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...
