Question

尝试通过pep8重新计算代码。

代码：

    print """Exception when sending email to: {0},
        from: {1}, subject: {2}, e: {3}""".format(to, fr, subject, e)

输出：

Exception when sending email to: to,
                from: fr, subject: subject, e: Invalid URL 'http//127.0.0.1:8000/'

如何删除上述输出中from之前的空格？感谢

更新

以下代码正常运行。我应该删除这篇文章吗？

 34             print ($
 35                 "Exception when sending email to: {0},"$
 36                 "from: {1}, subject: {2}, e: {3}").format(to, fr, subject, e)$

Answer 1

由于您使用的是"""，因此您应该在this link搜索“triple-quotes”一词。

更改：

print """Exception when sending email to: {0}, from: {1}, subject: {2}, e: {3}""".format(to, fr, subject, e)

要

print """Exception when sending email to: {0}, from: {1}, subject: {2}, e: {3}""".format(to, fr, subject, e)

修改

如果您需要缩短线条，还可以使用\继续多行声明：

<强>代码：

print("""Exception when sending email \ to: {0}, \ from: {1}, \ subject: {2}, \ e: {3}""".format('to', 'fr', 'subject', 'e'))

<强>输出：

Exception when sending email to: to, from: fr, subject: subject, e: e

Python：多行格式输出中的空格
