Python：多行格式输出中的空格

试图通过pep8重新计算代码的系数

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/'

如何从上述输出中的中删除

之前的空格？谢谢

更新

以下代码工作正常。我应该删除这个帖子吗

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

由于您使用的是
“”“
，因此应在以下位置搜索术语“三重引号”

更改：

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

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

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

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

至：

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

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

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

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

编辑：

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

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

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

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

如果需要保持行短，还可以使用
\
继续多行语句：

代码：

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

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

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

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

输出：

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

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