how to find index of int in a string? exceptions?

[Shaun]

ok,
i have variables ,id ,subId, nvSeqStr
a message will be passed in like...(some code  & pseudo code below)
forgive me im still a newbie and i cant grasp this stuff at all....


class message:
    import string
 
    def __init__(self, id, subId, nvSequence):
        self.id=id
        self.subId=subId
        self.nvSequence=nvSequence()
        
         #overloaded constructor 1
 #sets up member vars id and subId subId of type int
    def __init__(self, id, subId, nvSequence=None):
        self.id = id
        self.subId = subId
        self.nvSequence = nvSequence

def Message(StringMsg):

# what i want to do is,

1) find the index of the first integer in the string StringMsg
2)          #on an error throw a  format exception
3)    save int in var id

4) find the index of the second integer in the string StringMsg            
            #on an error throw a  format exception
    save int in var subId

5) keep the rest of the string in var nvSeqStr

6)    if nvSeqStr is not empty
7)        try
            decode it
                    #on an error throw a  format exception
8)        else
            set nvSeqStr to null
                    #on an error throw a  format exception
