And I call it in the old place like: 我在旧的地方称它为:
ept(%self.request.get('content'))
Could anybody help me, what is wrong with my code 有人可以帮我吗,我的代码有什么问题
First of all you ought to (re-)read about string interpolation 首先,您应该(重新)阅读字符串内插法
The %
is an operator applicable to string and unicode objects, so such an object must precede its usage. %
是适用于字符串和unicode对象的运算符,因此此类对象必须先于其使用。 So you could do 所以你可以做
def ept(s):
return "%s is good" % s
ept(self.request.get('content'))
%
is applicable to integers as well, but that's a different story. %
也适用于整数,但这是另一回事。
