python与excel结合的方法:首先获取工作表的方法和属性,并创建或删除工作表;然后定位单元格并访问;最后使用函数【copy_worksheet】拷贝工作表即可。
python与excel结合的方法:
step1 使用load_workbook(r’xlsx文件路径‘)
>>> import openpyxl >>> wb = openpyxl.load_workbook(r'D:\PycharmProjects\requests\250.xlsx') >>> type(wb) <class 'openpyxl.workbook.workbook.Workbook'>

step2 获取工作表的方法和属性
get_sheet_names()或者sheetnames
>>> wb.get_sheet_names() ['Sheet'] >>> wb.sheetnames ['Sheet'] >>> ws = wb.get_sheet_by_name('Sheet') # 工作表对象
step3 创建和删除工作表
create_sheet 创建工作表
remove_sheet 删除工作表(删除工作表的对象)
>>> rnx = wb.create_sheet(index = 0,title = 'sheet1') >>> wb.get_sheet_names() ['sheet1', 'Sheet'] # 注意删除工作表时,要删除工作表的对象 ws = wb.get_sheet_by_name('工作表') >>> wb.remove_sheet(wb.get_sheet_by_name('sheet1')) >>> wb.sheetnames ['Sheet']
step4 定位单元格
row 行
column 列
coordinate 坐标
offset 偏移 offset(行偏移,列偏移)
>>> c = ws['A2'] >>> c.row 2 >>> c.column 'A' >>> c.coordinate 'A2' >>> d = c.offset(2,0) >>> d.value '这个杀手不太冷'
step5 ’AA‘是多少
openpyxl.cell.cell.get_column_letter()
openpyxl.cell.cell.column_index_from_string()
>>> openpyxl.cell.cell.get_column_letter(27) 'AA' >>> openpyxl.cell.cell.column_index_from_string('AA') 27
step6 访问多个单元格
先迭代行再去迭代列
>>> for each_movies in ws['A2':'B10']: # each_movies是一个元祖 for each_cell in each_movies: print(each_cell.value,end = ' ') print('\n') 肖申克的救赎 9.6 霸王别姬 9.6 这个杀手不太冷 9.4 阿甘正传 9.4 美丽人生 9.5 泰坦尼克号 9.3 千与千寻 9.3 辛德勒的名单 9.5 盗梦空间 9.3
>>> for each_rows in ws.rows: print(each_rows[1].value) 评分 9.6 9.6 9.4 9.4 .... 8.6
还可以指定迭代多少个
>>> for each_row in ws.iter_rows(min_row = 2,min_col = 1,max_row = 4,max_col = 2): print(each_row[0].value) 肖申克的救赎 霸王别姬 这个杀手不太冷
step7 拷贝工作表
copy_worksheet(工作表)
>>> new = wb.copy_worksheet(ws) >>> type(new) <class 'openpyxl.worksheet.worksheet.Worksheet'> >>> wb.save(r'D:\PycharmProjects\requests\250.xlsx') #注意先把原先打开的excel文件关闭再去运行代码

Python and C each have their own advantages, and the choice should be based on project requirements. 1) Python is suitable for rapid development and data processing due to its concise syntax and dynamic typing. 2)C is suitable for high performance and system programming due to its static typing and manual memory management.

Choosing Python or C depends on project requirements: 1) If you need rapid development, data processing and prototype design, choose Python; 2) If you need high performance, low latency and close hardware control, choose C.

By investing 2 hours of Python learning every day, you can effectively improve your programming skills. 1. Learn new knowledge: read documents or watch tutorials. 2. Practice: Write code and complete exercises. 3. Review: Consolidate the content you have learned. 4. Project practice: Apply what you have learned in actual projects. Such a structured learning plan can help you systematically master Python and achieve career goals.

Methods to learn Python efficiently within two hours include: 1. Review the basic knowledge and ensure that you are familiar with Python installation and basic syntax; 2. Understand the core concepts of Python, such as variables, lists, functions, etc.; 3. Master basic and advanced usage by using examples; 4. Learn common errors and debugging techniques; 5. Apply performance optimization and best practices, such as using list comprehensions and following the PEP8 style guide.

Python is suitable for beginners and data science, and C is suitable for system programming and game development. 1. Python is simple and easy to use, suitable for data science and web development. 2.C provides high performance and control, suitable for game development and system programming. The choice should be based on project needs and personal interests.

Python is more suitable for data science and rapid development, while C is more suitable for high performance and system programming. 1. Python syntax is concise and easy to learn, suitable for data processing and scientific computing. 2.C has complex syntax but excellent performance and is often used in game development and system programming.

It is feasible to invest two hours a day to learn Python. 1. Learn new knowledge: Learn new concepts in one hour, such as lists and dictionaries. 2. Practice and exercises: Use one hour to perform programming exercises, such as writing small programs. Through reasonable planning and perseverance, you can master the core concepts of Python in a short time.

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.
