(Sorry for top posting): You are mad! Why on God's earth would you want to create a list containing 60 MILLION elements ?
What is the use case ? What are you solving ? You may have 4G of ram, but I very seriously doubt you have 4G of ram available to Python. I have no idea how many bytes of memory storing each element of a list consumes let alone each float object, but I assure you it's not going to be anywhere near that of 60494500 4-bytes spaces (do floats in C normally consume 4 bytes) in C. --JamesMills -- -- "Problems are solved by method" On Wed, Dec 31, 2008 at 4:02 PM, [BON] <alo...@live.co.kr> wrote: > > ====================== > s=[] > for i in range(11000-1): > for j in range(i+1, 11000): > .... > s.append(((i,j),sim)) > ====================== > above sim is floating type. > s.append is totally coducted 60,494,500 times. > but this code raise MemoryError. > > My computer has 4G RAM. > i think it's enough. but it doesn't... > > So, i've tested below code. > ====================== > a=[] > i=0 > while i<60494500 : > a.append(i) > i+=1 > ====================== > but this code raise also MemoryError. > > How can i resolve this problem? > please, help... > > Regards, > -- > View this message in context: > http://www.nabble.com/MemoryError-when-list-append...-plz-help-tp21227745p21227745.html > Sent from the Python - python-list mailing list archive at Nabble.com. > > -- > http://mail.python.org/mailman/listinfo/python-list > -- http://mail.python.org/mailman/listinfo/python-list
