string-parsing

问题 I was looking to build a regex statement to always remove the first 3 lines of the string, and last 3 lines of the string (the middle part could be any n number of lines content).

问题 I am using this to split strings: let split = Str.split (Str.regexp_string " ") in let tokens = split instr in .... But the problem is that for example here is a sentence I want to parse: pop esi and after the split it turns to be (I use a helper function to print each item in the tokens list): item: popitem: item: item: item: esi See, there are three spaces in the token list.

问题 I am not a very good coder. But I really want to automate something I have to do at work. Basically, I have a bunch of placemarkers in google earth showing hand-holes of a municipal fiber network. I have a few pictures of each hand-hole that I want to place as a tag in the .kml file. Basically, I want to have it so when they click on a placemarker in google earth, it brings up the little description bubble and shows the pictures for each hand-hole and probably some other vital info. Right now

问题 I'm trying to find way to parse string that can contain variable, function, list, or dict written in python syntax separated with ",". Whitespace should be usable anywhere, so split with "," when its not inside (), [] or {}. Example string: "variable, function1(1,3), function2([1,3],2), ['list_item_1','list_item_2'],{'dict_key_1': "dict_item_1"}" Another example string: "variable,function1(1, 3) , function2( [1,3],2), ['list_item_1','list_item_2'],{'dict_key_1': "dict_item_1"}" Example output
