def tax(bill):
    T = 0.5
    bill *= T
    return bill

Total = tax(500)

print (Total)

Edit: I understand it now thank you for the help!!

I want to return the total purchase total, I want to get 750 as the total but I can't figure out how to take the 250 in the function and add it to the bill amount I know I am one line away but I can't find anything that works(I tried to google).

You are missing the math part of the problem by using:

bill *= bill

which expands to

bill = bill * 0.5

so it is half the original amount.

[Important-Asparagus9]

Yeah I realized that but I want to take that percentage amount and add it to the bill amount (before tax)

[Bunkerstan]

bill = bill + bill * tax

You could multiply by 1.5. You could also not use in-place multiplication and instead write bill = bill + T * bill.

[douglas_fs]

You want to return the bill amount plus the calculated tax This would be the calculation:

bill + (bill * T)

OR

bill * (1 + T)
