Hi i am not able to find out the problem in my code  
’ if 1 + 1 == 3: # ∆ Make this false.  
hero.moveXY(5, 15) # Move to the first mines.

if 2 + 3 == 5: # ∆ Make this true.  
hero.moveXY(15, 40) # Move to the first gem.

# != means “is not equal to”.

if 2 + 2 == 4: # ∆ Make this true.  
hero.moveXY(25, 15) # Move to the second gem.

# \< means “is less than”.

if 2 + 2 \< 5: # ∆ Make this true.  
enemy = hero.findNearestEnemy()  
hero.attack(enemy)

if 2 \< 1: # ∆ Make this false.  
hero.moveXY(40, 55)

if True 3 = 0: # ∆ Make this false.  
hero.moveXY(50, 10)

if False 2 + 3 = 9: # ∆ Make this true.  
hero.moveXY(55, 25)`

Please format your code by surrounding it top and bottom with triple backticks ( ` )

Is not properly formatted code.

`True` is a keyword, `3` will be rendered as a number, `=` is the `assignment-operator`, and `0` is another number.

The simplest way to make `True` false would be to write it as `False` instead.

Further the `rvalue` error is a result of trying to assign a variable inside of an `if-statement`.

`=` is the assignment operator. It assigns something to something else.

`==` is a comparison (equality) operator, and checks if two things are equal.

And what are === for?  
To check is [1,53,235] equal to [1,53,235] and to compare with null?
