python高手之路python处理excel文件(方法汇总)
用python来自动生成excel数据文件。python处理excel文件主要是第三方模块库xlrd、xlwt、xluntils和pyExcelerator,除此之外,python处理excel还可以用win32com和openpyxl模块。
方法一:
小罗问我怎么从excel中读取数据,然后我百了一番,做下记录
excel数据图(小罗说数据要给客户保密,我随手写了几行数据):
python读取excel文件代码:
#!/usr/bin/env python # -*- coding: utf-8 -*- # 读取excel数据 # 小罗的需求,取第二行以下的数据,然后取每行前13列的数据 import xlrd data = xlrd.open_workbook('test.xls') # 打开xls文件 table = data.sheets()[0] # 打开第一张表 nrows = table.nrows # 获取表的行数 for i in range(nrows): # 循环逐行打印 if i == 0: # 跳过第一行 continue print table.row_values(i)[:13] # 取前十三列
excel的写操作等后面用到的时候在做记录
方法二:
使用xlrd读取文件,使用xlwt生成Excel文件(可以控制Excel中单元格的格式)。但是用xlrd读取excel是不能对其进行操作的;而xlwt生成excel文件是不能在已有的excel文件基础上进行修改的,如需要修改文件就要使用xluntils模块。pyExcelerator模块与xlwt类似,也可以用来生成excel文件。

Python is suitable for data science, web development and automation tasks, while C is suitable for system programming, game development and embedded systems. Python is known for its simplicity and powerful ecosystem, while C is known for its high performance and underlying control capabilities.

You can learn basic programming concepts and skills of Python within 2 hours. 1. Learn variables and data types, 2. Master control flow (conditional statements and loops), 3. Understand the definition and use of functions, 4. Quickly get started with Python programming through simple examples and code snippets.

Python excels in gaming and GUI development. 1) Game development uses Pygame, providing drawing, audio and other functions, which are suitable for creating 2D games. 2) GUI development can choose Tkinter or PyQt. Tkinter is simple and easy to use, PyQt has rich functions and is suitable for professional development.

You can learn the basics of Python within two hours. 1. Learn variables and data types, 2. Master control structures such as if statements and loops, 3. Understand the definition and use of functions. These will help you start writing simple Python programs.

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.

To maximize the efficiency of learning Python in a limited time, you can use Python's datetime, time, and schedule modules. 1. The datetime module is used to record and plan learning time. 2. The time module helps to set study and rest time. 3. The schedule module automatically arranges weekly learning tasks.

Python is widely used in the fields of web development, data science, machine learning, automation and scripting. 1) In web development, Django and Flask frameworks simplify the development process. 2) In the fields of data science and machine learning, NumPy, Pandas, Scikit-learn and TensorFlow libraries provide strong support. 3) In terms of automation and scripting, Python is suitable for tasks such as automated testing and system management.

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.
