Behavior of a conditional breakpoint in Python when using assignment -

recently debugging code , inadvertently set conditional breakpoint following:

my_var = some_val 

when in reality wanted

my_var == some_val 

obviously not want got me curious behavior when debugging (and other things happen under hood). statement executed , stored? i.e. if first line used condition my_var take on some_val every time line come across?

i noticed because hit breakpoint "condition" evaluating true.

was wondering happens beneath layer out of curiosity.

it evaluated not stored. reason because can overwrite __eq__ method, x == y function call.

short example :

class a:     def __eq__(self, other):         print "evaluated !"  = a() == 1 # prints "evaluated !"
