Get parameter to dictionary function-CodePudding

Hi i am writing program for separating values of current and voltage from serial messages from some device. I eliminate a lot of if|elif using dictionaries.I am calling function getValues from main while function and giving this function parameter msg (stored message from serial port). I have error in function def V1 that variable doesn't exist. I am new in python and still learning. Is there some option to pass msg parameter in dictionaris fuction or something similar?

def getValues(msg,typeVal,corI3,corI2,corI1):
    busValues = {'V1':V1,
                 'V2':V2,
                 'V3':V3,
                 'I1':I1,
                 'I2':I2,
                 'I3':I3,
                 'Vb':Vb,
                 'Vl':Vl,
                 'a':a,
                 'Va':Va,
                 'Ia':Ia,
                 'Ib':Ib}
    busValues.get(typeVal)(typeVal)

def V1(value):
    global index
    global strEnd1
    global strEnd2
    global strEnd3
    index = msg.find('V1:')
    strEnd1 = 30 corI3 corI2 corI1
    strEnd2 = 31 corI3 corI2 corI1
    strEnd3 = 32 corI3 corI2 corI1

CodePudding user response：

looks like you only need to add msg to your functions arguments. Same applies for cor parameters you seem to need. That would give you:

def V1(value, msg, corI3, corI2, corI1):

From there, you should be able to call it as:

busValues.get(typeVal)(typeVal, msg, corI3, corI2, corI1)
