# Create empty dataframe with row names
empty_dataframe = pd.DataFrame(index=['your', 'row', 'names'])empty dataframe
newDF = pd.DataFrame() #creates a new dataframe that's empty
newDF = newDF.append(oldDF, ignore_index = True) # ignoring index is optional
# try printing some data from newDF
print newDF.head() #again optionalinitialize pandas dataframe with column names
column_names = ["a", "b", "c"]
df = pd.DataFrame(columns = column_names)create empty pandas dataframe
df = pd.DataFrame(columns=['a', 'b', 'c'])create an empty dataframe
