python - Mapping Odd/Even to nested lists -

so i'm trying manipulate list loop. changing list string of each integer changing them or odd.

input_list = [[1,2,3], [4,5,6], [7,8,9]] 

what have outputted

input_list = [['odd','even','odd'],['even','odd','even'],['odd','even','odd']] 

this code wrote far:

for element in input_list:     item in element:         if item %2==0:         input_list[element][x]="even"     else:         input_list[element][x]="odd"         x+=1 

any appreciated.

you quite near, smallest change needed program is

input_list=[[1,2,3],[4,5,6],[7,8,9]] i,element in enumerate(input_list):     j,item in enumerate(element):         if item %2==0:             input_list[i][j]="even"         else:             input_list[i][j]="odd" print input_list 

here, i'm using enumerate instead, because can refer elements in list using indices.

you can using map , list comprehension

>>> l=[[1,2,3],[4,5,6],[7,8,9]] >>> [list(map(lambda x: 'odd' if x%2 != 0 else 'even',i)) in l] [['odd', 'even', 'odd'], ['even', 'odd', 'even'], ['odd', 'even', 'odd']] 

small note - list missing commas, [[1,2,3][4,5,6][7,8,9]] must [[1,2,3],[4,5,6],[7,8,9]]

another way use logical , operator (&) in nested list comp, padraic mentions in comments

>>> [['odd' if & 1 else 'even' in sub] sub in l] [['odd', 'even', 'odd'], ['even', 'odd', 'even'], ['odd', 'even', 'odd']]
