Question

如何在下一行打印这些语句？我试过\ n但是输出显示\ n而不是在下一行打印语句。我希望使用格式化程序。代码是：

formatter = "%r %r %r %r"

print formatter  %(
"I had this thing.\n",
    "That you could type up right.\n ",
    "But it didn't sing.\n",
     "So I said goodnight."
    )

Answer 1

它正在使用%s或%r：

formatter = "%s %s %s %s"

print formatter  %(
"I had this thing.\n",
    "That you could type up right.\n ",
    "But it didn't sing.\n",
     "So I said goodnight."
    )

%r使用repr method，而不会形成特殊字符：

print(repr('\ntext'))
>>> '\ntext'

print(str('\ntext'))
>>>
text

如果您需要保留某些行的原始字符串，则应将formater更改为此模式，并在需要时使用r"rawstrings with special characters"+'\n'添加换行符。

formatter = "{}{}{}{}"

print(formatter.format(
    r"C:\n"+'\n',
    "That you could type up right.\n",
    "But it didn't sing.",
     "So I said goodnight."
    ))

# >>>C:\n
# That you could type up right.
# But it didn't sing.So I said goodnight.    

print(formatter.format(
    1,2,3,4)
    )        
# >>> 1234

在下一行中打印语句
