Python request.py语法错误

Question

我是Python 3.4.5的新手，我通过观看具有C的一些知识的在线视频来在线学习。我正尝试通过Python下载图像，由于该错误，我无法执行此操作。

码：

import random
import urllib.request

def img(url):
  full='name'+'.jpeg'
  urllib.request.urlretrieve(url,full)

img("http://lorempixel.com/400/200")

错误：

Traceback (most recent call last):
  File "image.py", line 2, in <module>
    import urllib.request
  File "/home/yuvi/pyth/urllib/request.py", line 88, in <module>
    import http.client

    _DefragResultBase.url.__doc__ = """The URL with no fragment identifier."""
AttributeError: readonly attribute

Answer 1

尝试：

def img(url): full='name'+'.jpeg';urllib.urlretrieve(url,full)

urllib.request在Python 2.x中不存在，这似乎是您的情况
所以不要尝试将其导入代码的第二行

另外，您编写了一个错字（忘记分号），可在编写内联函数语句时用作语句分隔符。 如同：

def img(url):  
  full='name'+'.jpeg'  
  urllib.urlretrieve(url,full)
