输出	主要语法
ext	`os.path.normcase(os.path.splitext[1])`
files	`os.path.isfile`
bytes	以二进制(`rb`)读文件，`len`的输出
lines	`str(data, 'latin-1').splitlines()`
words	`len(data.split())`的输出
binary	`if b'\0' in data`
dirs	os.path.isdir
lnk	os.path.islink

checkpip.py

1 2	The latest version of setuptools on PyPI is 46.2.0, but ensurepip has 40.8.0 The latest version of pip on PyPI is 20.1, but ensurepip has 19.0.3

# 主要是检查版本
import ensurepip

print(ensurepip._PROJECTS)
# [('setuptools', '40.8.0'), ('pip', '19.0.3')]

checkpyc.py

检查pyc文件是否最新

import importlib.util

print(importlib.util.MAGIC_NUMBER)
# b'B\r\r\n'

cleanfuture.py

修改py文件的future语法

import sys

def errprint(*args):
    strings = map(str, args)
    msg = ' '.join(strings)
    if msg[-1:] != '\n':
        msg += '\n'
    sys.stderr.write(msg)
    
errprint("Usage:", __doc__)
