How can i make this float formatting cleaner?-CodePudding

i am given a value e.g. $50.00. The output should be 50.0. Is there a way to make this cleaner? Especially my use of double float is bothering me

float(f"{float(d.removeprefix('$')):.1f}")

Assuming you're working with monetary amounts then this might give you more reliable results:

for d in '$50.99', '$50.00', '49.99':   
    print(float(f"{float(d.removeprefix('$')):.2f}"[:-1]))

Or...

for d in '$50.99', '$50.00', '49.99':   
    print(int(float(d.removeprefix('$'))*10)/10)

Output:

50.9
50.0
49.9

You can use round function to limit the result to one decimal.

round(float(d.removeprefix('$')), 1)
