Question

On Pandas documentation of the pivot method, we have:

Examples
--------
>>> df
    foo   bar  baz
0   one   A    1.
1   one   B    2.
2   one   C    3.
3   two   A    4.
4   two   B    5.
5   two   C    6.

>>> df.pivot('foo', 'bar', 'baz')
     A   B   C
one  1   2   3
two  4   5   6

My DataFrame is structured like this:

   name   id     x
----------------------
0  john   1      0
1  john   2      0
2  mike   1      1
3  mike   2      0

And I want something like this:

      1    2   # (this is the id as columns)
----------------------
mike  0    0   # (and this is the 'x' as values)
john  1    0

But when I run the pivot method, it is saying:

*** ReshapeError: Index contains duplicate entries, cannot reshape

Which doesn’t makes sense, even in example there are repeated entries on the foo column. I’m using the name column as the index of the pivot, the first argument of the pivot method call.

Answer 1

Works fine for me? Can you post the exact pivot method call you’re using?

In [4]: df.pivot('name', 'id', 'x')
Out[4]: 
id    1  2
name      
john  0  0
mike  1  0
