这段python代码错在哪里了

from datetime import date
import re
class iRates:
def init(self,day,rates):
self._day=day
self._rates=rates

class ratesTable:
def init(self):
self._icon=[]
self._tcon=[]
def iadd(self,irates):
self._icon.append(irates)
def tadd(self,trate):
self._tcon.append(trate)
def getIrate(self):
return self._icon
def getTrate(self):
return self._tcon

def getIconFromTxt(self,txtFile):

with open(txtFile) as f:
for line in f:
r=re.findall(r'\d+.?\d*',line)
if r and (len(r)==10):
d=date(int(r[0]),int(r[1]),int(r[2])
#p=iRates(d,map(float,r[3:]))
self.iadd(iRates(d,map(float,r[3:])))

a=ratesTable()
a.getIconFromTxt('ls.txt')
for i in a.getIrate():
print(i._day,i._rates)

到底是代码本身有错，还是功能有错，需要描述清楚

读写的文件什么内容，程序要做什么，怎么不对，输出什么错误，什么都不说。

from datetime import date
import re
class iRates:
def init(self,day,rates):
self._day=day
self._rates=rates

class ratesTable:
def init(self):
self._icon=[]
def add(self,irates):
self._icon.append(irates)

def getIrate(self):
return self._icon
def test(self):
f=open('ls.txt')
for line in f:
r=re.findall(r'\d+.?\d*',line)
if r and (len(r)==10):
d=date(int(r[0]),int(r[1]),int(r[2])
self.add( iRates(d,map(float,r[3:])) )
f.close()

if name =='__main__':

a=ratesTable()
a.test()
for i in a.getIrate():
print(i._day,i._rates)

这是错误信息：

self.add( iRates(d,map(float,r[3:])) )
