Python：使用浮点数格式化字符串，右对齐

Question

I want to align a combination of str and float to the right side. In my example, "Tax = $" is a string and tax is a float. I have two ways to accomplish this.

print(("Tax = $%.2f" % tax).rjust(70))
print("%66s%.2f" % ("Tax = $",tax))

The output is the following:

                                                       Tax = $0.42

Both of them are working. But I don't think they are good enough. The codes are kind of burdensome. At the beginning, I wrote something like

print("Tax = $%.2f" % tax)

I tried to put a right align flag in this line, but I don't know where should I put it in.

Is there a neat way to do this?

Thank you,

Now with f-strings available in python 3.6 and newer, here is another way to look at it:

print(f"{(f'Tax = ${tax:.2f}'):>70}")

Using temporary variables:

rightSideStuff = f'Tax = ${tax:.2f}'
print(f"{rightSideStuff:>70}")
