pythoninc用一个空格替换多个新行和一个新行的方法是什么？

Question

我有一个字符串：

"2\nOur\nstrategy drives \nsustainably higher profits and margins\n\nStrengthening our hubs is a critical foundation to maximize profitability\n\nDriving revenue improvements from all areas of business\n\nImproving efficiency and productivity \n\nGreater accountability and transparency\n"

输出应为：

"2 Our strategy drives sustainably higher profits and margins\nStrengthening our hubs is a critical foundation to maximize profitability\nDriving revenue improvements from all areas of business\nImproving efficiency and productivity \nGreater accountability and transparency "

Answer 1

一种脓性溶液：

'\n'.join(e.replace('\n', ' ') for e in s.split('\n\n'))

首先，拆分出现'\n\n'的字符串，然后用'\n'替换列表中每个元素中的' '，最后，用'\n'连接所有内容。你知道吗

另一种解决方案

我将使用一个临时辅助字符串，它允许我临时替换双新行，然后用空格替换单新行，然后用新行替换临时辅助字符串：

假设您的字符串是s：

s = "2\nOur\nstrategy drives \nsustainably higher profits and margins\n\nStrengthening our hubs is a critical foundation to maximize profitability\n\nDriving revenue improvements from all areas of business\n\nImproving efficiency and productivity \n\nGreater accountability and transparency\n"

temp = '-\t-'
s = s.replace('\n\n', temp).replace('\n', ' ').replace(temp, '\n')
