My script contains 4 classes and 1 interface. I have a method generateID
which generate an ID according to outputmode
, a mode (modeCB
) and a dataframe (data_h_f
). When I execute my class I have this error :
TypeError: generateID() takes 3 positional arguments but 4 were given
I'm beginner in python especially objected oriented programming, I don't know if the design of my script is good. I have 3 arguments for my method generateID()
and 3 parameters everywere.
class OutputMode(object):
def __init__(self,name,startTime,intervalSeconds,timezone):
...
class IDCalculation_I:
def generateID(outputMode,modeCB,data_h_df):
pass
class IDCase1(IDCalculation_I):
def generateID(outputMode,modeCB,data_h_df):
...
class Fingerprinter(object):
def __init__(self,outputMode,modeCB=CONST_MODE_CONT):
self._modeCB = modeCB
self._outputMode = outputMode
def generateID(outputMode,modeCB,data_h_df):
pass
def run(self):
return self.generateID(outputMode,modeCB,data_h_df)
def main():
outputMode = OutputMode('EEA','06:00',8*3600,pytz.timezone('Europe/Paris'))
f1 = Fingerprinter(outputMode, CONST_MODE_CONT)
t = f1.generateID(outputMode,CONST_MODE_CONT,data_h_df)
if __name__ == '__main__':
main()

You forgot to add self
. Or use @staticmethod
decorator if you don't want to add self
.
class IDCalculation_I:
@staticmethod
def generateID(outputMode,modeCB,data_h_df):
pass
class IDCase1(IDCalculation_I):
@staticmethod
def generateID(outputMode,modeCB,data_h_df):
...
class Fingerprinter(object):
def __init__(self,outputMode,modeCB=CONST_MODE_CONT):
self._modeCB = modeCB
self._outputMode = outputMode
@staticmethod
def generateID(outputMode,modeCB,data_h_df):
pass
def run(self):
return self.generateID(outputMode,modeCB,data_h_df)
