I have a DataFrame df like this.

Number SomeValue SomeOtherValue
  10    10        1.0
  11     3        1.1

when I look at the data frame using df.head(), I get this

  Number SomeValue SomeOtherValue
0  10    10        1.0
1  11     3        1.1

I would like Number to be my index, so I do something like this:

df.index = df.Number
df = df.drop(\'Number\', 1);

This seems a bit clumsy, so is there another way of promoting a column to an index?
