python - 尝试创建文件时出现 ValueError 未知 url 类型

Question

我使用 open(os.path.abspath(os.curdir) + "/children.csv", "w") 创建数据并将其写入当前目录中的文件。当我运行此命令时，出现以下错误:

ValueError: unknown url type: '/Users/EL-CAPITAN-2016/Downloads/children.csv'

我尝试仅使用 open("children.csv","w")，但它给了我同样的错误。 我尝试手动创建文件并使用其 URL 仅使用 open("/Users/EL-CAPITAN-2016/Downloads/children.csv","r") 读取文件，但再次出现相同的错误

创建并写入文件的代码:

from urllib.request import urlopen as open
import os
print(os.path.abspath(os.curdir))
f = open(os.path.abspath(os.curdir) + '/children.csv','w')

我用来读取手动创建的文件的代码:

from urllib.request import urlopen as open
import os
print(os.path.abspath(os.curdir))
f = open('/Users/EL-CAPITAN-2016/Downloads/children.csv','r')

我收到的错误日志如下:

Traceback (most recent call last):
  File "children.py", line 7, in <module>
    f = open('children.csv','r')
  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/urllib/request.py", line 222, in urlopen
    return opener.open(url, data, timeout)
  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/urllib/request.py", line 510, in open
    req = Request(fullurl, data)
  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/urllib/request.py", line 328, in __init__
    self.full_url = url
  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/urllib/request.py", line 354, in full_url
    self._parse()
  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/urllib/request.py", line 383, in _parse
    raise ValueError("unknown url type: %r" % self.full_url)
ValueError: unknown url type: '/Users/EL-CAPITAN-2016/Downloads/children.csv''

正如 Shuvojit 和 OP 所发现的那样，问题在于将 urlopen 导入为 open 替换了内置 open

from urllib.request import urlopen as open
