下面是最终代码 (windows下实现的)
# -*- coding: cp936 -*-
import os
path = 'D:\\图片\\'
for file in os.listdir(path):
if os.path.isfile(os.path.join(path,file))==True:
if file.find('.')newname=file+'rsfdjndk.jpg'
os.rename(os.path.join(path,file),os.path.join(path,newname))
print file,'ok'
# print file.split('.')[-1]
实现的方法是:首先遍历path指定的目录,如果是文件(不是文件夹)并且文件名中不存在 ‘.' ,也就是没有后缀名,就把这个文件加上后缀名,然后重命名
有些细节需要注意:
1.如果path指定的文件夹不是这个程序的所在的目录,rename函数里面的路径就必须是绝对路径,否则就会报‘WindowsError: [Error 2]'错误
2.重命名时如果新文件名已经存在,就会报‘WindowsError: [Error 183]' 错误,所以,新文件名最好加上一些随机字符串
3.如果改文件名或者后缀名可以用split() 函数进行分割
4.find函数如果找不到指定的字符串的话就会返回 ‘-1'

Python's flexibility is reflected in multi-paradigm support and dynamic type systems, while ease of use comes from a simple syntax and rich standard library. 1. Flexibility: Supports object-oriented, functional and procedural programming, and dynamic type systems improve development efficiency. 2. Ease of use: The grammar is close to natural language, the standard library covers a wide range of functions, and simplifies the development process.

Python is highly favored for its simplicity and power, suitable for all needs from beginners to advanced developers. Its versatility is reflected in: 1) Easy to learn and use, simple syntax; 2) Rich libraries and frameworks, such as NumPy, Pandas, etc.; 3) Cross-platform support, which can be run on a variety of operating systems; 4) Suitable for scripting and automation tasks to improve work efficiency.

Yes, learn Python in two hours a day. 1. Develop a reasonable study plan, 2. Select the right learning resources, 3. Consolidate the knowledge learned through practice. These steps can help you master Python in a short time.

Python is suitable for rapid development and data processing, while C is suitable for high performance and underlying control. 1) Python is easy to use, with concise syntax, and is suitable for data science and web development. 2) C has high performance and accurate control, and is often used in gaming and system programming.

The time required to learn Python varies from person to person, mainly influenced by previous programming experience, learning motivation, learning resources and methods, and learning rhythm. Set realistic learning goals and learn best through practical projects.

Python excels in automation, scripting, and task management. 1) Automation: File backup is realized through standard libraries such as os and shutil. 2) Script writing: Use the psutil library to monitor system resources. 3) Task management: Use the schedule library to schedule tasks. Python's ease of use and rich library support makes it the preferred tool in these areas.

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 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.
