How do I export multiple pivot tables from python using pandas to a single csv document?

Question

Say I have a function pivots() which aggregates pivot tables

def pivots():
    d = data() #another function which cleans up my raw data
    price_floor = PF(d)
    no_floor = NF(d)
    return price_floor,no_floor

I know how to export a single pivot table

q,r = pivots()
q.to_csv('C:\\export.csv')

But it would be so much more convenient if I could export both price_floor and no_floor to the same document 'export.csv'

You can use to_csv(path, mode='a') to append files.

# default 'w' write mode
q.to_csv('C:\\export.csv')

# explicitly specify 'a' append mode
r.to_csv('C:\\export.csv', mode='a')

# Use header=False
# if you don't want to write headers while appending
r.to_csv('C:\\export.csv', mode='a', header=False)
