=+ Python operator is syntactically correct -

i accidentally wrote:

total_acc =+ accuracy 

instead of:

total_acc += accuracy 

i searched net , not find anything. happened, why python think mean typing?

_{computers trust much. :)}

this same if total_acc = -accuracy, except positive instead of negative. same total_acc = accuracy though, adding + before value not change it.

this called unary operator there 1 argument (ex: +a) instead of 2 (ex: a+b).

this link explains little more.
