Data type objects (dtype) — NumPy v1.24 Manual

WebYou can use NumPy from Cython exactly the same as in regular Python, but by doing so you are losing potentially high speedups because Cython has support for fast access to NumPy arrays. Let’s see how this works with a simple example. WebWith a Python byte string object, you would normally just call the .decode () method to decode it into a Unicode string: ustring = byte_string.decode('UTF-8') Cython allows you to do the same for a C string, as long as it contains no null bytes: cdef char * some_c_string = c_call_returning_a_c_string() ustring = some_c_string.decode('UTF-8') can ipass be used for ezpass
