Hello, here a diff between the python3.6 and python3.7 modules once updated via 2to3.
r:/tmp$ diff core* 174c174 < for (variance, tag) in zip(variances, tags)) --- > for (variance, tag) in list(zip(variances, tags))) 181c181 < for (coords, value) in zip(transform, nom_values)) --- > for (coords, value) in list(zip(transform, nom_values))) 946c946 < ord(sup): normal for (normal, sup) in TO_SUPERSCRIPT.items()} --- > ord(sup): normal for (normal, sup) in iter(TO_SUPERSCRIPT.items())} 1776c1776 < delta**2 for delta in self.error_components().values()))) --- > delta**2 for delta in iter(self.error_components().values())))) can python expert explain if this seems correct or not ? thanks for your help.
