铸造原始字符串python [英] casting raw strings python

问题描述

给定一个包含字符串的变量，是否有一种快速的方法可以将其转换为另一个原始字符串变量?

Given a variable which holds a string is there a quick way to cast that into another raw string variable?

以下代码应该说明我所追求的:

The following code should illustrate what I'm after:

line1 = "hurr..\n..durr"
line2 = r"hurr..\n..durr"

print(line1 == line2)  # outputs False
print(("%r"%line1)[1:-1] == line2)  # outputs True

到目前为止我发现的最接近的是 %r 格式化标志，它似乎返回原始字符串，尽管在单引号内.有没有更简单的方法来做这种事情?

The closest I have found so far is the %r formatting flag which seems to return a raw string albeit within single quote marks. Is there any easier way to do this kind of thing?

推荐答案

Python 3:

"hurr..\n..durr".encode('unicode-escape').decode()

Python 2:

"hurr..\n..durr".encode('string-escape')
