title: What are the available datatypes for 'dtype' with NumPy's loadtxt() an genfromtxt?
body: <p>What are the available <a href="http://docs.scipy.org/doc/numpy/reference/generated/numpy.loadtxt.html" rel="noreferrer">numpy.loadtxt</a> or <a href="http://docs.scipy.org/doc/numpy/reference/generated/numpy.genfromtxt.html" rel="noreferrer">numpy.genfromtxt</a> for importing table data with varying datatypes, and what are the available abbreviations for the use (e.g. <strong>i32</strong> for integer)?</p>
  
  <p><a href="https://stackoverflow.com/questions/5660612/numpy-using-loadtxt-or-genfromtxt-to-read-a-ragged-structure">This post</a> demonstrates the use of conditions, which I was curious if somebody might elaborate on.</p>
