Help required over a confusion

Hi, I just want to know that why we don't use == operator with while / for loop?

Feel free to use == any where an equality check is needed.

Thanks but pycharm is showing error while using this in a code ;

1 2 3

x=0 while (x>==0):     print(x)

[Yoriz]

Because that is not == you want just >= not >==.

That's the reason i m getting confuse ..
scenarios are;
1) if we use while (x==10)----it works perfectly.
20 But if we use while (x<=10)-----this shows error to not to use double is equal to sign.

Confusion is why we dont use double == sign while using with another operator whereas if we use == independently
then no error...

== is used to distinguish the operator from assignment, where = is used. We don't need to distinguish >= from =, because they are obviously different, so we don't use >==.

Maybe your thinking because < is less than and == is equal that you could combine them to make less than or equal.
They are set symbols that are used individually.

#Operation Meaning <          #strictly less than <=         #less than or equal >          #strictly greater than >=         #greater than or equal ==         #equal !=         #not equal is         #object identity is not     #negated object identity

Thanks Sir, got the point.
