On running the code it's only showing 4 columns instead of 8...I'm pretty sure the code is correct, why is this happening?

Question

[15 rows x 8 columns]

Answer 1

Try to remove the limit on the number of displayed columns with:

pd.options.display.max_columns = None

The dataframe has 8 columns, it's just that not all are shown.

Answer 2

It is due to space ( width) that you see only four columns( the first two and last two) and the rest are represented by the three dots "...". There is nothing wrong except that pandas shows partially due to spacing ( width).

Answer 3

print(df) hides some columns by default.

You could either change the pandas display options mentioned by @user2314737, or you could try df.head() instead.
