Python mainly uses third-party module libraries xlrd, xlwt, xluntils, pyExcelerator and Pandas to process excel file data.
1, xlrd
xlrd is used to read and write data from Excel, but I usually only use it to read Operations and write operations will encounter some problems. It is more convenient to use xlrd to read. The process is the same as the usual manual operation of Excel. Open the workbook (Workbook), select the worksheet (sheets), and then operate the cell (cell).
import xlrd data = xlrd.open_workbook('text.xls','rb') print('工作表名为:'+ data.sheet_names()[0]) table = data.sheets()[0] nrows = table.nrows ncols = table.ncols print('表格行数为%d,列数为%d'%(nrows,ncols)) #输出每一行的值 for item in range(table.nrows): print(table.row_values(item)) #获取单元格的值 cell_A1 = table.row(0)[0].value cell_A2 = table.cell(0,0).value cell_A3 = table.col(0)[0].value print(cell_A1) print(cell_A2) print(cell_A3)
2, xlwt
If xlrd is not a simple Reader (if the last two characters in xlrd are regarded as Reader, then the last two characters of xlwt Similar to a Writer), then xlwt is a pure Writer, because it can only write to Excel. Not only do xlwt and xlrd have similar names, but many of their functions and operation formats are exactly the same. Below is a brief summary of common operations
import xlwt data = xlwt.Workbook() #新建工作表,可对同一个单元格重复操作 table = data.add_sheet('hello', cell_overwrite_ok=True) #写入数据到A1单元格 table.write(0,0,'hello world') #保存文件,不支持xlsx格式 data.save('test2.xls') #初始化样式 style = xlwt.XFStyle() #创建字体 font = xlwt.Font() #指定字体名字 font.name = 'Times New Roman' #字体加粗 font.bold = True #将该font设定为style的字体 style.font = font #写入到文件时使用该样式 table.write(0,1,'ni hao', style) #修改完要再一次保存 data.save('test2.xls')

Python is easier to learn and use, while C is more powerful but complex. 1. Python syntax is concise and suitable for beginners. Dynamic typing and automatic memory management make it easy to use, but may cause runtime errors. 2.C provides low-level control and advanced features, suitable for high-performance applications, but has a high learning threshold and requires manual memory and type safety management.

Python and C have significant differences in memory management and control. 1. Python uses automatic memory management, based on reference counting and garbage collection, simplifying the work of programmers. 2.C requires manual management of memory, providing more control but increasing complexity and error risk. Which language to choose should be based on project requirements and team technology stack.

Python's applications in scientific computing include data analysis, machine learning, numerical simulation and visualization. 1.Numpy provides efficient multi-dimensional arrays and mathematical functions. 2. SciPy extends Numpy functionality and provides optimization and linear algebra tools. 3. Pandas is used for data processing and analysis. 4.Matplotlib is used to generate various graphs and visual results.

Whether to choose Python or C depends on project requirements: 1) Python is suitable for rapid development, data science, and scripting because of its concise syntax and rich libraries; 2) C is suitable for scenarios that require high performance and underlying control, such as system programming and game development, because of its compilation and manual memory management.

Python is widely used in data science and machine learning, mainly relying on its simplicity and a powerful library ecosystem. 1) Pandas is used for data processing and analysis, 2) Numpy provides efficient numerical calculations, and 3) Scikit-learn is used for machine learning model construction and optimization, these libraries make Python an ideal tool for data science and machine learning.

Is it enough to learn Python for two hours a day? It depends on your goals and learning methods. 1) Develop a clear learning plan, 2) Select appropriate learning resources and methods, 3) Practice and review and consolidate hands-on practice and review and consolidate, and you can gradually master the basic knowledge and advanced functions of Python during this period.

Key applications of Python in web development include the use of Django and Flask frameworks, API development, data analysis and visualization, machine learning and AI, and performance optimization. 1. Django and Flask framework: Django is suitable for rapid development of complex applications, and Flask is suitable for small or highly customized projects. 2. API development: Use Flask or DjangoRESTFramework to build RESTfulAPI. 3. Data analysis and visualization: Use Python to process data and display it through the web interface. 4. Machine Learning and AI: Python is used to build intelligent web applications. 5. Performance optimization: optimized through asynchronous programming, caching and code

Python is better than C in development efficiency, but C is higher in execution performance. 1. Python's concise syntax and rich libraries improve development efficiency. 2.C's compilation-type characteristics and hardware control improve execution performance. When making a choice, you need to weigh the development speed and execution efficiency based on project needs.

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
