If you often use interactive IPython sessions or Jupyter Notebooks and you’re getting tired of importing the same libraries over and over, try this:

Navigate to ~/.ipython/profile_default
Create a folder called startup if it’s not already there
Add a new Python file called start.py
Put your favorite imports in this file
Launch IPython or a Jupyter Notebook and your favorite libraries will be automatically loaded every time!

    Add labels to the end of each bar in a barh chart.

    Tip: usually one need to add expansion of xlimit to keel labels inside plot, e.g.:
    ax.set_xlim(0, 1.1)
    
    Arguments:
        ax (matplotlib.axes.Axes): The matplotlib object containing the axes
