如何在python中将浮点数格式化为字符串?

def main():
    M = float(input('Please enter sales for Monday: '))
    T = float(input('Please enter sales for Tuesday: '))
    W = float(input('Please enter sales for Wednesday: '))
    R = float(input('Please enter sales for Thursday: '))
    F = float(input('Please enter sales for Friday: '))
    sales = [M, T, W, R, F]

        total = 0 

    for value in sales:
        total += value

    print ('The total sales for the week are: $',total('.2f'))

main()

使用 .2f 格式时，我收到此异常:

With the .2f format I am getting this exception:

TypeError: 'float' object is not callable

如果我删除 .2f 脚本运行正常，但格式不是我想要的，它显示为:

If I remove the .2f the script runs properly but the formatting is not how I would like it, it displays as:

The total sales for the week are: $ 2500.0

我希望它有 2 个小数位并且 $ 符号之间没有空格.

I would prefer to have it so that there are 2 decimal places and no space between the $ sign.
