Creating a Pandas DataFrame from a Numpy array: How do I specify the index column and column headers?
I have a Numpy array consisting of a list of lists, representing a two-dimensional array with row labels and column names as shown below:
data = array([['','Col1','Col2'],['Row1',1,2],['Row2',3,4]])
I'd like the resulting DataFrame to have Row1 and Row2 as index values, and Col1, Col2 as header values
I can specify the index as follows:
df = pd.DataFrame(data,index=data[:,0]),
however I am unsure how to best assign column headers.
