Split value of string within array of arrays in Python
arrays, python
Solution
If you want to do it inplace:
In [83]: arr = [['PROVEEDOR', '0-6', '11111'], ['tiempo ida pulidor', '6-14', '33333']]
In [84]: for i in arr:
...: i[1:2]=i[1].split('-')
In [85]: arr
Out[85]: [['PROVEEDOR', '0', '6', '11111'], ['tiempo ida pulidor', '6', '14', '33333']]
Problem
I've an arrays of arrays called `arr` and I want to split the second value of each array. This means, if I've `0-6` I would like to modify it to `'0','6'` What I have: ``` arr = [['PROVEEDOR', '0-6', '11111'], ['tiempo ida pulidor', '6-14', '33333']] ``` What I would like to have: ``` arr = [['PROVEEDOR', '0', '6', '11111'], ['tiempo ida pulidor', '6', '14', '33333']] ``` How can I do this conversion? It's always the second value, and always have two numbers. I know I've to use `.split('-')` but I know dont know to make it work here to make the replacement, as I've to iterate between all the arrays included in `arr`. Thanks in advance.
