根据字符串中项目的出现对列表中的项目进行排序

Question

I am a newbie to python

I have a string and list like this

s='''Hello, Carry out the item with care
Louis, MS to Dallas, TX '''

LOC=['Dallas','Louis']

How to sort the list according to the occurrence of the word from a string?

Desired Output:

LOC =['Louis','Dallas']

Considering the word in the list doesn't repeat multiple times in the string.

Answer 1

You can use the method index of strings to find the position of the occurrence, then do a sort of that list based on that, for example:

s = '''Hello, Carry out the item with care
Louis, MS to Dallas, TX '''

LOC = ['Dallas', 'Louis', 'TX', 'out']

sorted_LOC = sorted(LOC, key=s.index)

print(sorted_LOC)
>>> ['out', 'Louis', 'Dallas', 'TX']
