How to sort multiple strings inside list alphabetically ascending in Python-CodePudding

I'd like to write a function which can return the sorted strings inside a list by alphabetically ascending. Like it should turn

["banana apple", "cat elephant dog"]

into

["apple banana", "cat dog elephant"].

I tried:

def apply_to_list(string_list):
   new = []
   for i in [0,len(string_list)-1]:
    data = sorted(string_list[i])
    new = data.append
    print(new)
    return new

It turned out to be wrong. I know how to sort if the list is simple, I can do:

def sort_words(string):
    words = [word.lower() for word in string.split()]
    words.sort()
    for word in words:
    print(word)
    return

However, when it comes to several strings inside each of the attribute of a list, my approach failed. Can anyone help?

CodePudding user response：

For each string, you can use str.split to get individual words sorted to sort the words join to join back the words into a single string in a list comprehension:

[' '.join(sorted(x.split())) for x in lst]

Output:

['apple banana', 'cat dog elephant']

CodePudding user response：

words = ["banana apple", "cat elephant dog"] 

s = [' '.join(sorted(word.split(' '))) for word in words]
print(s)

#['apple banana', 'cat dog elephant']

CodePudding user response：

foo = ["banana apple", "cat elephant dog"] 

def apply_to_list(myList):
    return [ ' '.join(sorted(item.split())) for item in myList ]
    
print(apply_to_list(foo))

output

['apple banana', 'cat dog elephant']
