Making a tiny script language using python: I need a string processing lib

I do not know if there is any lib specially designed to process the
strings in scipt language.
for example:
I hope to process the string"print a,b,c,d,e "in the form"command
argumentlist" and return:
{'command'='print',
'argumentlist'=['a','b','c','d','e']}
Are there any lib to implement this?


Ideally , the lib should have a function like below:

def extract(commandstring, splitformat)

eg:
extract("see#you at tonight","what#whom at when")
return: {"what":"see","whom":"you","when":"tonight"}

extract("1;2;3;4;5","list[;]")
return: {"list":['1','2','3','4','5']}

extract("print a,b,c,d,e","command arglist[,]")
return: {"command":"print","arglist":['a','b','c','d','e']}

extract("fruit:apple~orgrange~pear~grape#name:tom;sam;dim;ham"
         ,"class1:instance1[~]#class2:instance2[;]")
return: {"class1":"fruit",
         instance1:['apple','orange','pear','grape'],
         "class2":"name",
         "instance2":['tom','sam','dim','ham']
         }
