## Mission 3: Use of Jupyter and notebook

**Date:** June 17, 2025  
**Duration:** Approximately 2 hours  
**Directory:** `mooc-rr/module2/exo1`, `mooc-rr/module2/exo2`, `mooc-rr/module2/exo3`  
**Tools used:** Jupyter Notebook, GitLab, Matplotlib, NumPy

### What I did

- Reproduced a PDF file in order to use some approaches to evaluate the value of pi.
- Entered some daily data manually for analysis purposes.
- Computed basic statistics: mean, standard deviation, minimum, maximum, and median.
- Produced two visualizations: a sequence plot and a histogram.

### What I learned

- Analyzing and visualizing simple data using Python tools.
- Formatting plots clearly in a computational notebook.
- Pushing changes to GitLab during the task.
- Resolving Git conflicts involving Jupyter notebooks.

### Difficulties encountered

At the beginning of the task, I encountered a Git error while trying to push my notebook to GitLab. The error stated that my local branch and the remote branch had diverged, with conflicting changes in the file `toy_notebook_en.ipynb`. Since I had not made any meaningful edits locally, I chose to discard my local version and keep the one on GitLab.

### Notes

Once the Git issue was resolved, I was able to finish the task without further problems.
