如何为文件创建哈希库并放入字典

Question

我在一个文件夹中有 4 个文件 hash.py size_1.py size_2.py size.py。 size_1.py , size_2.py 大小相同。

我正在为文件创建 hashlib

import hashlib, os, sys
result = {}
for root, dirs,files in os.walk(".", topdown=True):
    for name in files:
        #print(os.path.join(root, name))
        FileName = (os.path.join(root, name))

        hasher = hashlib.md5()
        with open(str(FileName), 'rb') as afile:
            buf = afile.read()
            hasher.update(buf)
        file_hash = (afile,hasher.hexdigest())
        #print (file_hash)
        result[file_hash[1]] = file_hash[0]
        #if file_hash[1] in result:
        #    result[file_hash[1]].append(file_hash[0])
        #else:
        #    result[file_hash[1]] = file_hash[0]

print (result)

我的输出

{'e12d780eba6e03a7c1cafa394ef9f31f': <_io.BufferedReader name='./size.py'>, '49eb7137273ec333727ea0f5279fe040': <_io.BufferedReader name='./size_1.py'>, '35e93b380f084d5187976beae746492e': <_io.BufferedReader name='./hash.py'>}

我想要的

{'e12d780eba6e03a7c1cafa394ef9f31f': ['./size.py']>, '49eb7137273ec333727ea0f5279fe040': ['./size_1.py','./size_1.py'], '35e93b380f084d5187976beae746492e': ['./hash.py']}

此处必须进行 2 次提升

删除 <_io.BufferedReader 名称=
用字典的形式写出来

Answer 1

我不确定你为什么要在不需要的地方创建元组。

import hashlib, os, sys

result = {}
for root, dirs, files in os.walk('.', topdown=True):
    for name in files:
        hasher = hashlib.md5()
        fn = os.path.join(root, name)
        with open(fn, 'rb') as afile:
            buf = afile.read()
            hasher.update(buf)
            file_hash = hasher.hexdigest()
        if fn in result:
            result[fn].append(file_hash)
        else:
            result[fn] = [file_hash]

感谢@olvin

import hashlib, os, sys

result = {}
for root, dirs, files in os.walk('.', topdown=True):
    for name in files:
        hasher = hashlib.md5()
        fn = os.path.join(root, name)
        with open(fn, 'rb') as afile:
            buf = afile.read()
            hasher.update(buf)
            file_hash = hasher.hexdigest()
        if file_hash in result:
            result[file_hash].append(fn)
        else:
            result[file_hash] = [fn]
print (result)
