  大佬，帮你加了个缩进

  #/bin/python
  #coding=utf8
  
  import os,sys
  
  def choiceversion(version):
      if version == '2.7':
          url = "https://www.python.org/ftp/python/2.7.16/Python-2.7.16.tgz"
          download(url)
      elif version == '3.5':
          url = "https://www.python.org/ftp/python/2.7.16/Python-3.5.2.tgz"
          download(url)
      else:
          print("输入的版本号有误，请输入'2.7'或者'3.5'")
          install(version)
  
  def download(url):
      try:
          cmd = "wget "+url
          os.system(cmd)
      except:
          print("下载源码包失败，请检查当前网络")
          sys.exit(1)
  
  def install(version):
      if version == 2.7:

  version_string = str(version_float)
  
  choiceversion(version_string)
