python - Sort criteria - sorted() -

i'd sort list following 2 criteria in order:

1. numerical order; then
2. alphabetical order.

i'm using:

from re import search my_list = ['nelsonfreire87956423', 'martha34685128', 'gleen34685128', 'polini13452678']  first_sort = sorted(my_list, key=lambda x: [x])  sorted_list = sorted(     first_sort,      key=lambda x: search(r'\d{8}', x).group() if search(r'\d{8}', x) else [] ) print(sorted_list) 

which gives desired result:

['polini13452678', 'gleen34685128', 'martha34685128', 'nelsonfreire87956423'] 

i'd know how can sort list one sorted call. mean, how can pass multiple criteria sorted?

your key function can return a tuple, elements @ each position in tuple used break ties elements @ previous position. example:

def my_key(s):     name, num = search(r'(\d+)(\d+)', s).groups()     return int(num), name 

which results in:

>>> my_key('nelsonfreire87956423') (87956423, 'nelsonfreire')  # i.e. sort on number first, name 

and therefore:

>>> sorted(my_list, key=my_key) ['polini13452678', 'gleen34685128', 'martha34685128', 'nelsonfreire87956423']
