How to sort my list by descending numbers and ascending alphabet?-CodePudding

I want to sort a list of lists

l = [[2, 'Horror'], [2, 'Romance'], [2, 'Comedy'], [3, 'Action'], [1, 'Adventure'], [2, 'History']]

and want this output that sort first by numbers in descending order and then by alphabet in ascending order:

[[3, 'Action'], [2, 'Comedy'], [2, 'History'], [2, 'Horror'], [2, 'Romance'], [1, 'Adventure']]

but I receive this using sorted(l, reverse=True):

[[3, 'Action'], [2, 'Romance'], [2, 'Horror'], [2, 'History'], [2, 'Comedy'], [1, 'Adventure']]

CodePudding user response：

We can sort using a lambda function:

lst = [[2, 'Horror'], [2, 'Romance'], [2, 'Comedy'], [3, 'Action'], [1, 'Adventure'], [2, 'History']]
output = sorted(lst, key=lambda x: (-x[0], x[1]))
print(output)

# [[3, 'Action'], [2, 'Comedy'], [2, 'History'], [2, 'Horror'], [2, 'Romance'], [1, 'Adventure']]

CodePudding user response：

you can sort like this,

test_list = ["1", "G", "7", "L", "9", "M", "4"]

print("The original list is : " str(test_list))

numerics = []

alphabets = []

for sub in test_list:

if sub.isnumeric():

    numerics.append(sub)
else:
    alphabets.append(sub)

res = sorted(alphabets) sorted(numerics)

print("The Custom sorted result : " str(res))
