将 Python 字符串格式化与列表一起使用

I construct a string s in Python 2.6.5 which will have a varying number of %s tokens, which match the number of entries in list x. I need to write out a formatted string. The following doesn't work, but indicates what I'm trying to do. In this example, there are three %s tokens and the list has three entries.

s = '%s BLAH %s FOO %s BAR'
x = ['1', '2', '3']
print s % (x)

我希望输出字符串是:

1 BLAH 2 FOO 3 BAR

推荐答案

print s % tuple(x)

而不是

print s % (x)
