python读取excel表数据的方法:
1、安装Excel读取数据的库-----xlrd
直接pip install xlrd安装xlrd库
#引入Excel库的xlrd import xlrd
2、获取Excel文件的位置并且读取进来
#导入需要读取Excel表格的路径 data = xlrd.open_workbook(r'C:\Users\NHT\Desktop\Data\\test1.xlsx') table = data.sheets()[0]
3、读取指定的行和列的内容,并将内容存储在列表中(将第三列的时间格式转换)
#创建一个空列表,存储Excel的数据 tables = [] #将excel表格内容导入到tables列表中 def import_excel(excel): for rown in range(excel.nrows): array = {'road_name':'','bus_plate':'','timeline':'','road_type':'','site':''} array['road_name'] = table.cell_value(rown,0) array['bus_plate'] = table.cell_value(rown,1) #将Excel表格中的时间格式转化 if table.cell(rown,2).ctype == 3: date = xldate_as_tuple(table.cell(rown,2).value,0) array['timeline'] = datetime.datetime(*date) array['road_type'] = table.cell_value(rown,3) array['site'] = table.cell_value(rown,4) tables.append(array)
4、运行程序
if __name__ == '__main__': #将excel表格的内容导入到列表中 import_excel(table) #验证Excel文件存储到列表中的数据 for i in tables: print(i)
5、最终的运行效果如下:
6、完整的程序代码:
import xlrd from xlrd import xldate_as_tuple import datetime #导入需要读取的第一个Excel表格的路径 data1 = xlrd.open_workbook(r'C:\Users\NHT\Desktop\Data\\test.xlsx') table = data1.sheets()[0] #创建一个空列表,存储Excel的数据 tables = [] #将excel表格内容导入到tables列表中 def import_excel(excel): for rown in range(excel.nrows): array = {'road_name':'','bus_plate':'','timeline':'','road_type':'','site':''} array['road_name'] = table.cell_value(rown,0) array['bus_plate'] = table.cell_value(rown,1) if table.cell(rown,2).ctype == 3: date = xldate_as_tuple(table.cell(rown,2).value,0) array['timeline'] = datetime.datetime(*date) array['road_type'] = table.cell_value(rown,3) array['site'] = table.cell_value(rown,4) tables.append(array) if __name__ == '__main__': #将excel表格的内容导入到列表中 import_excel(table) for i in tables: print(i)

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.

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.

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 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.

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.

Running Python code in Notepad requires the Python executable and NppExec plug-in to be installed. After installing Python and adding PATH to it, configure the command "python" and the parameter "{CURRENT_DIRECTORY}{FILE_NAME}" in the NppExec plug-in to run Python code in Notepad through the shortcut key "F6".

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.
