如何在Python字符串中有选择地转义百分比（％）？

Question

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.

实际发生的情况：

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

Answer 1

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