Color coding numbers in Python similar to Excel conditional formatting

Is there a module or any workarounds in Python to color code numbers from 0 to 100 going from red to green? I'm trying to better visualize a score by changing the font color based on the number but don't want to reinvent the wheel. Thought I could find myself 100 different colors and make a dictionary out of it but wanted to ask the community in advance. Many thanks.

NOTE: I am using Python, Flask, and HTML. I need a simple function/module that I can plug a number into to output a corresponding color in hex.

Perhaps try to separate the colors into 10 buckets instead of 100, then make a list out of it.

colors = ["#first", "#second", "#third", ..., "#tenth"]

Then, write a simple function to assign the number to the corresponding color.

def pick_color(num):
    if num in range(0, 10):
        return colors[1]
    elif num in range(10, 20):
        return colors[2]

...and so on.

Everything you need for this can be found in the matplotlib.

In Pandas, you can use the following code to get the picture attached. You will need Pandas, Numpy for rounding, and you may need Matplotlib as well.

(np.round(df.corr().iloc[:-1, :], 6).style.format({}) .background_gradient(cmap='RdYlGn', low=.4, high=.4))
