Question

假设有这样的文字

class PopupButton: UIButton {
    override func awakeFromNib() {
        super.awakeFromNib()
        layer.borderWidth = 1.3
        layer.borderColor = Shared.instance.fadedTextColor.cgColor
        layer.cornerRadius = 10
        layer.backgroundColor = UIColor.white.cgColor
        setTitleColor(Shared.instance.textHeaderColor, for: .normal)
        NotificationCenter.default.addObserver(self, selector: #selector(colorChanged), name: NSNotification.Name(rawValue: "fadedTextColorChanged"), object: nil)
    }
    @objc func colorChanged(notification: Notification) {
        layer.borderColor = Shared.instance.fadedTextColor.cgColor
    }
}

按分隔符s = '\n\nPART I, WHERE I’M COMING FROM\n\n1\xa0My Call to Adventure: 1949–1967\n2\xa0Crossing the Threshold: 1967–1979\n3\xa0My Abyss: 1979–1982\n4\xa0My Road of Trials: 1983–1994\n5\xa0The Ultimate Boon: 1995–2010\n6\xa0Returning the Boon: 2011–2015\n7\xa0My Last Year and My Greatest Challenge: 2016–2017\n8\xa0Looking Back from a Higher Level\n\nPART II, LIFE PRINCIPLES\n\n1\xa0Embrace Reality and Deal with It\n2\xa0Use the 5-Step Process to Get What You Want Out of Life\n3\xa0Be Radically Open-Minded\n4\xa0Understand That People Are Wired Very Differently\n5\xa0Learn How to Make Decisions Effectively\nLife Principles: Putting It All Together\nSummary and Table of Life Principles\n\nPART III, WORK PRINCIPLES\n\nSummary and Table of Work Principles\nTO GET THE CULTURE RIGHT\n\nTO GET THE PEOPLE\n\nTO BUILD AND EVOLVE YOUR \nWork Principles: Putting It All Together\n\n'

拆分

PART

将前缀In [14]: parts = re.split(r'\n\nPART',s) In [15]: parts Out[15]: ['', ' I, WHERE I’M COMING FROM\n\n1\xa0My Call to Adventure: 1949–1967\n2\xa0Crossing the Threshold: 1967–1979\n3\xa0My Abyss: 1979–1982\n4\xa0My Road of Trials: 1983–1994\n5\xa0The Ultimate Boon: 1995–2010\n6\xa0Returning the Boon: 2011–2015\n7\xa0My Last Year and My Greatest Challenge: 2016–2017\n8\xa0Looking Back from a Higher Level', ' II, LIFE PRINCIPLES\n\n1\xa0Embrace Reality and Deal with It\n2\xa0Use the 5-Step Process to Get What You Want Out of Life\n3\xa0Be Radically Open-Minded\n4\xa0Understand That People Are Wired Very Differently\n5\xa0Learn How to Make Decisions Effectively\nLife Principles: Putting It All Together\nSummary and Table of Life Principles', ' III, WORK PRINCIPLES\n\nSummary and Table of Work Principles\nTO GET THE CULTURE RIGHT\n\nTO GET THE PEOPLE\n\nTO BUILD AND EVOLVE YOUR \nWork Principles: Putting It All Together\n\n']添加回列表

Part

我想一步完成它，

In [16]: ['PART '+ i for i in parts if i]
Out[16]:
['PART  I, WHERE I’M COMING FROM\n\n1\xa0My Call to Adventure: 1949–1967\n2\xa0Crossing the Threshold: 1967–1979\n3\xa0My Abyss: 1979–1982\n4\xa0My Road of Trials: 1983–1994\n5\xa0The Ultimate Boon: 1995–2010\n6\xa0Returning the Boon: 2011–2015\n7\xa0My Last Year and My Greatest Challenge: 2016–2017\n8\xa0Looking Back from a Higher Level',
 'PART  II, LIFE PRINCIPLES\n\n1\xa0Embrace Reality and Deal with It\n2\xa0Use the 5-Step Process to Get What You Want Out of Life\n3\xa0Be Radically Open-Minded\n4\xa0Understand That People Are Wired Very Differently\n5\xa0Learn How to Make Decisions Effectively\nLife Principles: Putting It All Together\nSummary and Table of Life Principles',
 'PART  III, WORK PRINCIPLES\n\nSummary and Table of Work Principles\nTO GET THE CULTURE RIGHT\n\nTO GET THE PEOPLE\n\nTO BUILD AND EVOLVE YOUR \nWork Principles: Putting It All Together\n\n']

如何完成这项任务？

Answer 1

尝试使用regex模块拆分正向前方以保留分隔符：

import regex
print regex.split(r"(?=\n\nPART)", s, flags=regex.VERSION1)

拆分文本而不删除分隔符
