一.python求绝对值的三种方法 1.条件判断 2.内置函数abs() 3.内置模块 math.fabs 1.条件判段,判断大于0还是小于0,小于0则输出相反数即可 # 法1:使用条件判断求绝对值 def abs_value1(): # input返回str,需转换为浮点数的格式 a = float(input('1.请输入一个数字:')) if a >= 0: a = a else: a = -a print('绝对值为:%f' % a) 2.abs()函数 # 法2:使用内置函数求绝对值…
Software-Defined Networking Network intelligence is (logically) centralized in software-based SDN controllers network operators and administrators can programmatically configure this simplified network abstraction rather than having to hand-code tens…
