First for loop stops after first iteration - Divanova94 - Apr-30-2019

I am creating a matrix array by reading two different lists with for loop. But the second for loop stops after the first iteration.
The print output is only with one parameter *1 instead of the all other that are in the lists in the list f1.

import numpy as np
f1 = [['N1M2', 'N1M3', 'N1M4', 'N1M5'], ['M1N2', 'N2M3', 'N2M4', 'N2M5'], ['N1M3', 'N1M4', 'N1M5', 'N2M3', 'N2M4', 'N2M5'], ['M1N3', 'M2N3', 'N3M4', 'N3M5'], ['N1M2', 'N1M4', 'N1M5', 'M2N3', 'N3M4', 'N3M5'], ['M1N2', 'M1N3', 'N2M4', 'N2M5', 'N3M4', 'N3M5'], ['N1M4', 'N1M5', 'N2M4', 'N2M5', 'N3M4', 'N3M5'], ['M1N4', 'M2N4', 'M3N4', 'N4M5'], ['N1M2', 'N1M3', 'N1M5', 'M2N4', 'M3N4', 'N4M5'], ['M1N2', 'M1N4', 'N2M3', 'N2M5', 'M3N4', 'N4M5'], ['N1M3', 'N1M5', 'N2M3', 'N2M5', 'M3N4', 'N4M5'], ['M1N3', 'M1N4', 'M2N3', 'M2N4', 'N3M5', 'N4M5'], ['N1M2', 'N1M5', 'M2N3', 'M2N4', 'N3M5', 'N4M5'], ['M1N2', 'M1N2', 'M1N3', 'N2M5', 'N3M5', 'N4M5'], ['N1M5', 'N2M5', 'N3M5', 'N4M5'], ['M1N5', 'M2N5', 'M3N5', 'M4N5'], ['N1M2', 'N1M3', 'N1M4', 'M2N5', 'M3N5', 'M4N5'], ['M1N2', 'M1N5', 'N2M3', 'N2M4', 'M3N5', 'M4N5'], ['N1M3', 'N1M4', 'N2M3', 'N2M4', 'M3N5', 'M4N5'], ['M1N3', 'M1N5', 'M2N3', 'M2N5', 'N3M4', 'M4N5'], ['N1M2', 'N1M4', 'M2N3', 'M2N5', 'N3M4', 'M4N5'], ['M1N2', 'M1N3', 'M1N5', 'N2M4', 'N3M4', 'M4N5'], ['N1M4', 'N2M4', 'N3M4', 'M4N5'], ['M1N4', 'M1N5', 'M2N4', 'M2N5', 'M3N4', 'M3N5'], ['N1M2', 'N1M3', 'M2N4', 'M2N5', 'M3N4', 'M3N5'], ['M1N2', 'M1N4', 'M1N5', 'N2M3', 'M3N4', 'M3N5'], ['N1M3', 'N2M3', 'M3N4', 'M3N5'], ['M1N3', 'M1N4', 'M1N5', 'M2N3', 'M2N4', 'M2N5'], ['N1M2', 'M2N3', 'M2N4', 'M2N5'], ['M1N2', 'M1N3', 'M1N4', 'M1N5']]

because you have break on line 17

Yes it should be 30x20.
But I can simplify the example. The point is to create new lists that for the elements in f1 will *1 and for the missing elements comparing to f2 will add *0.

f1 = [['N1M2', 'N1M3', 'N1M4', 'N1M5'], ['M1N2', 'N2M3', 'N2M4', 'N2M5'], ['N1M3', 'N1M4', 'N1M5', 'N2M3', 'N2M4', 'N2M5']]

f2 = ['M1N2','M1N3','M1N4','M1N5','M2N3','M2N4','M2N5','M3N4','M3N5','M4N5','N1M2','N1M3','N1M4','N1M5','N2M3','N2M4','N2M5','N3M4','N3M5','N4M5']

I don't know how I can loop correctly to solve this problem.

RE: First for loop stops after first iteration - buran - Apr-30-2019

30X20 would be 600 elements and you have 3200 (160x20). When you are reshaping, the total number of elements can’t be altered. That is why it works with break - f1 has 30 sub-lists and with brake it takes first element of each so you get 30x20 array to reshape

with the simplified example would you share what desired output would be and how it is achieved

but the desired output is:

Output:
['M1N2*0', 'M1N3*0', 'M1N4*0', 'M1N5*0', 'M2N3*0', 'M2N4*0', 'M2N5*0', 'M3N4*0', 'M3N5*0', 'M4N5*0', 'N1M2*1', 'N1M3*1', 'N1M4*1', 'N1M5*1', 'N2M3*0', 'N2M4*0', 'N2M5*0', 'N3M4*0', 'N3M5*0', 'N4M5*0']

How could I get this?

RE: First for loop stops after first iteration - buran - May-01-2019

still not sure I understand, but this will produce the desired result. requires python 3.6+

f1 = [['N1M2', 'N1M3', 'N1M4', 'N1M5']]
 
f2 = ['M1N2','M1N3','M1N4','M1N5','M2N3','M2N4','M2N5','M3N4','M3N5','M4N5','N1M2','N1M3','N1M4','N1M5','N2M3','N2M4','N2M5','N3M4','N3M5','N4M5']

new = []
for item in f2:
    for sub_list in f1:
        new_item = f'{item}*{int(item in sub_list)}'
        new.append(new_item)
print(new)

Thank you very much, but in case with two lists in f1

f1 = [['N1M2', 'N1M3', 'N1M4', 'N1M5'], ['M1N2', 'N2M3', 'N2M4', 'N2M5']]
f2 = ['M1N2','M1N3','M1N4','M1N5','M2N3','M2N4','M2N5','M3N4','M3N5','M4N5','N1M2','N1M3','N1M4','N1M5','N2M3','N2M4','N2M5','N3M4','N3M5','N4M5']
 
new = []
for item in f2:
    for sub_list in f1:
        new_item = f'{item}*{int(item in sub_list)}'
        new.append(new_item)
print(new)

It will give the output:

Output:
['M1N2*0', 'M1N2*1', 'M1N3*0', 'M1N3*0', 'M1N4*0', 'M1N4*0', 'M1N5*0', 'M1N5*0', 'M2N3*0', 'M2N3*0', 'M2N4*0', 'M2N4*0', 'M2N5*0', 'M2N5*0', 'M3N4*0', 'M3N4*0', 'M3N5*0', 'M3N5*0', 'M4N5*0', 'M4N5*0', 'N1M2*1', 'N1M2*0', 'N1M3*1', 'N1M3*0', 'N1M4*1', 'N1M4*0', 'N1M5*1', 'N1M5*0', 'N2M3*0', 'N2M3*1', 'N2M4*0', 'N2M4*1', 'N2M5*0', 'N2M5*1', 'N3M4*0', 'N3M4*0', 'N3M5*0', 'N3M5*0', 'N4M5*0', 'N4M5*0']

But I need this output:

Output:['M1N2*0', 'M1N3*0', 'M1N4*0', 'M1N5*0', 'M2N3*0', 'M2N4*0', 'M2N5*0', 'M3N4*0', 'M3N5*0', 'M4N5*0', 'N1M2*1', 'N1M3*1', 'N1M4*1', 'N1M5*1', 'N2M3*0', 'N2M4*0', 'N2M5*0', 'N3M4*0', 'N3M5*0', 'N4M5*0']

Thank you very much, It worked :)
