打开文件时，就像看不到文件，FileNotFoundError: [Errno 2] No such file or directory: 'setting.json'

问题遇到的现象和发生背景

编写字符画，想打开一个设置的json文件。文件有了，用open()打开时它说没有该文件。

问题相关代码，请勿粘贴截图

from PIL import Image
import json


class Img(Image.Image):
    def __init__(self, img: Image.Image):
        self.img = img.convert('L')

    def get_img(self):
        return self.img

    @staticmethod
    def getchar(gray, ls=list('W#C)|^. ')):
        print(len(ls))
        if 65536 % len(ls) != 0:
            raise ValueError('Input data must divide 65536 (that is, a multiple of 4)')
        return ls[int(gray // (256 // len(ls)))]


class write_file(object):
    def __init__(self, filename, text, mode='w', ):
        self.file = open(filename, mode)
        self.file.write(text)
        try:
            self.close()
        except:
            pass

    def close(self):
        self.file.close()


def main(img_name='exp.jpg'):
    setting_file = open('setting.json', 'r')
    setting = json.load(setting_file)
    t = 0.2
    img = Image.open(img_name)
    img = Img(img).get_img().resize((round(img.width*t), round(img.height*t)))
    text = ''
    for y in range(img.height):
        for x in range(img.width):
            text += Img.getchar(img.getpixel((x, y)))
        text += '\n'
    fo = write_file('ZiFuHua.txt', text)

运行结果及报错内容

Traceback (most recent call last):
  File "D:\py_proj\XingYuan\字符画\字符画.py", line 62, in <module>
    main()
  File "D:\py_proj\XingYuan\字符画\字符画.py", line 34, in main
    setting_file = open('setting.json', 'r')
FileNotFoundError: [Errno 2] No such file or directory: 'setting.json'

我想要达到的结果

它咋就看不着那个文件呢？？

程序缺省目录的问题？
把这两句加到main里，
看看程序目录

import os
print(os.getcwd())
