After a fraction of the numerator = numerator of the previous fraction + denominator, the denominator of the next fraction = the numerator of the previous fraction, the cycle is 20 times the result. Note that the numerator is a and the denominator is B, although a = a + B,But at this point A has become a+b, so to re-assign the value of the time, it is (a+b)-B to be equal to the original denominator B, so re-assignment should be written as a-aMethod OneFrom fractionsImport fractiondef Fibonacci (
