capture html screen with pexpect when using python

0 votes
30 views

I can log into a web site with pexpect but what I want to do is pipe the opening window to a file. Logging into the site opens the site window but I can't get the window to a file.

I can't use screen capture I need to get pexpect to pipe it to a txt file.

What have you tried? What environment are you in? What's the exact assignment?
I'd use wget, since I'm on Linux, and it's simple.

$ wget google.com
creates a file called index.html in my cwd

Sorry for the vague title. Probably best to just show you the code that explains it better.

This is a simplified example of what I want to do:

# THIS DOESN'T WORK
from random import choice

class Expr(object):
 """
 Expr(expr, op, val) -> an expression object.
 """

 def __init__(self, expr, op='', val=''):
 self.expr = expr # can be another instance of Expression.
 self.op = op
 self.val = val

 def __str__(self):
 return ("%s %s %s" % (self.expr, self.op, self.val)).strip()

 def expand(self):
 self = Expr(self, choice('+-*/'), choice('12345'))

Then I tried messing around with Expr.__new__() and Expr.__init__() but that didn't work.

The only way I've got it to work is by doing the expanding part outside of the object, by a method of some other class. But I want the Expr class to be responsible for itself. How can I do this and why doesn't the above work?
