Table 3.9 in "Python Essential reference" by Beazley:

Type (built-in)          Size
Integer                  12 bytes
Long Integer             12 bytes + (nbits/16 + 1)*2 bytes
Float                    16 bytes
Complex                  24 bytes
List                     16 bytes + 4 bytes for each item
Tuple                    16 bytes + 4 bytes for each item
String                   20 bytes + 1 byte per character
Dictionary               24 bytes + 12*2^n bytes, n = log2 (nitems)+1
Class Instance           16 bytes + a dictionary object
Xrange object            24 bytes
