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。
Step 02: Create the date-time format from the strptime()directives. Step 03: Pass the string and format to the function and receive the object as output. Let’s put these steps into action. Converting a string in a specific format to a datetime object from datetime import datetime # Examp...
date_object = datetime.strptime(date_str,'%m-%d-%Y').date() print(type(date_object)) print(date_object) # printed indefault formatting Output: 输出: <class 'datetime.date'> 2018-09-19 时间对象的字符串(String to time object) We can use time() function alongwith strptime() function to...
String string = new String(); StringBuffer stringb = new StringBuffer(); for(int i=0;i<50000;i++){ stringb = stringb.append(i); } string = string + stringb; long endTime = new Date().getTime(); System.out.println("StringBuffer花费时间:"+(endTime - starTime)); } 1. 2. ...
这里的strptime(date_string,format)方法采用两个参数,它们是DateTime的字符串表示形式,在这种情况下使用的date-time格式是string_datetime。 strftime(format)方法采用一个字符串参数,该参数必须以DateTime的格式显示。 它将DateTime对象转换回字符串。 日期时间格式代码表 ...
returntime.mktime(string_toDatetime(strTime).timetuple()) #把时间戳转成字符串形式 deftimestamp_toString(stamp): returntime.strftime("%Y-%m-%d-%H", tiem.localtime(stamp)) #把datetime类型转成时间戳形式 defdatetime_toTimestamp(dateTim): ...

在Python中,可以使用内置的datetime模块将字符串转换为日期时间。以下是一个示例: ```python from datetime import datetime date_string...
