Better `repr` for `string.templatelib.Template`.

Feature or enhancement

Proposal:

Currently the repr output for template strings shows how the data is stored internally, but this is not how the template could be reconstructed via an constructor call and the format is unintuitive since the template parts are not output in the order they appear in the template source. The repr result should output the parts in the order as iterating over the template object does, i.e.

x = 1
y = 2
print(repr(t'{x} + {y}'))

should print

Template(Interpolation(1, 'x', None, ''), ' + ', Interpolation(2, 'y', None, ''))

instead of

Template(strings=('', ' + ', ''), interpolations=(Interpolation(1, 'x', None, ''), Interpolation(2, 'y', None, '')))

I'm working on a patch/pull request.

Has this already been discussed elsewhere?

Commencez par le comportement de repr de string.templatelib.Template décrit dans l’issue et comparez-le avec l’itération sur un objet Template. Vérifiez que repr produit les parties de Template dans l’ordre d’itération et correspond au format proposé d’appel du constructeur ; gh-151104 est lié, examinez donc ce travail avant de commencer.
