Question

i have a class (cls) with 2 main strings (str1, str2) and a list of strings (strlist)

python makes the strlist into a tuple so when i want to append to it i use

tmp=list(strlist)
tmp.append(addToList)
self.list=tmp

may not the best option but its the only one i could make with low knowledge of python

now i make things more complicated
i have list of cls (clslist) and i want to add another string to the strlist where str1 = A && str2 = B

how do create a search that will search for a match in the clslist and if found will add the new string to strlist

EDIT 1

class cls ():
    def __init__ (self,str1,str2,strlist):
        self.str1 = str1
        self.str2 = str2 
        self.strlist = strlist

and the main

def main():
    clslist =[]
    clslist.append(cls ("aaa","bbb",("123","456"))

i want to find the cls in the clslist where str1 = aaa and str2 = bbb and then add another string to the str list

so i will end up like this (“aaa”,”bbb”,(“123″,”456″,”789”))

Answer 1

Since clslist is unsorted your search will need to be linear.

For example:

for i in clslist:
    if i.str1 == A and i.str2 == B:
        i.strlist.append(whatever)
