DOC: GH3105 better error message on ndarray construction

[jreback]

closes #3105

[hayd]

I never liked that error message, will be glad to see it die.

Most likely I am missing something, but are these tests asserting anything? Should each test include something similar to:

self.assert_(detail.message.startswith("Shape of passed values"))

.

(I'm afraid I can't help mentioning):

tuple([len(index),len(columns)]) == (len(index),len(columns))

[jreback]

yah...prob should be asserting....

what' s the 2nd part of your message?

[hayd]

Looks like python3 doesn't give .message attribute to ValueError... hmmm.

Second part is simply that: required_shape = tuple([len(index),len(columns)]) could read required_shape = (len(index),len(columns)) :)

try:
    raise ValueError("foo")
except (Exception), detail:
    assert(str(detail).startswith("foo"))

@y-p @hayd thanks....just figured that out!

also was missing some cases, so did a bit of refactoring to make it consistent

[jreback]

@hayd Andy on a side note, you are very patient with people on stackoverflow!

[hayd]

@jreback Thanks! I try not to think about it... :)

[jreback]

[ghost]

[hayd]

@jreback I have only just looked at the google groups page... right back at you!
