我有以下代码

test = "have it break."
selectiveEscape = "Print percent % in sentence and not %s" % test

print(selectiveEscape)

我想获得输出:

Print percent % in sentence and not have it break.

实际发生了什么:

    selectiveEscape = "Use percent % in sentence and not %s" % test
TypeError: %d format: a number is required, not str

我正在尝试使用lazy参数构建一个格式字符串,例如我需要像:

"%s \%s %s" % ('foo', 'bar') # "foo %s bar"

我怎样才能做到这一点？
