标签: python string python-3.x

class Direction:
    def __init__(self,position=0):
        self.position=position
        self.dir=1
    def display(self):
        print("Positon:",self.position,",Direction: Up")

现在正在打印什么:

 >>> a=Direction(3)

 >>> a.display()

 Positon: 3 ,Direction: Up

我想删除3之后的空格。

使用a = catch_error(nokodoc) do |doc| doc.search('#element-1').attribute('href').text end def catch_error(doc) yield doc rescue => ex puts doc.title # Or something else that identifies the document puts ex.message puts ex.backtrace.join("\n") end 。您的rescue函数如下所示:

像这样:

>>> print("Position: ", self.position, ", Direction: Up", sep='')
Position: 3, Direction: Up

或者:

>>> print("Position: %s, Direction: Up" % self.position)
Position: 3, Direction: Up
