How to get the current date and time in Python? In the Python language, what module or class function can we call to get the current time or date?
Of course you can use the time module, which provides various time-related functions. But some functions in this module are not available on some platforms. So what to do? We
can use a more advanced object-oriented interface function: datetime. It provides a variety of simple or complex methods for manipulating dates and times.
Use the time module in python to get the current time
time.strftime(format) time.strftime("%H:%M:%S") ##24小时格式 time.strftime("%I:%M:%S")## 12小时格式
Example
A simple python program to get the date and time of the day
#!/usr/bin/python import time print (time.strftime("%H:%M:%S")) ## 12 hour format ## print (time.strftime("%I:%M:%S"))
Example output:
18:11:30 6:11:30
Python program to print out the current date
#!/usr/bin/python import time ## dd/mm/yyyy格式 print (time.strftime("%d/%m/%Y"))
Sample output:
11/10/2013
Format parameters:
%a 星期几的简写 %A 星期几的全称 %b 月分的简写 %B 月份的全称 %c 标准的日期的时间串 %C 年份的后两位数字 %d 十进制表示的每月的第几天 %D 月/天/年 %e 在两字符域中,十进制表示的每月的第几天 %F 年-月-日 %g 年份的后两位数字,使用基于周的年 %G 年分,使用基于周的年 %h 简写的月份名 %H 24小时制的小时 %I 12小时制的小时 %j 十进制表示的每年的第几天 %m 十进制表示的月份 %M 十时制表示的分钟数 %n 新行符 %p 本地的AM或PM的等价显示 %r 12小时的时间 %R 显示小时和分钟:hh:mm %S 十进制的秒数 %t 水平制表符 %T 显示时分秒:hh:mm:ss %u 每周的第几天,星期一为第一天 (值从0到6,星期一为0) %U 第年的第几周,把星期日做为第一天(值从0到53) %V 每年的第几周,使用基于周的年 %w 十进制表示的星期几(值从0到6,星期天为0) %W 每年的第几周,把星期一做为第一天(值从0到53) %x 标准的日期串 %X 标准的时间串 %y 不带世纪的十进制年份(值从0到99) %Y 带世纪部分的十制年份 %z,%Z 时区名称,如果不能得到时区名称则返回空字符。 %% 百分号
Use the datetime module to Get the current date and time
The parameters are as follows:
cur=datetime.datetime.now() cur.hour cur.minute cur.year cur.day cur.month
Example:
#!/usr/bin/python import datetime i = datetime.datetime.now() print ("当前的日期和时间是 %s" % i) print ("ISO格式的日期和时间是 %s" % i.isoformat() ) print ("当前的年份是 %s" %i.year) print ("当前的月份是 %s" %i.month) print ("当前的日期是 %s" %i.day) print ("dd/mm/yyyy 格式是 %s/%s/%s" % (i.day, i.month, i.year) ) print ("当前小时是 %s" %i.hour) print ("当前分钟是 %s" %i.minute) print ("当前秒是 %s" %i.second)
Example output:
当前的日期和时间 = 2013-10-11 19:38:19.4545 ISO格式的日期和时间 = 2013-10-11T19:38:19.4545 当前的年份 2013 当前的月份 10 当前的日期 11 dd/mm/yyyy 格式是 11/10/2013 当前小时是 0 当前分钟是 38 当前秒是 19

You can manage different Python versions by using pyenv, venv and Anaconda. 1) Use pyenv to manage multiple Python versions: install pyenv, set global and local versions. 2) Use venv to create a virtual environment to isolate project dependencies. 3) Use Anaconda to manage Python versions in your data science project. 4) Keep the system Python for system-level tasks. Through these tools and strategies, you can effectively manage different versions of Python to ensure the smooth running of the project.

The impact of homogeneity of arrays on performance is dual: 1) Homogeneity allows the compiler to optimize memory access and improve performance; 2) but limits type diversity, which may lead to inefficiency. In short, choosing the right data structure is crucial.
