creating a numpy array from lists with list names

Question

Hi,

I would like to create a list of lists (numpy array) with list names, mean and list length.

Example:
list1 = [1,2,3]
list2 = [4,5,6,7,8]
list3 = [7,8,9,10,11,12,13]

Code:

list_of_lists = [list1, list2, list3]
final_numpy = ['list_name', 'mean', 'list length']

for each in list_of_lists:
final_numpy.append([..., mean(each), len(each)])

I would like to have an output like this:
final_numpy = [['list_name', 'mean', 'list length'], ['list1', 2, 3], ['list2', 6, 5], ['list3', 10, 7]]

I am almost there but don't know how to include the list name in the loop.

please help

+Marek Kluczewski i literally re-wrote it for you already lol

Answer 2

Thank you for your help.

I have a question though. Is there an automated way to include list names as strings? I thought that maybe there is a function which can get the list name from the list while looping through various it.

Answer 3

+Marek Kluczewski It's not possible. Names hold references to memory, but memory does not hold references to names which reference them.

Here i rewrote the code for you and it's working :-)

The problem is when you have the name of a list in another list, the list item is replaced with the contents of the list. For example,

print(list_of_lists[list1])

is the same as:

print(list1)

What do you mean exactly? I haven't tried it
