This is actually a c++ problem. Got no satisfying answer on comp.lang.c++.
Maybe you can help better because I know, there are many c++-converts ;).
Suppose you've got the following list (first line has field names, second
line has types and any row after is data):
csv = "name,age,place\nstring,int,string\nMac,25,Zurich\nMike,55,Oslo"
and you would like to turn it into a dictionary:
parsed = {
"name":["Mac", "Mike"],
"age":[25, 55],
"place":["Zurich", "Oslo"]
}
A trivial task in Python. In C++ it is cumbersome. I was thinking to put
the parsed data into a map:
map<string, vector<???> >
I have no problem with the key (string) but the value (vector) needs to be
of varying type. I think C++-STL does not allow what I want.
The following proposal is useless:
[...]
A simple solution, make two maps:
std::map<std::string, std::vector<std::string> > result_name;
std::map<std::string, std::vector<int> > result_age;
[...]
I want to build the map of lists dynamically - it can have many fields or
just one... and I would like to have simple interface (as Python offers).
- I cannot import python into the c++ environment (Borland Developer 2006)
and I know no one who was able to.
- I cannot write (*sigh*) the app in Python.
Any suggestions are very welcome!
Regards,
Marco (Forced to code in c++ again let me estimate the simplicity of
python)
