Thanks but forgive me for being really dense I'm still not sure how to resolve this after reading that link. Am I to define the variable as global or insert "df = pd.DataFrame(data) df.to_csv("jan_1") inside the code somewhere? I've tried both with no success.

From your code it isn't clear where thedf = pd.DataFrame(data)is or should be placed. Depending on the context it may be placed into thefor-loop inmain. Asscrapereturns the data you could there writedata = scrape(url)and after that thedf = pd.DataFrame(data).

Unfortunately thedata = [main]also doesn't make much sense anddataisn't filled with the real data. Your code may have too many issues to solve them here.

Thanks but forgive me for being really dense I'm still not sure how to resolve this after reading that link. Am I to define the variable as global or insert "df = pd.DataFrame(data) df.to_csv("jan_1") inside the code somewhere? I've tried both with no success.

From your code it isn't clear where thedf = pd.DataFrame(data)is or should be placed. Depending on the context it may be placed into thefor-loop inmain. Asscrapereturns the data you could there writedata = scrape(url)and after that thedf = pd.DataFrame(data).

Unfortunately thedata = [main]also doesn't make much sense anddataisn't filled with the real data. Your code may have too many issues to solve them here.

From your code it isn't clear where the
df = pd.DataFrame(data) is or should be placed. Depending on the context it may be placed into the for-loop in main. As scrape returns the data you could there write data = scrape(url) and after that the df = pd.DataFrame(data).– Michael Butscher
