所以就想把这些照片翻着看一遍,可是拷出来的照片手机
里是按时间自动分文件夹的,一个一个文件夹拷很是麻烦,于是打算写个python小脚本来完成这个工作(扯这么多,终于
到主题了,囧)
废话少说,上代码:
代码如下:
# -*- coding: utf-8 -*-
#!/usr/bin/python
#Filename:copyfile.py
import os,shutil
def mycopy(srcpath,dstpath):
if not os.path.exists(srcpath):
print "srcpath not exist!"
if not os.path.exists(dstpath):
print "dstpath not exist!"
for root,dirs,files in os.walk(srcpath,True):
for eachfile in files:
shutil.copy(os.path.join(root,eachfile),dstpath)
srcpath='e:\\pic'
dstpath='f:\\pictotal'
mycopy(srcpath,dstpath)
运行这个脚本,去f盘看看:
代码没有什么难懂的,主要是os.walk()函数,这个函数返回指定路径的三元组(起始路径,起始路径下的目录,起始路径下不带路径名的文件名列表)
它直接可以递归遍历到指定目录下的所有目录及文件名,比较好用。
也可以用os.listdir(dirname):函数来实现,listdir函数列出dirname下的目录和文件,然后通过一个判断:若是文件,则拷贝;若是目录,则继续递归
遍历,显然没有walk()函数用起来方便。不过不知道walk()函数内部是怎么实现的,若是直接将根目录下的所有文件存在list中性能上可能不太好,
后面可以用listdir()对比测一下。
可以看出,python仅需短短几行的代码就完成了这个工作,还是很方便的。若用C++来实现代码就比这个长了。
可见,语言无所谓高低,能高效方便实现目标就好,不是吗?

This tutorial demonstrates how to use Python to process the statistical concept of Zipf's law and demonstrates the efficiency of Python's reading and sorting large text files when processing the law. You may be wondering what the term Zipf distribution means. To understand this term, we first need to define Zipf's law. Don't worry, I'll try to simplify the instructions. Zipf's Law Zipf's law simply means: in a large natural language corpus, the most frequently occurring words appear about twice as frequently as the second frequent words, three times as the third frequent words, four times as the fourth frequent words, and so on. Let's look at an example. If you look at the Brown corpus in American English, you will notice that the most frequent word is "th

This article explains how to use Beautiful Soup, a Python library, to parse HTML. It details common methods like find(), find_all(), select(), and get_text() for data extraction, handling of diverse HTML structures and errors, and alternatives (Sel

Python's statistics module provides powerful data statistical analysis capabilities to help us quickly understand the overall characteristics of data, such as biostatistics and business analysis. Instead of looking at data points one by one, just look at statistics such as mean or variance to discover trends and features in the original data that may be ignored, and compare large datasets more easily and effectively. This tutorial will explain how to calculate the mean and measure the degree of dispersion of the dataset. Unless otherwise stated, all functions in this module support the calculation of the mean() function instead of simply summing the average. Floating point numbers can also be used. import random import statistics from fracti

Serialization and deserialization of Python objects are key aspects of any non-trivial program. If you save something to a Python file, you do object serialization and deserialization if you read the configuration file, or if you respond to an HTTP request. In a sense, serialization and deserialization are the most boring things in the world. Who cares about all these formats and protocols? You want to persist or stream some Python objects and retrieve them in full at a later time. This is a great way to see the world on a conceptual level. However, on a practical level, the serialization scheme, format or protocol you choose may determine the speed, security, freedom of maintenance status, and other aspects of the program
