[newbie] plotting pairs of data

[hugocoolens]

I have a data set for which x and y-values are presented as pairs of
floating point numbers:
e.g. 0.0364771 0.55569 is the first pair
.. 0.132688 0.808496 is the second pair
..
..

The data is available in Python in this format:
['0.0364771 0.55569', '0.132688 0.808496', '0.232877 0.832833',
'0.332702 0.849128', '0.432695 0.862158']

I suppose it is possible to plot x versus y using matplotlib, maybe
separating the data first in two arrays, but I'm not sure whether this
is necessary.
Can anyone here help me further

thanks
hugo

The data is available in Python in this format:
['0.0364771 0.55569', '0.132688 0.808496', '0.232877 0.832833',
'0.332702 0.849128', '0.432695 0.862158']

I suppose it is possible to plot x versus y using matplotlib, maybe

is necessary.

I think, yes it is necessary to split the data in separate
lists/arrays. Although I find it annoying, too.

In case that not only the if, but also the how is the matter of your
question something like

xs = [ float(x) for x, _ in map(str.split, l) ]
ys = [ float(y) for _, y in map(str.split, l) ]

should do the trick.

['0.0364771 0.55569', '0.132688 0.808496', '0.232877 0.832833',
'0.332702 0.849128', '0.432695 0.862158']

xs = [ float(x) for x, _ in map(str.split, l) ]
ys = [ float(y) for _, y in map(str.split, l) ]

Let's play golf
xs, ys = zip(*(map(float, s.split()) for s in l))
