Python matplotlib manipulating to use it in the plot title

Question

assume I've the following variable

roundi = theta_result_lasso.round(2)
[ 0.   -2.36]

where theta_result_lasso.round are just two values.

The line for my plot title is

ax.set_title(r'Globales Minimum $\hat \beta$ = {}'.format(roundi), fontsize=20)

producing this:

is there a way to replace the "." after the zero by a "," and descreasing the disance between the two values as it should look like a "vector" ?

It should look like this:

[0, -2.36]

If you Need further informations, I'll provide an example

If your array consist of two variables every time, the easiest would be to format your string something like the following

roundi = [0.0,-2.36]
titlestring = 'Globales Minimum $\hat \beta$ = [{:0.0f}, {:0.2f}]'.format(roundi[0],roundi[1])

The values in roundi are accessed and formatted individually here. This will result in the following formatting

'Globales Minimum $\\hat \x08eta$ = [0, -2.36]'

Use this:

ax.set_title(r'Globales Minimum $\hat \beta$ = {}'.format(str(roundi) ), 
fontsize=20)

This would result in [ 0, -2,36] (two commas)
