71 浮点数等差数列
def float_range(start, stop, n): start,stop,n = float('%.2f' % start), float('%.2f' % stop),int('%.d' % n) step = (stop-start)/n lst = [start] while n > 0: start,n = start+step,n-1 lst.append(round((start), 2)) return lst
测试举例：
float_range(1, 8, 10) # [1.0, 1.7, 2.4, 3.1, 3.8, 4.5, 5.2, 5.9, 6.6, 7.3, 8.0]
