from a list of numbers to a list of lists with integers and tuples-CodePudding

from a list of numbers how can I go through the list by taking five numbers for iteration and placing the first two as variables and the last three inside a tuple? i have the list

['20','15','45','76','0','67','45','485','16','8']

i want a = 20 , b = 15 and t = ('45','76','0') then i want a = 67 , b = 45 and t = ('485','16','8') and put them into a list. as a result I would have

[['20','15',('45','76','0')],['67','45',('485','16','8')]]

i really don't know how iterate 5 items every time

>>> l = ['20','15','45','76','0','67','45','485','16','8']
>>>
>>> for k in range(0,len(l),5):
...     print(l[k], l[k 1], l[k 2:k 5])
20 15 ['45', '76', '0']
67 45 ['485', '16', '8']
>>>

You can use a simple list comprehension:

l = ['20','15','45','76','0','67','45','485','16','8']

N = 5
[[l[i],l[i 1],tuple(l[i 2:i 5])]for i in range(0, len(l), N)]

output:

[['20', '15', ('45', '76', '0')],
 ['67', '45', ('485', '16', '8')]]
