we use '=' for equal right? But in programming language we call single equal sign: '=' as a assignment operator, instead we use double equal sign: '==' for equality. I add a short note with it. After declaring a variable while we using single equal sign, like. See my code:

The values of c is alternate 😊 We can handle the value of a variable while we declared a variable using assignment operator. It means, a has literally change its value you see above. But when we declared a variable using double equal sign we can't change its value like this. And we basically use equal sign for boolean operation to compare the value of variable which assigned.
