如何删除字符串列表中的特殊字符并将其拆分为单独的元素

Question

I have a list of string like this:

list = ["A", "B", "C", "E", "0,2344 | 0,234 | 0,2345 | 0,265 | 0.2235 |"]

Output expected shoud be:

list = ["A", "B", "C", "E", "0,2344", "0,234", "0,2345", "0,265", "0.2235"]

Can anyone suggest me some ways to do this?

Answer 1

From what I understood from the comment. You can try this.

list_a=[j.strip() for i in list_a for j in i.split('|')] 

Unrelated to the question: Don't use built-in / keywords name as variable names.

Answer 2

you need:

new_list = []
for l in list1:
    y = l.split("|") 
    new_list.extend([j.strip() for j in y if j])

print(new_list)

Output:

['A', 'B', 'C', 'E', '0,2344', '0,234', '0,2345', '0,265', '0.2235']

Answer 3

You could do something like this,

lst = ["A", "B", "C", "E", "0,2344 | 0,234 | 0,2345 | 0,265 | 0.2235 |"]

output = []
for item in lst:
    if item.find("|"):
        values = item.replace("|", "").strip().split()
        for value in values:
            output.append(value.strip())
    else:
        output.append(item)

print(output)

Or better you could use list comprehension like this,

lst =[subitem.strip() for item in lst for subitem in item.split('|') if subitem]
print(lst)

And output will be,

['A', 'B', 'C', 'E', '0,2344', '0,234', '0,2345', '0,265', '0.2235']

hope this helps!

Answer 4

ans= ''.join(i for i in '["A", "B", "C", "E", "0,2344 | 0,234 | 0,2345 | 0,265 | 0.2235 |"]'. replace('|','","'));
ans= ''.join(i for i in ans. replace(',""',''))
print(ans.replace(' ',''))

above code gives expected output as written below.

["A","B","C","E","0,2344","0,234","0,2345","0,265","0.2235"]

Answer 5

Please do as follows:

   list = ["A", "B", "C", "E", "0,2344 | 0,234 | 0,2345 | 0,265 | 0.2235 |"]

   new_list = new_list = [ch.strip() for word in list for ch in word.split('|')]
   new_list.remove('')

Thanks

Answer 6

I want to remove | character in the last element of list 1 and split last element of list 1 into last 5 elements of list 2 

尝试这个

result = list[0:-1]+list[-1].replace(' ', '').strip('|').split('|')
