In Python, how big can a list get? I need a list of about 12000 elements. Will I still be able to run list methods such as sorting, etc?
According to the source code, the maximum size of a list is
PY_SSIZE_T_MAX is defined in pyport.h to be
On a regular 32bit system, this is (4294967295 / 2) / 4 or 536870912.
Therefore the maximum size of a python list on a 32 bit system is 536,870,912 elements.
As long as the number of elements you have is equal or below this, all list functions should operate correctly.
As the Python documentation says:
The largest positive integer supported by the platform’s Py_ssize_t type, and thus the maximum size lists, strings, dicts, and many other containers can have.
In my computer (Linux x86_64):
>>> import sys >>> print sys.maxsize 9223372036854775807
