这里是我的代码:函数调用中表现不同类VS W/O在python3类
#Check if the value has only allowed characters
def checkStr(value):
return (set(value) <= allowed)
#Enter parameter
def enterParam (msg)
value=input(msg)
if len(value) == 0:
print("Cannot be empty, try again")
enterParam(msg)
if not checkStr(value):
print("incorrect symbols detected, try again")
enterParam(msg)
return value
现在我的问题是: 此作品的脚本体内OK,但只要我放入类如下eclipse/pydev开始抱怨enterParam和checkStr没有被定义。我究竟做错了什么?
class ParamInput:
#Check if the value has only allowed characters
def checkStr(self, value):
return (set(value) <= allowed)
#Enter parameter
def enterParam (self, msg)
value=input(msg)
if len(value) == 0:
print("Cannot be empty, try again")
enterParam(msg) #<==== not defined
if not checkStr(value): #<====not defined
print("incorrect symbols detected, try again")
enterParam(msg) #<====not defined
return value
这很简单 - 非常感谢!;)从Java的到来,我忘了那。 – 2011-04-20 16:50:03
有关此行为的解释,请参阅http://stackoverflow.com/a/5467009/821378。此外,如果您不需要访问自己,通常最好将这些功能保留在模块级别,您不必使它们成为方法。 – 2012-04-02 11:02:38
