plotly : Difficulty in displaying a string with two dollar signs in plot annotation

Question

I have a string with two dollar sign, and I want to be used as a text annotation below my plot. This code created a string, and you can see its output.

str=f"Maximum: {a} , ${numerize.numerize(b)}\t"+f"Minimum: {c} , ${numerize.numerize(d)}"

Output: Maximum: 1396 , $544.41M Minimum: 1399 , $255.31M

but when I use str in below, plotly changes the font and shows unexpected characters:

annotations = []
annotations.append(dict(xref='paper', yref='paper', x=0.5, y=-0.15,
                              xanchor='center', yanchor='top',
                              text=str,
                              font=dict(family="Courier New",
                                        size=14,
                                        color='rgb(100,100,100)'),
                              showarrow=False))
fig.update_layout(annotations=annotations)

and the result in the plot: unexpected annotation

How can I fix this issue? Thanks.

• Plotly: How to use both dollar signs and linebreaks in annotations? need to use HTML printable characters in text that becomes HTML
• hence solution becomes

import plotly.graph_objects as go
from numerize import numerize

fig = go.Figure()

# # Output: Maximum: 1396 , $544.41M Minimum: 1399 , $255.31M
a = 1396
b = 544.41 * 10 ** 6
c = 1399
d = 255.31 * 10 ** 6
str = (
    f"Maximum: {a} , ${numerize.numerize(b)}\t"
    + f"Minimum: {c} , ${numerize.numerize(d)}"
)
ano
annotations = []
annotations.append(
    dict(
        xref="paper",
        yref="paper",
        x=0.5,
        y=-0.15,
        xanchor="center",
        yanchor="top",
        text=str,
        font=dict(family="Courier New", size=14, color="rgb(100,100,100)"),
        showarrow=False,
    )
)
fig.update_layout(annotations=annotations)
