在python中包装行：断开参数字符串

我有一个脚本,其中一个很长的str类型的参数传递给一个函数：

parser = argparse.ArgumentParser(description='Auto-segments a text based on the TANGO algorithm (Rie Kubota Ando and Lillian Lee, "Mostly-Unsupervised Statistical Segmentation of Japanese Kanji Sequences" (Natural Language Engineering, 9(2):127-149, 2003)).')

我想将此脚本中的行长限制为79个字符,这意味着在所讨论字符串的中间出现断行.仅在79处换行就可以产生如下语法错误的语法：

parser = argparse.ArgumentParser(description="Auto-segments a text based on 
    the TANGO algorithm (Rie Kubota Ando and Lillian Lee, 'Mostly-Unsupervis
    ed Statistical Segmentation of Japanese Kanji Sequences' (Natural Langua
    ge Engineering, 9(2):127-149, 2003)).")

PEP 8有在各种非参数字符串内部位置处换行的准则,但是有没有办法在参数字符串中间来换行？

(相关但不太重要的问题：在(python)脚本中打破自然语言文本中间词的明智/传统方式是什么？)

解决方法:

文字字符串可以彼此相邻出现,并且可以编译为单个字符串.从而：

parser = argparse.ArgumentParser(description="Auto-segments a text based on "
    "the TANGO algorithm (Rie Kubota Ando and Lillian Lee, 'Mostly-Unsupervised "
    "Statistical Segmentation of Japanese Kanji Sequences' (Natural Language "
    "Engineering, 9(2):127-149, 2003)).")

根据需要进行调整以适合80.
