What is the easiest way to save and load data in python, preferably in a human-readable output format?
The data I am saving/loading consists of two vectors of floats. Ideally, these vectors would be named in the file (e.g. X and Y).
There are several options -- I don't exactly know what you like. If the two vectors have the same length, you could use
numpy.savetxt() to save your vectors, say
y, as columns:
# saving: f = open("data", "w") f.write("# x y\n") # column names numpy.savetxt(f, numpy.array([x, y]).T) # loading: x, y = numpy.loadtxt("data", unpack=True)
If you are dealing with larger vectors of floats, you should probably use NumPy anyway.
