How to create a list of lists of integers from DataFrame?
dataframe, list, pandas, python
Solution
It seems they are stored as a string. Try the following (not very robust, but depending on your context it can be ok):
slist = df[['Values']].values.tolist()
ilist = [ [int(s) for s in l[0].split(',')] for l in slist]
Problem
I have Data Frame: ``` Values Values2 1,2,3,4 0,2,3 2,1,0,6 0,0,0 9,8,7,6 1,0,1 ``` I want to create list of lists. I do that in following way: ``` df[['Values']].values.tolist() ``` In output a get: ``` [['1,2,3,4'], ['2,1,0,6'], ['9,8,7,6']] ``` It's a strings but I need a lists of integer like that: ``` [[1,2,3,4], [2,1,0,6], [9,8,7,6]] ``` How can I do that?
