python 将语句拆分为多行

Question

我有以下代码:

print "my name is [%s], I like [%s] and I ask question on [%s]" % ("xxx", "python", "stackoverflow")

我想将这一长行分成多行:

print
  "my name is [%s]"
  ", I like [%s] "
  "and I ask question on [%s]"
  % ("xxx", "python", "stackoverflow")

能否提供正确的语法？

Answer 1

通过将所有内容放在括号内来使用隐含的行继续。这是Python's Style Guide (PEP 8)中推荐的方法:

print ("my name is [%s]"
       ", I like [%s] "
       "and I ask question on [%s]"
       % ("xxx", "python", "stackoverflow"))

这是可行的，因为 Python 解释器将连接相邻的字符串文字，所以 "foo"'bar' 变成了 'foobar'。
