Hi Nicole,

I was able to look into the official pandas documentation and I saw that the 'concat()' function is the replacement for append now.

Here is a snippet of the 'concat()' function from the documentation:

"The 'concat()' function concatenates an arbitrary amount of 'Series' or 'DataFrame' objects along an axis while performing optional set logic (union or intersection) of the indexes on the other axes."

"Like 'numpy.concatenate', 'concat()' takes a list or dict of homogeneously-typed objects and concatenates them."

Note: Since the 'record' object is a dict, you have to convert it into a DataFrame before you can concatenate.

I was able to get the same output as Craig by using the following code using Python in Jupyter Notebooks:

# Convert the record into a DataFrame
new_record = pd.DataFrame([record])

# Append the new_record DataFrame with transactions
pd.concat([transactions, new_record], ignore_index=True).tail()
