在Python中有没有编写多行字符串的干净方法？[副本]

Question

def useless_func():
    # WRONG WAY A : string_A displays well but breaks the 80 char max PEP 8 recommandation
    string_A = "Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua."

    # WRONG WAY B : string_B will create unwanted spaces between word 'sed' and 'do' when printed
    string_B = "Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed\
        do eiusmod tempor incididunt ut labore et dolore magna aliqua."

    # WRONG WAY C : string_C displays well  but makes my code ugly because it breaks indentation
    string_C = "Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed\
do eiusmod tempor incididunt ut labore et dolore magna aliqua."

    # WRONG WAY D : string_D (triples quotes) has the same problem than string_B (unwanted spaces)
    string_D = '''Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed
        do eiusmod tempor incididunt ut labore et dolore magna aliqua.'''

Answer 1

我会去：

def pr():
    # parentheses are for grouping and (as a bonus) for a pretty indentation
    s = ("aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"
         "bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb")
    print s

引用Python的非正式介绍：

两个相邻的字符串字元自动串联；上面的第一行也可以写成word='help''a'；这只适用于两个文本，而不适用任意字符串表达式。

>>> s = 'a' 'b'
>>> s
'ab'
>>> s = 'a''b' # space is not necessary
>>> s
'ab'

>>> import dis
>>> dis.dis(pr)

 0 LOAD_CONST               1 ('aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaabbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb')

// prints "hello world"
#include <stdio.h>

int main(int argc, char **argv) {
  printf("hello" " world");
  return 0;
}
