Как sys.stdin, который выглядит как словарь превратить в словарь?

Question

[Denis]

sys.stdin выглядит так:
{'Action': ['Terminal Velocity;1994', 'Terminator 2: Judgment Day;1991', 'Terminator, The;1984', 'Terminator 3: Rise of the Machines;2003', 'Terminator Salvation;2009', 'Terminator Genisys;2015'], 'Mystery': ['Terminal Velocity;1994'], 'Thriller': ['Terminal Velocity;1994', 'Terminator, The;1984', 'Terminator Salvation;2009', 'Terminator Genisys;2015'], 'Sci-Fi': ['Terminator 2: Judgment Day;1991', 'Terminator, The;1984', 'Terminator 3: Rise of the Machines;2003', 'Terminator Salvation;2009', 'Terminator Genisys;2015'], 'Adventure': ['Terminator 3: Rise of the Machines;2003', 'Terminator Salvation;2009', 'Terminator Genisys;2015'], 'Comedy': ['Terminal, The;2004'], 'Drama': ['Terminal, The;2004'], 'Romance': ['Terminal, The;2004']}

мне нужно дальше использовать этот словарь
как мне его превратить в переменную с типом dict?
вот мой код

# sort.py 

import sys
import json

def dict_sorted_by_genre(dict_data):
    # sort genres by alphabetically
    sorted_result = sorted(dict_data.items(), key=lambda x: x[0])
    dict_result = dict(sorted_result)
    return dict_result


if __name__ == "__main__":
    dict = json.loads(str(sys.stdin))
    sorted_dict = dict_sorted_by_genre(dict)
    print(sorted_dict)

это запуск команды:
denislysenko@MacBook-Pro-Denis homework5 % cat files/movies.csv | python3 mapper.py -regexp Termi | python3 shuffle.py | python3 sort.py

выскакивает вот такая ошибка:
Traceback (most recent call last):
File "/Users/denislysenko/Desktop/Intern/coherent-training-denis-lysenko/homework5/sort.py", line 12, in
dict = json.loads(str(sys.stdin))

непонятно что у тебя шаффл передает в пайп...

[Denis]

шафл печатет в консоль

{'Action': ['Terminal Velocity;1994', 'Terminator 2: Judgment Day;1991', 'Terminator, The;1984', 'Terminator 3: Rise of the Machines;2003', 'Terminator Salvation;2009', 'Terminator Genisys;2015'], 'Mystery': ['Terminal Velocity;1994'], 'Thriller': ['Terminal Velocity;1994', 'Terminator, The;1984', 'Terminator Salvation;2009', 'Terminator Genisys;2015'], 'Sci-Fi': ['Terminator 2: Judgment Day;1991', 'Terminator, The;1984', 'Terminator 3: Rise of the Machines;2003', 'Terminator Salvation;2009', 'Terminator Genisys;2015'], 'Adventure': ['Terminator 3: Rise of the Machines;2003', 'Terminator Salvation;2009', 'Terminator Genisys;2015'], 'Comedy': ['Terminal, The;2004'], 'Drama': ['Terminal, The;2004'], 'Romance': ['Terminal, The;2004']}

Prog, вот код shuffle.py

import sys


def shuffle(data):
    result = {} # result is a dict where key = genre, value = list with many 'film_title;year'
    for line in data:
        key, value = line.split("\t")

        key = key[:-1]
        value = value[1:-1]

        if key not in result:
            result[key] = []
            result[key].append(value)
        elif key in result:
            result[key].append(value)

    return result

if __name__ == "__main__":
    print(shuffle(sys.stdin))

Ты пробовал вывести str(sys.stdin) на экран?

>>> str(sys.stdin)
"<_io.TextIOWrapper name='<stdin>' mode='r' encoding='utf-8'>"

sys.stdin - это файл, открытый в текстовом режиме. Работай с ним как с файлом.

вот что выводит:
<_io.TextIOWrapper name='' mode='r' encoding='utf-8'>
Exception ignored in: <_io.TextIOWrapper name='' mode='w' encoding='utf-8'>
BrokenPipeError: [Errno 32] Broken pipe

но shuffle.py выводит в консоль:
{'Action': ['Terminal Velocity;1994', 'Terminator 2: Judgment Day;1991', 'Terminator, The;1984', 'Terminator 3: Rise of the Machines;2003', 'Terminator Salvation;2009', 'Terminator Genisys;2015'], 'Mystery': ['Terminal Velocity;1994'], 'Thriller': ['Terminal Velocity;1994', 'Terminator, The;1984', 'Terminator Salvation;2009', 'Terminator Genisys;2015'], 'Sci-Fi': ['Terminator 2: Judgment Day;1991', 'Terminator, The;1984', 'Terminator 3: Rise of the Machines;2003', 'Terminator Salvation;2009', 'Terminator Genisys;2015'], 'Adventure': ['Terminator 3: Rise of the Machines;2003', 'Terminator Salvation;2009', 'Terminator Genisys;2015'], 'Comedy': ['Terminal, The;2004'], 'Drama': ['Terminal, The;2004'], 'Romance': ['Terminal, The;2004']}

Так делать нельзя:
dict = json.loads(str(sys.stdin))
Нужно либо так:
dict = json.load(sys.stdin)
либо так:
dict = json.loads(sys.stdin.read())
Приведите остальной код тоже. Там наверняка такие же ошибки.
