返回要馈送到 string.format() 的参数元组 [英] Return a tuple of arguments to be fed to string.format()

问题描述

目前，我正在尝试在 Python 中获取一个方法来返回零、一个或两个字符串的列表以插入字符串格式化程序，然后将它们传递给字符串方法.我的代码看起来像这样:

Currently, I'm trying to get a method in Python to return a list of zero, one, or two strings to plug into a string formatter, and then pass them to the string method. My code looks something like this:

class PairEvaluator(HandEvaluator):
  def returnArbitrary(self):
    return ('ace', 'king')

pe = PairEvaluator()
cards = pe.returnArbitrary()
print('Two pair, {0}s and {1}s'.format(cards))

当我尝试运行这段代码时，编译器给出了一个 IndexError: tuple index out of range.
我应该如何构造返回值以将其作为参数传递给 .format()?

When I try to run this code, the compiler gives an IndexError: tuple index out of range.
How should I structure my return value to pass it as an argument to .format()?

推荐答案

print('Two pair, {0}s and {1}s'.format(*cards))

你只缺了星星 :D
