Old code reads HTML and output it to CSV
I have an old python 3 code:
self.df, = pandas.read_html(my_html_file)
self.df.to_csv(my_csv_file, index=False)
without comma in first line pandas returns a list, with the comma DF object that can be send to CSV file in second line. I do not understand that comma in the first line
I think it convert one element list to scalar by one element tuple, because read_html return list of DataFrames - in your code one DataFrame list.
Sample:
a = [1]
b, = a
#() are optional
#(b,) = a
print (b)
1
More readable is select first list by indexing - [0]:
self.df = pandas.read_html(my_html_file)[0]
self.df.to_csv(my_csv_file, index=False)
