for more concise indexing, just a suggestion i learned from my professor today, you can iterate like this: for idx, num in enumerate(list_of_nums)

I have a list of list of list in Python data. All values are corresponding to each species in the data. I wanna extract values of specific species. Each corresponding value is in each list.

Suppose I have three species Cu, Ag, Au and Pt. At three different temperatures their frequencies are given as:

Frequency = [[{1}, {2}, {3}, {4}], [{1}, {22}, {44}, {54}], [{23}, {43}, {52}]

Remember the third value of each list is for "Au" which are 3, 44, 43. so, I need answer like [3, 44, 43].

How can i make a new list that looks like the old one and change it without changing the the old one ????

f you had a list of numbers how could you group every set of 4 numbers together? so if you had 12 numbers you would have 3 lists of 4.
