IndexError: list index out of range

Hi Shail,

I tried to follow your review on Medium, when I run your code on my machine I got the above error:

here is the full error, and the error is not due to reading from the web address, as that function reads the csv:

I am not sure what more I should provide as this is the first time ever I am raising an issue.

InternalHashError: module 'main' has no attribute 'file'

While caching the body of get_data(), Streamlit encountered an
object of type builtins.function, which it does not know how to hash.

In this specific case, it's very likely you found a Streamlit bug so please
[file a bug report here.]
(https://github.com/streamlit/streamlit/issues/new/choose)

In the meantime, you can try bypassing this error by registering a custom
hash function via the hash_funcs keyword in @st.cache(). For example:

@st.cache(hash_funcs={builtins.function: my_hash_func})
def my_func(...):
    ...

If you don't know where the object of type builtins.function is coming
from, try looking at the hash chain below for an object that you do recognize,
then pass that to hash_funcs instead:

Object of type builtins.function: <function get_data at 0x000001C71433A288>
Object of type builtins.tuple: ('__main__', 'get_data', <function get_data at 0x000001C71433A288>)

Please see the hash_funcs [documentation]
(https://streamlit.io/docs/advanced_caching.html)
for more details.

Above mentioned errors are due to data being old and not available on the hyperlink provided in the code.
Someone can get the dataset from updated URL http://insideairbnb.com/get-the-data.html
Hope it will be helpful.
