Question

在类中创建的函数在直接调用时可以使用，但在同一类中不能与被调用一起使用。给我未定义的全局名称。

我查看了其他帖子，然后检查了方括号，间距等，但看不到该问题。

在下面的代码中有效：

test1 = srtqualifier(mdlname,datatype,dataconvention,t1)
print (test1.spartSABR())

但这不起作用：

print(test1.makequalifier()) ##NameError: global name 'spartSABR' is not defined

主要代码：

import string

datatype = "Swaption SABR Normal Volatility"
dataconvention = "USD-SIFMA Municipal Swap Index-1W-SWAPTION-PHYSICAL-SEMI-BOND"
mdlname = "IR_SABR"
t1 = 'should-send-back-none'
#datatype = raw_input("Please input Data Type: ")
#dataconvention = raw_input("Please input Data Convention: ")
#modelname = raw_input("Please provide model name: ")

class srtqualifier:
def __init__(self,mdlname,datatype, dataconvention,t1):
    self.mdlname = mdlname
    self.datatype = datatype
    self.dataconvention = dataconvention
    self.t1 = t1
    self.tempholder =  self.dataconvention.split("-")
    self.currency = self.tempholder[0]

    def spartSABR(self):
        secondpartsp = self.tempholder[1].split(" ")
        secondpartsp.append(self.tempholder[2])
        separator = "_"
        secondpart = separator.join(secondpartsp)
        secondpart = secondpart.upper()
        return secondpart

    def modelname(self):

        return dtype.get(self.datatype)

    def lastpart(self):
        td = self.t1.split("-")
        if any("PHYSICAL" in s for s in td):
            return 'PHYSICALLY_CLEARED'

            return 'ANNUAL_BOND'
        elif any("CAPLOORLET" in s for s in td):
            return 'CAPLOORLET'

    def makequalifier(self):
        qualifier = string.join([self.currency,"|",spartSABR(),"|",modelname(self.mdlname),"|",dttype(self.datatype),"|",lastpart(self.dataconvention)])
        return qualifier



test1 = srtqualifier(mdlname,datatype,dataconvention,t1)
print (test1.spartSABR())
print(test1.makequalifier())
