#login(user='anonymous',passwd='', acct='') 登录到FTP服务器,所有的参数都是可选的
#pwd() 得到当前工作目录
#cwd(path) 把当前工作目录设置为path
#dir([path[,...[,cb]]) 显示path目录里的内容,可选的参数cb 是一个回调函数,它会被传给retrlines()方法
#nlst([path[,...]) 与dir()类似,但返回一个文件名的列表,而不是显示这些文件名
#retrlines(cmd [, cb]) 给定FTP 命令(如“RETR filename”),用于下载文本文件。可选的回调函数cb 用于处理文件的每一行
#retrbinary(cmd, cb[,bs=8192[, ra]]) 与retrlines()类似,只是这个指令处理二进制文件。回调函数cb 用于处理每一块(块大小默认为8K)下载的数据。
#storlines(cmd, f) 给定FTP 命令(如“STOR filename”),以上传文本文件。要给定一个文件对象f
#storbinary(cmd, f[,bs=8192]) 与storlines()类似,只是这个指令处理二进制文件。要给定一个文件对象f,上传块大小bs 默认为8Kbs=8192])
#rename(old, new) 把远程文件old 改名为new
#delete(path) 删除位于path 的远程文件
#mkd(directory) 创建远程目录
#每个需要输入的地方,需要进行排查检错。仅仅这个功能太小了。不过根据实际情况更改,放在bt里边当个小工具即可
#有点烂,没有做任何try

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

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

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
