How do I convert this string which is a list into a proper list?
mylist = "['KYS_Q5Aa8', 'KYS_Q5Aa9']"
I tired this but its not what I was expecting:
print mylist.split()
["['KYS_Q5Aa8',", "'KYS_Q5Aa9']"]
I'd like it like this:
['KYS_Q5Aa8','KYS_Q5Aa9']
Pass the List<String> as a parameter to the constructor of a new ArrayList<Object> . List<Object> objectList = new ArrayList<Object>(stringList);
The most pythonic way of converting a list to string is by using the join() method. The join() method is used to facilitate this exact purpose. It takes in iterables, joins them, and returns them as a string.
Use literal_eval from the ast module:
>>> import ast
>>> ast.literal_eval("['KYS_Q5Aa8', 'KYS_Q5Aa9']")
['KYS_Q5Aa8', 'KYS_Q5Aa9']
Unlike eval
, literal_eval is safe to use on user strings or other unknowns string sources. It will only compile strings into basic python data structures -- all others fail.
Alternatively, if your string is just like that (ie, no embedded commas or meaning to parse inside the sub quoted strings) you could coerce split to do what you want do too:
>>> mystring = "['KYS_Q5Aa8', 'KYS_Q5Aa9']"
>>> [e.strip("' ") for e in mystring.strip('[] ').split(',')]
['KYS_Q5Aa8', 'KYS_Q5Aa9']
