Python xlrd读取excel日期类型的2种方法
有个excle表格需要做一些过滤然后写入数据库中,但是日期类型的cell取出来是个数字,于是查询了下解决的办法。
基本的代码结构
data = xlrd.open_workbook(EXCEL_PATH)
table = data.sheet_by_index(0)
lines = table.nrows
cols = table.ncols
print u'The total line is %s, cols is %s'%(lines, cols)
读取某个单元格:
table.cell(x, y).value
x:行
y:列
行,列都是从0开始
* 时间类型的转换,把excel中时间转成python 时间(两种方式)
excel某个单元格 2014/7/8
xlrd.xldate_as_tuple(table.cell(2,2).value, 0) #转化为元组形式
(2014, 7, 8, 0, 0, 0)
xlrd.xldate.xldate_as_datetime(table.cell(2,2).value, 1) #直接转化为datetime对象
datetime.datetime(2018, 7, 9, 0, 0)
table.cell(2,2).value #没有转化
41828.0
源码查看:
# @param xldate The Excel number
# @param datemode 0: 1900-based, 1: 1904-based.
xldate_as_tuple(xldate, datemode)
输入一个日期类型的单元格会返回一个时间结构组成的元组,可以根据这个元组组成时间类型
datemode 有2个选项基本我们都会使用1900为基础的时间戳
##
# Convert an Excel date/time number into a datetime.datetime object.
#
# @param xldate The Excel number
# @param datemode 0: 1900-based, 1: 1904-based.
#
# @return a datetime.datetime() object.
#
def xldate_as_datetime(xldate, datemode)
输入参数和上面的相同,但是返回值是一个datetime类型,就不需要在自己转换了
当然这两个函数都有相应的逆函数,把python类型变成相应的excle时间类型。

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

Python is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

VS Code can run on Windows 8, but the experience may not be great. First make sure the system has been updated to the latest patch, then download the VS Code installation package that matches the system architecture and install it as prompted. After installation, be aware that some extensions may be incompatible with Windows 8 and need to look for alternative extensions or use newer Windows systems in a virtual machine. Install the necessary extensions to check whether they work properly. Although VS Code is feasible on Windows 8, it is recommended to upgrade to a newer Windows system for a better development experience and security.

VS Code can be used to write Python and provides many features that make it an ideal tool for developing Python applications. It allows users to: install Python extensions to get functions such as code completion, syntax highlighting, and debugging. Use the debugger to track code step by step, find and fix errors. Integrate Git for version control. Use code formatting tools to maintain code consistency. Use the Linting tool to spot potential problems ahead of time.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

In VS Code, you can run the program in the terminal through the following steps: Prepare the code and open the integrated terminal to ensure that the code directory is consistent with the terminal working directory. Select the run command according to the programming language (such as Python's python your_file_name.py) to check whether it runs successfully and resolve errors. Use the debugger to improve debugging efficiency.

VS Code extensions pose malicious risks, such as hiding malicious code, exploiting vulnerabilities, and masturbating as legitimate extensions. Methods to identify malicious extensions include: checking publishers, reading comments, checking code, and installing with caution. Security measures also include: security awareness, good habits, regular updates and antivirus software.
