Reading a list of lists from a file as list of lists in python

Question

I collected data in the form of list of lists and wrote the data into a text file. The data in the text file looks like

[[123231,2345,888754],[223467,85645]         


        

Answer 1

You could just pickle your data instead. To save it:

>>> import pickle
>>> p= [[123231,2345,888754],[223467,85645]]  
>>> with open("data.txt", "wb") as internal_filename:
...     pickle.dump(p, internal_filename)

To load it:

>>> with open("data.txt", "rb") as new_filename:
...     pp = pickle.load(new_filename)
>>> pp
[[123231, 2345, 888754], [223467, 85645]]

This is also useful for much more elaborate objects.
