Question

我有一个这样的文本列表：

"DATA - Critical/Major DATA Alerts to 'DATA NM Escalation'"
"DATA - Critical/Major DATA Alerts to 'DATA NM Escalation'"
'DATA - SOM THIN Escalation'
'DATA - SOM THIN HEARTBEAT Escalation'
"DATA - Critical/Major DATA Alerts to 'DATA NM Escalation'"
"DATA - Critical/Major DATA Alerts to 'DATA NM Escalation'"
"DATA - Critical/Major DATA Alerts to 'DATA NM Escalation'"

我想从''中提取字符串的""部分。做这个的最好方式是什么？ '和"有什么区别？如您所见，一些原始文本显示为'，另一些具有"包装。

Answer 1

我有一些可行的方法，欢迎改进：

for rule in rules:
    print(rule)
    name = re.findall("'(.*)'", rule)
    if name:
        print(name[0])
    else:
        print(rule)

输出看起来像这样：（第一行输入，第二行输出。）

"DATA  - Critical/Major DATA Alerts to 'DATA  NM Escalation'"
'DATA  NM Escalation'
"DATA  - Critical/Major DATA Alerts to 'DATA  NM Escalation'"
'DATA  NM Escalation'
"DATA  - Critical/Major DATA DATA Alerts to 'DATA  NM Escalation'"
'DATA  NM Escalation'
"DATA  - Critical/Major DATA DATA Alerts to 'DATA  NM Escalation'"
'DATA  NM Escalation'
'DATA - SOM THIN Escalation'
'DATA - SOM THIN Escalation'
'DATA - SOM THIN HEARTBEAT Escalation'
'DATA - SOM THIN HEARTBEAT Escalation'
"DATA - Critical/Major DATA DATA Alerts to 'DATA NM Escalation'"
'DATA NM Escalation'
"DATA - Critical/Major DATA DATA Alerts to 'DATA NM Escalation'"
'DATA NM Escalation'

Answer 2

没有RegEx：

//A struct for temporary holding of actors (and transforms) of actors that we hit
//that don't have an ASC. Used for environment impact GameplayCues.
struct FNonAbilityTarget
{
    FGameplayTagContainer CueContainer;
    TWeakObjectPtr<AActor> TargetActor;
    FHitResult TargetHitResult;
    bool bHasHitResult;

public:
    FNonAbilityTarget()
        : CueContainer(FGameplayTagContainer())
        , TargetActor(nullptr)
        , TargetHitResult(FHitResult(ENoInit::NoInit))
        , bHasHitResult(false)
    {
    }

// (…)

输出：

lst = ["DATA - Critical/Major DATA Alerts to 'DATA NM Escalation'",
       "DATA - Critical/Major DATA Alerts to 'DATA NM Escalation'",
       'DATA - SOM THIN Escalation', 
       'DATA - SOM THIN HEARTBEAT Escalation',
       "DATA - Critical/Major DATA Alerts to 'DATA NM Escalation'",
       "DATA - Critical/Major DATA Alerts to 'DATA NM Escalation'",
       "DATA - Critical/Major DATA Alerts to 'DATA NM Escalation'"]

for element in lst:
    start_idx = element.find('\'')
    if start_idx == -1:
        start_idx = 0
    end_idx = element.find('\'', start_idx+1, len(element))
    if end_idx == -1:
        end_idx = len(element)
        print(element[start_idx:end_idx])
    else:
        print(element[start_idx+1:end_idx])

Python从双引号中提取单引号
