从Python子流程调用获取控制台输出，并将其转换为有效的CSV（和/或JSON）

我处理的是大串数字，你可以在这里看到：

它们是这样处理的

echo "INPUT_DATA" >> file_name && evm disasm file_name

输出数据如下所示：

000000: PUSH1 0x60
000002: PUSH1 0x40
000004: MSTORE
000005: CALLDATASIZE
000006: ISZERO
000007: PUSH2 0x006c
000010: JUMPI
000011: PUSH1 0xe0
000013: PUSH1 0x02
000015: EXP
000016: PUSH1 0x00
000018: CALLDATALOAD
000019: DIV

PUSH1 0x60, PUSH1 0x40, MSTORE, CALLDATASIZE, ISZERO, PUSH2 0x006c, JUMPI, PUSH1 0xe0, PUSH1 0x02, EXP, PUSH1 0x00, CALLDATALOAD, DIV

我最终想做的是将输出呈现为CSV（或者也可以是JSON）。大概是这样的：

000000: PUSH1 0x60
000002: PUSH1 0x40
000004: MSTORE
000005: CALLDATASIZE
000006: ISZERO
000007: PUSH2 0x006c
000010: JUMPI
000011: PUSH1 0xe0
000013: PUSH1 0x02
000015: EXP
000016: PUSH1 0x00
000018: CALLDATALOAD
000019: DIV

PUSH1 0x60, PUSH1 0x40, MSTORE, CALLDATASIZE, ISZERO, PUSH2 0x006c, JUMPI, PUSH1 0xe0, PUSH1 0x02, EXP, PUSH1 0x00, CALLDATALOAD, DIV

但是，目前我只将其记录到控制台，使用以下脚本：

import sys
import subprocess

def my_test_func(filename, data):
    with open(filename, 'w') as fd:
        fd.write(data)
        fd.write('\n')
    return subprocess.check_output(['evm', 'disasm', filename])




if '__main__' == __name__:

    file_name = sys.argv[1] 
    byte_code = sys.argv[2]
    status = my_test_func(file_name, byte_code)

    # python opcode-farmer.py 'tst2' '6005600401'
    print(status)

^该脚本有点整洁，因为正如您所看到的，它在Python脚本中创建了一个子进程

我想知道的是——获取输出的最佳方式是什么，而不仅仅是在控制台中编写输出——将其放入一个可以将其转换为CSV的过程中。所以-我当然有一些关于如何做到这一点的想法-但是-几乎没有失败-我的想法往往是计算最昂贵和最不雅观的可能方式-所以我想看看So社区提出了什么样的建议

这类作品：

edits = csv.reader(status.splitlines(), delimiter=",")
for row in edits:
    print(row)

但是，也不是真的，它提供了以下输出：

['6005600401']
['000000: PUSH1 0x05']
['000002: PUSH1 0x04']
['000004: ADD']

这在两个方面都是次优的——首先——许多类似的列表或口述很难在以后处理——而且——它不会去除所有多余的信息。我需要用正则表达式吗

我真正想要的是：

PUSH1 0x60, PUSH1 0x40, MSTORE, CALLDATASIZE, ISZERO, PUSH2 0x006c, JUMPI, PUSH1 0xe0, PUSH1 0x02, EXP, PUSH1 0x00, CALLDATALOAD, DIV

这个怎么样

', '.join([' '.join(line.split()[1:]) for line in status.splitlines()])

---

那么，这在哪里合适呢？我已经编程好几个小时了，现在我有点-看不清楚如何集成该组件
