Thanks, for the `collections.abc.ValuesView` tip.
The code in question is part of an attempt to get the dimensions of
multi-dimensional lists, the `isinstance` is there in order to
exclude strings.
"""
def dim(seq):
dimension = []
while isinstance(seq, (list, tuple)):
dimension.append(len(seq))
try:
seq = seq[0]
except IndexError: # sequence is empty
break
return dimension
