<p>关于熊猫的文档有很多信息。</p>
<blockquote>
<p>The main types stored in pandas objects are float, int, bool,
datetime64[ns], timedelta[ns], and object. In addition these dtypes
have item sizes, e.g. int64 and int32.</p>
<p>By default integer types are int64 and float types are float64,
REGARDLESS of platform (32-bit or 64-bit). The following will all
result in int64 dtypes.</p>
<p>Numpy, however will choose platform-dependent types when creating
arrays. The following WILL result in int32 on 32-bit platform.</p>
