Complete the code to save a custom style dictionary to a file named 'mystyle.mplstyle'.

Matplotlib

style_dict = {'lines.linewidth': 2, 'axes.titlesize': 14}
with open('[1]', 'w') as f:
    for key, value in style_dict.items():

💡 Hint

Common Mistakes

Saving the style with a wrong file extension.

Using a filename that matplotlib won't recognize as a style sheet.

The custom style sheet must be saved with the extension .mplstyle for matplotlib to recognize it.

Fill all three blanks to create a style dictionary that sets font size to 12 for axes titles, font family to 'serif', and line color to 'red'.

Matplotlib

style_dict = {
    'axes.titlesize': [1],
    'font.family': [2],
    'lines.color': [3]
