How to build a for loop identing in two different lists at the same time-CodePudding

i got a list of archives and a numpy np.array, the files in the list are the same correspondent in the numpy np.array "list"

I would like to know how to make a for loop that iterates in the items of the list like:

for i in range (list):
  get_items = (i, f) #when i is the first element in the list and f is the same in the numpy np.array

What I did so far is a for loop that iterates in the list

for i in range(list):
  get_items = the_class_i_need(i, _)

the "_" is where I got confused, because I called the numpy np.array. I know it's not working because I'm not calling the element by itself but the hole 200 itens in there. Somehow I think I was supposed to do a for loop inside a for loop but I learned what I larned all by myself and this is a hard thing to me. So thanks for the help already!!

CodePudding user response：

As mentioned above, you can iterate through your list and np array in parallel using zip() function by doing :

for i, f in zip(list_archives, np_archives):
    get_items = the_class_i_need(i, f)

For example :

list_archives = [1, 2, 3, 4]
np_archives = np.array(['A', 'B', 'C', 'D'])

for i, f in zip(list_archives, np_archives):
    print(i, f)

# Output
# 1 A
# 2 B
# 3 C
# 4 D
