Change dictionary values from $ to float value. Python Selenium-CodePudding

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!

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}
