Change dictionary values from $ to float value. Python Selenium

I have scraped 3 different websites and obtained 3 different values with corresponding keys.
I want to divide these values by 2 before I pass them through Venmo to make a request. However, I have not figured out a way to do this in a way that will result in halving these amounts.

My current dictionary outputs as such:

{'Water': '$0.00', 'Electric': '$42.78', 'Gas': '$272.65'}

At the end of the website scraping I was thinking to grab these keys and divide them by a dictionary that looks like this:

{'Water': '2', 'Electric': '2', 'Gas': '2'}

Before I do so, I have to pass the first dictionary as float values.

Any ideas as to what the best way to do this is after having the dictionary established?

Thanks!

>Solution :

You can chop off the first character to remove the dollar sign, and then transform the sliced string into a float:

data = {'Water': '$0.00', 'Electric': '$42.78', 'Gas': '$272.65'}
divisors = {'Water': '2', 'Electric': '2', 'Gas': '2'}
result = {key: float(value[1:]) / float(divisors[key]) for key, value in data.items()}

print(result) # Prints {'Water': 0.0, 'Electric': 21.39, 'Gas': 136.325}
