Convert a String to a datetime Object in Python Using datetime.strptime() In Python, we can use the datetime.strptime() method to convert a string to a datetime object. The strptime() method takes two arguments: the string to be converted and a format string specifying the input string's...
下面是一个示例代码: fromdatetimeimportdatetimedefconvert_to_datetime(date_string):format_string='%Y-%m-%d %H:%M:%S'returndatetime.strptime(date_string,format_string) 1. 2. 3. 4. 5. 在上面的代码中,我们首先定义了时间字符串的格式,然后使用strptime()函数将字符串转换为时间对象。 步骤3:处理转换...
Converting from a string Before we can do anything else, we need to convert our string to a datetime object. The main function you will use when converting a string is thestrptimefunction. This stands for String Parse Time. The strptime function takes two input variables: The date/time you ...
time1 = datetime.strptime(a,"%H%M") # convert string to time time2 = datetime.strptime(b,"%H%M") diff = time1 -time2 diff.total_seconds()/3600 # seconds to hour 不起作用。也没有 # Create datetime objects for each time (a and b) dateTimeA = datetime.datetime.combine(datetime.date...
