Hi @dadp2551,

Thanks for sharing your project with the Community! You’ve done a great job: the project is well-structured, your storytelling is laconic but clear and informative, the graphs are cool and clean, with a good choice of colors and sizes. I liked your findings on speed limit adjustment in 2017. Also, well done on doing the extra steps!

Some suggestins:

  • You can consider creating functions for the plots of the same type, to avoid code repetition.
  • A good idea is to import all the libraries in the 1st code cell.
  • When the project is already ready, it’s better to re-run it to have all the code cells in order and starting from 1.
  • Consider removing the grids and unnecessary spines from your graphs. Also, it’s better to remove the x-axis label “Months” since it’s quite evident.
  • A good practice is to put in backticks column names and variables mentioned in markdown.

Hope my suggestions were helpful. Happy learning and good luck with your future projects!

Hi, Dataquest community!

I was planning to open a new post but I thought it would be better to share here the correction of the guided project N° 04.

I appreciate your suggestions and comments.

Happy coding!

Hi @dadp2551,

Wow, really super-cool job updating your project! :star_struck: Everything is just perfect now, I especially liked the choice of corresponding colours for day and night, clean visualisations, smooth storytelling, and emphasizing the most important points throughout the project! This time, I really have no suggestions, which rarely happens to me :joy: Keep up your very high level of projects and this speed and at the same time high-quality learning pace! :heavy_heart_exclamation:

I would like to take advantage of the fact that I’m here to correct some small details in this project :sweat_smile:. In the function ‘bins_number_col’, located in cell 5, there is an unnecessary parameter (col) and three unnecessary lines of code:

  • min_ = df[col].min()
  • max_ = df[col].max()
  • range_ = max_ - min_

I’m reusing parts of code from previous projects and have overlooked these small but important details. Also, I have corrected redundant values in the first table of the results summary section.

From now on, I will be more careful and review the projects well before publishing them.

I’m going through challenging days, but I’m still correcting the projects I still have pending. I’ll be posting them soon.

Have a nice day and happy coding!!
