8 个 Python 实用脚本，收藏备用
发布时间：2025-11-05 07:26:37 来源：创站工坊 作者：IT科技
脚本写的收藏备用好，下班下得早!程序员的用脚日常工作除了编写程序代码，还不可避免地需要处理相关的收藏备用测试和验证工作。
例如，用脚访问某个网站一直不通，收藏备用需要确定此地址是用脚否可访问，服务器返回什么，收藏备用进而确定问题在于什么。用脚完成这个任务，收藏备用如果一味希望采用编译型语言来编写这样的用脚代码，实践中的收藏备用时间和精力是不够的，这个时候就需要发挥脚本的用脚神奇作用!
好不夸张的说，能否写出高效实用的收藏备用脚本代码，直接影响着一个程序员的用脚幸福生活[下班时间]。下面整理 8 个实用的免费源码下载收藏备用 Python 脚本，需要的时候改改直接用，建议收藏!
1.解决 linux 下 unzip 乱码的问题。
import os import sys import zipfile import argparse s = \\x1b[%d;%dm%s\\x1b[0m def unzip(path): file = zipfile.ZipFile(path,"r") if args.secret: file.setpassword(args.secret) for name in file.namelist(): try: utf8name=name.decode(gbk) pathname = os.path.dirname(utf8name) except: utf8name=name pathname = os.path.dirname(utf8name) #print s % (1, 92, >> extracting:), utf8name #pathname = os.path.dirname(utf8name) if not os.path.exists(pathname) and pathname != "": os.makedirs(pathname) data = file.read(name) if not os.path.exists(utf8name): try: fo = open(utf8name, "w") fo.write(data) fo.close except: pass file.close() def main(argv): ###################################################### # for argparse p = argparse.ArgumentParser(description=解决unzip乱码) p.add_argument(xxx, type=str, nargs=*, \ help=命令对象.) p.add_argument(-s, --secret, action=store, \ default=None, help=密码) global args args = p.parse_args(argv[1:]) xxx = args.xxx for path in xxx: if path.endswith(.zip): if os.path.exists(path): print s % (1, 97, ++ unzip:), path unzip(path) else: print s % (1, 91, !! file doesn\t exist.), path else: print s % (1, 91, !! file isn\t a zip file.), path if __name__ == __main__: argv = sys.argv main(argv)2.统计当前根目录代码行数。
# coding=utf-8 import os import time # 设定根目录 basedir = ./ filelists = [] # 指定想要统计的文件类型 whitelist = [cpp, h] #遍历文件, 递归遍历文件夹中的所有 def getFile(basedir): global filelists for parent,dirnames,filenames in os.walk(basedir): for filename in filenames: ext = filename.split(.)[-1] #只统计指定的文件类型，略过一些log和cache文件 if ext in whitelist: filelists.append(os.path.join(parent,filename)) #统计一个的行数 def countLine(fname): count = 0 # 把文件做二进制看待,read. for file_line in open(fname, rb).readlines(): if file_line != and file_line != \n: #过滤掉空行 count += 1 print (fname + ---- , count) return count if __name__ == __main__ : startTime = time.clock() getFile(basedir) totalline = 0 for filelist in filelists: totalline = totalline + countLine(filelist) print (total lines:,totalline) print (Done! Cost Time: %0.2f second % (time.clock() - startTime))3.扫描当前目录和所有子目录并显示大小。
import os import sys try: directory = sys.argv[1] except IndexError: sys.exit("Must provide an argument.") dir_size = 0 fsizedicr = {Bytes: 1, Kilobytes: float(1) / 1024, Megabytes: float(1) / (1024 * 1024), Gigabytes: float(1) / (1024 * 1024 * 1024)} for (path, dirs, files) in os.walk(directory): for file in files: filename = os.path.join(path, file) dir_size += os.path.getsize(filename) fsizeList = [str(round(fsizedicr[key] * dir_size, 2)) + " " + key for key in fsizedicr] if dir_size == 0: print ("File Empty") else: for units in sorted(fsizeList)[::-1]: print ("Folder Size: " + units)4.将源目录240天以上的所有文件移动到目标目录。
import shutil import sys import time import os import argparse usage = python move_files_over_x_days.py -src [SRC] -dst [DST] -days [DAYS] description = Move files from src to dst if they are older than a certain number of days. Default is 240 days args_parser = argparse.ArgumentParser(usage=usage, description=description) args_parser.add_argument(-src, --src, type=str, nargs=?, default=., help=(OPTIONAL) Directory where files will be moved from. Defaults to current directory) args_parser.add_argument(-dst, --dst, type=str, nargs=?, required=True, help=(REQUIRED) Directory where files will be moved to.) args_parser.add_argument(-days, --days, type=int, nargs=?, default=240, help=(OPTIONAL) Days value specifies the minimum age of files to be moved. Default is 240.) args = args_parser.parse_args() if args.days < 0: args.days = 0 src = args.src # 设置源目录 dst = args.dst # 设置目标目录 days = args.days # 设置天数 now = time.time() # 获得当前时间 if not os.path.exists(dst): os.mkdir(dst) for f in os.listdir(src): # 遍历源目录所有文件 if os.stat(f).st_mtime < now - days * 86400: # 判断是否超过240天 if os.path.isfile(f): # 检查是否是文件 shutil.move(f, dst) # 移动文件5.扫描脚本目录，并给出不同类型脚本的计数。
import os import shutil from time import strftime logsdir="c:\logs\puttylogs" zipdir="c:\logs\puttylogs\zipped_logs" zip_program="zip.exe" for files in os.listdir(logsdir): if files.endswith(".log"): files1=files+"."+strftime("%Y-%m-%d")+".zip" os.chdir(logsdir) os.system(zip_program + " " + files1 +" "+ files) shutil.move(files1, zipdir) os.remove(files)6.下载Leetcode的算法题。
