python - Encountered a problem when crawling images. urllib.request.urlretrieve failed to download to the specified folder?
There is no problem if you download to the D drive, but there is a problem when downloading to the directory I created (mainly because I want to create a directory on the D drive named with the number in front of the question mark in the URL, such as (http://v .yupoo.com/photos/196...') is not possible because there are many links and the number of each link is different. I want to use this number as the name of the folder to store the pictures downloaded from this link. )
The source code is as follows: 
import urllib.request
import re
import os
py grabs the page image and saves it locally
Get page information
url_all =['http://v.yupoo.com/photos/196...',
'http://v.yupoo.com/photos/196...',
'http://v.yupoo.com/photos/196...',
'http://v.yupoo.com/photos/196...',]
def getHtml(url):
html = urllib.request.urlopen(url).read()
return html
Get images through regular expressions
def getImg(html):
reg = 'src="(.+?\.jpg)"'
imgre = re.compile(reg)
imglist = re.findall(imgre,html)# print(imglist)
return imglist
for i in range(len(url_all)):
Loop to save pictures locally
html = getHtml(url_all[i])
list=getImg(html.decode())print (url_all[1])
x = 0
for imgurl in list:
print(x)
filename = os.path.dirname(url_all[i])
filename2 = os.path.basename(filename)os.mkdir('d:\%s'% filename2)
local='D:\%s\%s.jpg' %(filename2,x)
print (local)
urllib.request.urlretrieve(imgurl,local)
x+=1print("done")
Execution error: (win10 64-bit system, python3.6)
File "C:Python36liburllibrequest.py", line 258, in urlretrieve
tfp = open(filename, 'wb')
FileNotFoundError: [Errno 2] No such file or directory: 'd:\46975340\0.jpg'
After testing
The last sentence written like this can be output: urllib.request.urlretrieve(imgurl,'d:\%s.jpg'% str(i*10 x))
After testing, the first two sentences are ok, add the third sentence:
local='d:\%s\%s.jpg' %(filename2,x)
print (local)
urllib.request.urlretrieve(imgurl,local)
The error message is as follows: (Same as above)
File "C:Python36liburllibrequest.py", line 258, in urlretrieve
tfp = open(filename, 'wb')
FileNotFoundError: [Errno 2] No such file or directory: 'd:\46975340\0.jpg'
Could you please tell me, is there any problem with this path? How should it be written.
