I was also able to create a 1GB string on a different system (Linux 2.4.x,
32-bit Dual Intel Xeon, 8GB RAM, python 2.2).
$ python -c 'print len("m" * 1024*1024*1024)'
1073741824
I agree with another poster that you may be hitting Windows limitations
rather
than Python ones, but I am certainly not familiar with the details of
Windows
memory allocation.

Here my experience with hunting after the memory limit exactly the way Jeff
did it (Windows 2000, Intel Pentium4, 3GB RAM, Python 2.4.2):
\>python -c "print len('m' * 1024*1024*1024)"
1073741824
\>python -c "print len('m' * 1136*1024*1024)"
1191182336
\>python -c "print len('m' * 1236*1024*1024)"
Traceback (most recent call last):
File "<string>", line 1, in ?
MemoryError
Anyone on a big Linux machine able to do e.g. :
\>python -c "print len('m' * 2500*1024*1024)"
or even more without a memory error?
I suppose, that on the Dual Intel Xeon, even with 8 GByte RAM the upper
limit for available memory will be not larger than 4 GByte.
Can someone point me to an Intel compatible PC which is able to provide more
than 4 GByte RAM to Python?
