我有以下代码
test = "have it break."
selectiveEscape = "Print percent % in sentence and not %s" % test
print(selectiveEscape)
我想得到输出：
Print percent % in sentence and not have it break.
实际发生的情况：
selectiveEscape = "Use percent % in sentence and not %s" % test
TypeError: %d format: a number is required, not str
>>> test = "have it break."
>>> selectiveEscape = "Print percent %% in sentence and not %s" % test
>>> print selectiveEscape
Print percent % in sentence and not have it break.
