python 将字符串写入文件给出空文件

Question

I try to write a string to a file in Python and fail,

mystr = '{"a": "{\'a\': [\'b\': [\'\\saaaalam\\Mira.h\']}, {\'c\': [\'C:\\a\\t.exe\']}", "b": "open"}'

with open('test.json', 'w') as out_file:
   out_file.write(mystr)

The file "test.json" does not exist, However. if I for example remove an "a" in "saaalam" it works.

Your code is working. You should check if python process has the right to create that file in your OS. In Linux and MacOS you can provide yourself access to write in the current directory with:

chmod 744 .

Another option is you are looking for your file at the wrong place. You should check the working directory in your IDE or try to run the script from the console.
