Can you please explain what you mean by _re-initialize the list_ ?

Can you explain why the following won't work?
#!/usr/bin/python
import sys
import gzip
# At the moment not bother with argument part as I am testing it with a

#fileIn = gzip.open(sys.argv[1])
fileIn = gzip.open('big_log_file.gz', 'r')
fileOut = open('outputFile', 'a')
for line in fileIn:
while line != 'blank_line':

fileOut.write(line)

Re: [Tutor] Python on Ubuntu 10.10?
Python comes pre installed on Ubuntu, as most of the GUI is written in it. Nick On Friday, January 14, 2011, Joel Knoll wrote: > > > > > > Hello, > > I am new to programming and to Python.

Re: [Tutor] OOP question
If you want to test if one outcome is equal to another, you probably want to know if The name of the outcome is the same The odds of the outcome is the same So, you'd implement it like so class Outcome: def __eq__(self, other): if self.name == other.name and self.odds == other.odds: return True return False Make sense?
