Ex 4.4

[MattiasNilsson95]

Hi there!

This comes a little bit late, but I am having an issue with exercise 4.4 which possibly stems from a mistake in 4.3, and I would appreciate some help even if it comes after the assignment deadline.

When I try adding a column to the subset from 4.3 I recieve the following error:

I.e. I don't seem to be able to add a column, using the method specified erlier in the document, to the df_select as it is a copy of another dataframe. Is supposed to be the case or have I done something wrong?

This is what I did for exercise 4.3:

Note: For the moment I have worked around the issue simply by adding the column straight to df_weather.

Best,
Mattias

Hi Mattias,

I hope you can live with a brief answer here, but instead of creating df_copy, do the line of operations directly on df_weather, instead. Then finish off with .copy() after the end bracket. Does this work?

Best,
Joachim

Hi Joachim, Many thanks for your email and rapid help! This sounds promising, I will attempt it after work. Unfortunately it will be after the deadline, but it will be equally useful for my self development! In the meanwhile I sent in the assignment zero with what I was able to do, hope that is alright. Best, Mattias

Great. It should not be a problem that you have not included this in your answer - learning is priority with this assignment!

Best,
