Question

我需要将多个字典写入json，然后将其读回。我怎样才能做到这一点？我使用的代码将字典写到文件中，但我无法读取它们。

if "__main__" == __name__:
    s = 0
    if s == 0:
        for i in range(2):
            test = dict()
            test["test_1"] = i
            test["test_2"] = i+1
            f = open('test.txt', 'a')
            f.write(json.dumps(test))
    else:
        f = open('test.txt', 'r')
        test = json.loads(f.read())
        print(test)

阅读时出错：

test = json.loads(f.read())
  File "/usr/lib/python3.6/json/__init__.py", line 354, in loads
    return _default_decoder.decode(s)
  File "/usr/lib/python3.6/json/decoder.py", line 342, in decode
    raise JSONDecodeError("Extra data", s, end)
json.decoder.JSONDecodeError: Extra data: line 1 column 27 (char 26)

一个json文件中不能有多个词典（或多个对象）。但是您可以有一个列表：

REM This adds the folder containing php.exe to the path
PATH=%PATH%;C:\php


REM Change Directory to the folder containing your script
CD C:\Apache24\htdocs\phpspreadsheet\reporting

REM Execute
php report_v1.1.php


REM Change Directory to the folder containing your script
CD C:\Apache24\htdocs\Automation

REM Execute
php report.php

如何将多个字典写入json / txt文件并读回？
