直接输入下载地址就行了，但不能下载txt、bat等文本形式，会出现乱码的情况。

#!/usr/bin/env pythonimport urllib2import sys,osdef main(url):    ext = url[url.rindex("."):]    filename = url[url.rindex("/")+1:url.rindex(".")]    folder = os.getcwd()    try:        f = urllib2.urlopen(url)        with open(filename+ext,"wb") as code:            code.write(f.read())    except:        print("parameter error!the url is error?")        sys.exit(0)    print("download OK,you can find it in %s\\" %folder)if __name__ == "__main__":    if len(sys.argv) < 2:        print("\n\targument error!\n")	print("\tUseage: file_download.py https://www.xxoo/hehe.zip")    else:        main(sys.argv[1])

　求乱码解决方案啊！！
