time.time():获取当前时间戳。time.localtime():将时间戳转换为本地时间的结构化时间。time.strftime():格式化时间为字符串。time.strptime():将字符串解析为结构化时间。time.sleep():延时操作。time.perf_counter():高精度计时。time 模块是 Python 中处理时间的基础工具,适合简单的时间操作和性能测试。对...
python中datetime模块非常好用,提供了日期格式和字符串格式相互转化的函数strftime/strptime 1、由日期格式转化为字符串格式的函数为: datetime.datetime.strftime() 2、由字符串格式转化为日期格式的函数为: datetime.datetime.strptime() 3、两个函数都涉及日期时间的格式化字符串,列举如下: %a 星期几的简写;如 星期...
We can convert a string to datetime usingstrptime()function. This function is available indatetimeandtimemodules to parse a string to datetime and time objects respectively. 我们可以使用strptime()函数将字符串转换为datetime。datetime和time模块中提供了此功能,可分别将字符串解析为datetime和time对象。 Pyt...
import datetime, time hallo_ween2016 = datetime.datetime(2016,10,31,0,0,0) while datetime.datetime.now() < hallo_ween2016: time.sleep(1) 1. 2. 3. 4. 5. 将datetime对象转换为字符串: 利用strftime()方法,可以将datetime对象显示为字符串。(strftime()函数名中的f表示格式,format) strftime(form...
即便是python资深用户也经常会错写datetime.strptime(string, format),颠倒两个参数的顺序而写成了datetime.strptime(format, string),与re.find(pattern, string)相混淆。 分析问题 1、datetime.strptime() 首先strptime的函数命名不太好, 词义模糊, 不如直接叫str2time。string是source,time是result。
