将列表的拆分字符串表示形式转换为字符串

Question

我已经阅读了删除列表中的字符“u”，但在我的情况下它不起作用：

[u"[u'DUTY,", u'RHODE', u'ISLAND', u'STATE', u'ASSOCIATION', u'OF', u'FIRE', u"OF']"]

**Expected Output** : DUTY RHODE ISLAND STATE ASSOCIATION OF FIRE OF

如果我使用：

list = [u"[u'DUTY,", u'RHODE', u'ISLAND', u'STATE', u'ASSOCIATION', u'OF', u'FIRE', u"OF']"]

new_list = "%s, %s" % (list[-1], ' '.join(list[:-1]))

Output will : u"OF'], [u'DUTY, RHODE ISLAND STATE ASSOCIATION OF FIRE FIGHTERS LINE"

如果

next_list = [str(' '.join(filter(None, new_list)))]
Output is: ["[u'DUTY, RHODE ISLAND STATE ASSOCIATION OF FIRE FIGHTERS LINE OF']"]

如果：

import ast
ast.literal_eval(' '.join(list))[0]

Output is : u'DUTY, RHODE ISLAND STATE ASSOCIATION OF FIRE FIGHTERS LINE OF'

谢谢

Answer 1

您应该可以使用ast.literal_eval 快速完成此操作：

import ast

s = ["[u'DUTY,", 'RHODE', 'ISLAND', 'STATE', 'ASSOCIATION', 'OF', 'FIRE', "OF']"]
out = ast.literal_eval(' '.join(s))[0]

print(str(out)) # the str bit is redundant for python3
'DUTY, RHODE ISLAND STATE ASSOCIATION OF FIRE OF'
