Python Regex Not Working

I am using the following code: downloadlink = re.findall('http://uploadir.com/u/(.*)\b', str(downloadhtml)) However, when I pass it the following string:

Solution 1:

Get in the habit of making all regex patterns with raw strings:

In [16]: re.findall("http://uploadir.com/u/(.*)\b", '<input type="text" value="http://uploadir.com/u/bb41c5b3" />')
Out[16]: []

In [17]: re.findall(r"http://uploadir.com/u/(.*)\b", '<input type="text" value="http://uploadir.com/u/bb41c5b3" />')
Out[17]: ['bb41c5b3']

The difference is due to \b being interpreted differently:

In [18]: '\b'
Out[18]: '\x08'

In [19]: r'\b'
Out[19]: '\\b'

'\b' is an ASCII Backspace, while r'\b' is a string composed of the two characters, a backslash and a b.

Solution 2:

>>>import re>>>html = '<input type="text" value="http://uploadir.com/u/bb41c5b3" />';>>>regex = r'http://uploadir.com/u/([^"]+)'>>>link = re.findall(regex, html)>>>link
['bb41c5b3']
>>>
