Exceptions (rare): 

Affect is sometimes used as a noun to mean the mood someone has, mainly with reference to the emotional and external factors that influence a person's ability to learn. (It is pronounced / 'ʌfekt / (uh-fect) - with the stress on the A).

Effect can be used as a verb that essentially means 'to bring something about' or 'accomplish'. For example, "Our government hopes to effect change within the anti-vaxxers' communities."
