Python ljust rjust center输出


            看下面的例子就会明白了： 复制代码 代码如下:print '|','*'.ljust(10),'|' print '|','*'.ljust(10,'-'),'|' print '|','*'.rjust(10,'-'),'|' print '|','*'.center(10,'-'),'|' for a in range(1, 6): print 'a = '.ljust(5), repr(a).ljust(10), 'b = '.ljust(5), repr(a * 2) 输出结果: | * | | *--------- | | ---------* | | ----*----- | a = 1 b = 2 a = 2 b = 4 a = 3 b = 6 a = 4 b = 8 a = 5 b = 10
