[Numpy-discussion] Printing formatted numerical values

2010-11-15 Thread pv+numpy
Hi, what is the best way to print (to a file or to stdout) formatted numerical values? Analogously to C's printf("%d %g",x,y) etc? Numpy Documentation only discusses input *from* a file, or output of entire arrays. (np.savetxt()) I just want tab or space-delimited output of selected formatted v

[Numpy-discussion] getitem and slice

2010-11-15 Thread Keith Goodman
There is more than one way to form the same slice. For example, a[:2] and a[0:2] and a[0:2:] pass slice objects to getitem with the same start, stop and step. Is there any way to get a hold of the exact character sequence the user used to form the slice? That is, I'd like to know if the user entere

Is there a convention for dealing with NaN and Inf? I've found that trusting the default behavior is a very bad idea: --- from numpy import * x = zeros((5,7)) x[:,3:] = nan x[:,-1] = inf savetxt('problem_array.txt',x,delimiter='\t') x2 = loadtxt('problem_array.txt'

[Numpy-discussion] dtypes error in recfunctions

2010-11-15 Thread Benjamin Root
Hello, I was using append_fields() in numpy.lib.recfunctions when I discovered a slight logic mistake in handling the dtypes argument. The code first checks to see if dtypes is None. If so, it then guesses the dtype info from the input data. Then, it goes to see if the dtypes is not a sequence
