load signed data joins problem

Community matplotlib-users

I think that not all de numbers use the same number of characters, the problem is the signed ones. This numbers use one more character for ‘-’ and join the previous column.
Your idea is quite good, but I don’t know how to do it:
If I use the pylab.load code, I suppose that I have to put something in “converters” option, but I haven’t found how to use it.
The other option I have found is using ‘readline’ of python

fin = open (file, ‘r’)
datos1 = fin.readline()
fin.close()

but I don’t know how to split it and it seems a very rude way of doing it.

Thank you very much

Looks like all the numbers use the same number of characters – try splitting 16 characters at a time off, and then interpreting those substrings as numbers.

Hi,
I found a problem loading data: I have a file of signed numbers like:

-1.370674456E+02-1.662854139E+02 0.000000000E+00 0.000000000E+00 0.000000000E+00
6.964865599E+10 8.394798002E-11 4.348192658E+03 9.455873862E+02 3.292484968E-09

The problem is that the signed numbers join so I always find an error if I try to load this data.

Any idea of how to bypass it?

Thank you!

How about

f = open(file)
s = f.read()
f.close()
a = s.replace('E-','EE').replace('-',' -').replace('EE','E-')
x = np.fromstring(a, sep=' ')
