How to append/concat dataframes from within a function to a global dataframe

Question

I have a scraping function that returns a dataframe as such: enter image description here

How can i add this dataframe to a global dataframe as to keep extending my dataframe like so: enter image description here

The result should be a function i can run again and again with different arguments to compile data into my dataframe.

`

def getTicketPrices(IPLocation, X, Y):
    
    #Scraping...
    
    df = pd.DataFrame (price_list_cleaned, columns = [IPLocation])
   

`

I have tried creating a dataframe before the function as such: resultsDF = pd.DataFrame()

and then using trying to use the.concat() method within the function but it returns an empty dataframe...

Answer 1

You can use concat :

appended_df  = pd.DataFrame() # Initilize
appended_df = pd.concat([appended_df, new_df], axis=1)
