copied!<p>The question is somewhat ambiguous -- I'm not sure what you mean by "view". If you are trying to <em>query</em> the type of a native Python object, <a href="https://stackoverflow.com/questions/402504/how-to-determine-the-variable-type-in-python#402516">@atzz</a>'s answer will steer you in the right direction.</p> <p>However, if you are trying to <em>generate</em> Python objects that have the semantics of primitive C-types, (such as <code>uint32_t</code>, <code>int16_t</code>), use the <a href="http://docs.python.org/library/struct.html#struct.calcsize" rel="nofollow noreferrer"><code>struct</code></a> module. You can determine the number of bits in a given C-type primitive thusly:</p> <pre><code>>>> struct.calcsize('c') # char 1 >>> struct.calcsize('h') # short 2 >>> struct.calcsize('i') # int 4 >>> struct.calcsize('l') # long 4 </code></pre> <p>This is also reflected in the <code>array</code> module, which can make arrays of these lower-level types:</p> <pre><code>>>> array.array('c').itemsize # char 1 </code></pre> <p>The maximum integer supported (Python 2's <code>int</code>) is given by <a href="http://docs.python.org/library/sys.html#sys.maxsize" rel="nofollow noreferrer">sys.maxint</a>.</p> <pre><code>>>> import sys, math >>> math.ceil(math.log(sys.maxint, 2)) + 1 # Signedness 32.0 </code></pre> <p>There is also <a href="http://docs.python.org/library/sys.html#sys.getsizeof" rel="nofollow noreferrer">sys.getsizeof</a>, which returns the actual size of the <em>Python</em> object in residual memory:</p> <pre><code>>>> a = 5 >>> sys.getsizeof(a) # Residual memory. 12 </code></pre> <p>For float data and precision data, use <a href="http://docs.python.org/library/sys.html#sys.float_info" rel="nofollow noreferrer">sys.float_info</a>:</p> <pre><code>>>> sys.float_info sys.floatinfo(max=1.7976931348623157e+308, max_exp=1024, max_10_exp=308, min=2.2250738585072014e-308, min_exp=-1021, min_10_exp=-307, dig=15, mant_dig=53, epsilon=2.2204460492503131e-16, radix=2, rounds=1) </code></pre>
