问题 I am looking to find the lowest positive value in an array and its position in the list. If a value within the list is duplicated, only the FIRST instance is of interest. This is what I have which does what I want but includes 0. print "Position:", myArray.index(min(myArray)) print "Value:", min(myArray) for example, as it stands if, myArray = [4, 8, 0, 1, 5] then Position: 2, Value: 0 I want it to present position: 3, value: 1 回答1: You can use a generator expression with min . This will set
