How to use the datetime module to get the current date and time in Python 2.x

Python provides the datetime module for processing date and time related operations. In Python 2.x versions, you can use this module to get the current date and time. The following describes how to use the datetime module in Python 2.x to get the current date and time, and provides relevant code examples.

To use the datetime module, you first need to import it:

import datetime

Then, we can use the datetime class in the datetime module to get the current date and time. The datetime class provides a now() method, which returns a datetime object representing the current date and time. The following is an example of using the now() method to obtain the current date and time:

current_datetime = datetime.datetime.now()
print("当前日期和时间：", current_datetime)

Run the above code, you will see output similar to the following:

当前日期和时间： 2022-01-01 12:34:56.789012

The output results include the current Year, month, day, hour, minute, second and microsecond information.

If you only want to get the current date or time without including other information, you can use the date() and time() methods of the datetime object. The date() method returns a date object representing the current date, while the time() method returns a time object representing the current time. The following is an example of using the date() and time() methods to obtain the current date and time:

current_date = datetime.datetime.now().date()
current_time = datetime.datetime.now().time()

print("当前日期：", current_date)
print("当前时间：", current_time)

Run the above code, you will see output similar to the following:

当前日期： 2022-01-01
当前时间： 12:34:56.789012

In the output results Contains the current date and time information respectively.

In addition to getting the current date and time, the datetime module also provides some other useful methods. For example, you can use the strftime() method to format date and time objects into a specified string representation. The following is an example of using the strftime() method to format the current date and time object into a specified format:

current_datetime = datetime.datetime.now()
formatted_datetime = current_datetime.strftime("%Y-%m-%d %H:%M:%S")

print("格式化后的日期和时间：", formatted_datetime)

Run the above code, you will see output similar to the following:

格式化后的日期和时间： 2022-01-01 12:34:56

In In the above example, "%Y-%m-%d %H:%M:%S" is a format string used to specify the date and time format. For specific formatting options, please refer to the strftime() method documentation in the official Python documentation.

By using the datetime module, we can easily get the current date and time and perform some related operations. Whether getting dates and times or formatting dates and times, the datetime module provides rich functionality and flexible methods.
