Question

我从文件中读取以下行

# subject, catagory, note
literature,general education,,note: see approved list
social-cultural elective,general education,,note: see approved

我想拆分这些以便稍后添加到字典中。所以我想分开逗号，双逗号和“：”字符。我将如何做到这一点，以便最终结果显示为

{'Literature' : [['general education'],[ 'see approved list']] 'social-cultural elective' : [['general education'],[see approved]]}

即时通讯使用重新拆分并具有“W +”表达但由于每行都有不同的空格和其他字符，例如“ - ”，帮助

Answer 1

使用Python内置split函数：

>>> a_str='social-cultural elective,general education,,note: see approved '
>>> import re
>>> re.split(': |, |\*|\n', a_str)

PS：对于双逗号，您可以先执行 str.replace

Answer 2

试试这个：

import re
splitter = re.compile(r":|,,?")
for line in ("literature,general education,,note: see approved list",
             "social-cultural elective,general education,,note: see approved"):
    print splitter.split(line)

打印：

['literature', 'general education', 'note', ' see approved list']
['social-cultural elective', 'general education', 'note', ' see approved']

如果这不完全是你想要的，请编辑你的问题，因为这正是你所要求的;-)（即“所以我想用逗号分隔，双逗号和”：“字符”）。
