[英]In a list, how to separate each string (with mixed special characters) into a single character?
[英]How to remove special character in a list of string and split it into separate elements
我有一個像這樣的字符串列表:
list = ["A", "B", "C", "E", "0,2344 | 0,234 | 0,2345 | 0,265 | 0.2235 |"]
預期輸出應該是:
list = ["A", "B", "C", "E", "0,2344", "0,234", "0,2345", "0,265", "0.2235"]
誰能建議我一些方法來做到這一點?
從我從評論中了解到的。 你可以試試這個。
list_a=[j.strip() for i in list_a for j in i.split('|')]
與問題無關:不要使用內置 / 關鍵字名稱作為變量名稱。
你需要:
new_list = []
for l in list1:
y = l.split("|")
new_list.extend([j.strip() for j in y if j])
print(new_list)
輸出:
['A', 'B', 'C', 'E', '0,2344', '0,234', '0,2345', '0,265', '0.2235']
你可以做這樣的事情,
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)
或者更好的是你可以像這樣使用列表理解,
lst =[subitem.strip() for item in lst for subitem in item.split('|') if subitem]
print(lst)
輸出將是,
['A', 'B', 'C', 'E', '0,2344', '0,234', '0,2345', '0,265', '0.2235']
希望這可以幫助!
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(' ',''))
上面的代碼給出了預期的輸出,如下所示。
["A","B","C","E","0,2344","0,234","0,2345","0,265","0.2235"]
請按以下步驟操作:
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('')
謝謝
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
嘗試這個
result = list[0:-1]+list[-1].replace(' ', '').strip('|').split('|')
