strptime是python datetime库中的函数,用于将一个日期字符串转成datetime日期格式便于后期处理,使用格式为datetime.strptime(date_string, format

做新专辑排序的需求时,需要对专辑的时间进行排序,由于目前该字段是字符串类型的日期,在排序函数中要转成标准的UNIX时间戳来进行对比,大概代码如下: struct tm tm1; strptime(string...18").c_str(), "%Y-%m-%d", &tm1); time_t t1 = mktime(&tm1); std::cout << t1 << endl; struct tm tm2; strptime...这里有提到说如果是从strptime()取到的值,tm_isdst的值是不确定的,必须手动指定。因此想到,是否对于未做初始化的struct tm,strptime()函数并不会去给每个值赋值。...查看strptime It is unspecified whether multiple calls to strptime() using the same tm structure will update...因此,解决方法就是在使用strptime()之前,对结构体进行零初始化(zero-initialize) struct tm tm1 = {0}; ... struct tm tm2 = {0};
一、问题 python 在单线程下调用 time.strptime(str,format) 可以正确执行,但是在多线程下会报 AttributeError: 'module' object has no...attribute '_strptime' 这个错误 二、解决 在调用 time.strptime(str,format) 这个方法的python文件中引用 '_strptime'模块 import..._strptime 编译器没有显式地调用这个模块,但是在多线程下执行strptime()方法会引用这个模块

(date_str, "%Y-%m-%d")在这个示例中,我们使用datetime.strptime()函数将日期字符串转换为日期对象。...然后,我们可以使用datetime.strptime()将日期字符串转换为日期对象,并进行后续处理。...函数首先尝试使用datetime.strptime()函数将日期字符串转换为日期对象。如果日期字符串的格式不正确,就会引发ValueError错误。...然后,我们使用datetime.strptime()函数将字符串解析为日期对象。...因此,在使用datetime.strptime()函数时,要确保日期字符串和格式字符串是一致的。
