[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
