In [5]: a = 5
You can double-check this by typing the following:
In [6]: type(a)Out[6]: int
As the standard Python implementation is written in C, every Python object is basically a C structure in disguise. This is true even for integers in Python, which are actually pointers to compound C structures that contain more than just the raw integer value. Therefore, the default C data type used to represent Python integers will depend on your system architecture (that is, whether it is a 32-bit ...
