I cannot download the files hosted on this book

Append not working in new version pandas

the code on page 104 is not working:

test_df = itunes_df.copy()
test_df = test_df.append(itunes_df.loc[3502])
test_df.loc[3502]

I think this must be:

test_df = itunes_df.copy()
example_row = itunes_df.loc[[3502]]
test_df = concat([test_df, example_row])
test_df.loc[3502]

Chapter 7 page 207 variable "datafile" declaration and calling

In chapter 7 on page 207 the variable are decleare as:

datafile = 'https://docs.misoenergy.org/marketreports/20210203_mom.xlsx' mom_data = urlopen(datafile_url).read() print(mom_data[:20])

In theory it should be:
datafile_url= 'https://docs.misoenergy.org/marketreports/20210203_mom.xlsx' mom_data = urlopen(datafile_url).read() print(mom_data[:20])

I have check the cooresponding ipynb file on github its correct there. The updates will help in correction for next version.
