1、循環
>>> test1 = ["aa","bb","cc","dd","ee","ff","gg"] >>> test1 ['aa', 'bb', 'cc', 'dd', 'ee', 'ff', 'gg'] >>> test2 = [] >>> test2 [] >>> for i in range(-1,-(len(test1)+1),-1): test2.append(test1[i]) >>> test2 ['gg', 'ff', 'ee', 'dd', 'cc', 'bb', 'aa']
2、列表分片
>>> test1[::1] ['aa', 'bb', 'cc', 'dd', 'ee', 'ff', 'gg', 'hh', 'ii', 'jj'] >>> test1[::-1] ['jj', 'ii', 'hh', 'gg', 'ff', 'ee', 'dd', 'cc', 'bb', 'aa']
3、就地反轉
>>> test1 = ["aaa","bbb","ccc","ddd"] >>> test1 ['aaa', 'bbb', 'ccc', 'ddd'] >>> test2 = test1[:] >>> test2 ['aaa', 'bbb', 'ccc', 'ddd'] >>> test1.reverse() >>> test1 ['ddd', 'ccc', 'bbb', 'aaa'] >>> test2[::-1] ['ddd', 'ccc', 'bbb', 'aaa'] >>> test2 ['aaa', 'bbb', 'ccc', 'ddd']
