Python FileNotFoundError: [Errno 2] 沒有這樣的文件或目錄：

Question

我正在嘗試打開目錄中的所有“*.json”文件並從中獲取一些數據

import json
import os #os module imported here
import glob

path = 'C:\Saba\Python Workspace'

for filename in os.listdir(path):
    if filename.endswith('.json'):
        with open(filename,'r') as f:
            data = json.load(filename)
            print(data['key'],end="*")
            for path in data['paths']:
                print(path['method'],end="*")
                for resources in path['resources']:
                    print(resources['key'],end="*")

print("\b"+"$")

這是我得到的錯誤：

Traceback (most recent call last):
  File "c:/Saba/Python Workspace/folder.py", line 9, in <module>
    with open(filename,'r') as f:
FileNotFoundError: [Errno 2] No such file or directory: 'order-securityTransferOrders-service-v1.0.0-inventory.json'

Answer 1

您正在不同的路徑中運行腳本。 添加文件名的絕對路徑即可解決問題。

import os.path
for filename in os.listdir(path):
    abs_file_path = os.path.abspath(filename)
    if filename.endswith('.json'):
        with open(abs_file_path,'r') as f:
        # your code .... 

Answer 2

你在哪里運行這個腳本？ Python 嘗試在當前腳本文件夾中搜索您的 Json 文件。

如果你想讓 Python 在給定的路徑中找到，你應該像這樣寫：

with open(os.path.join(path,filename) ,'r') as f:

Answer 3

with open(filename,'r') as f:替換 line with open(filename,'r') as f: with with open(os.path.abspath(filename),'r') as f:
