Question

这将是一个非常基本的东西，但我忘记了如何做到这一点。我只想删除列表中每个字符串的最后一行，如果它以＆＃39;：＆＃39;结尾。我有

desc1 = ['A sentence. Another sentence', 'One more sentence. A sentence that finishes with:', 'One last sentence. This also finishes with a:']
for string in desc1:
    if string.endswith(':'):
        a = string.split('.')
        b = a[:-1]
        c = '.'.join(map(str, b))
        print (c)

目前打印：

One more sentence
One last sentence

我现在如何获取它以便打印以下内容：

['A sentence. Another sentence', 'One more sentence.', 'One last sentence.']

Answer 1

不是非常强大，但希望能让你朝着正确的方向前进：

strings = ['A sentence. Another sentence', 'One more sentence. A sentence that finishes with:', 'One last sentence. This also finishes with a:']

new_strings = []

for string in strings:
    if string.endswith(':'):
                sentences = string.split('.')
                string = '.'.join(sentences[:-1]) + '.'

    new_strings.append(string)

print(new_strings)

<强>输出

['A sentence. Another sentence', 'One more sentence.', 'One last sentence.']

在这里： -

var descFinal = [];
for(var i=0; i< desc1.length; i++){
  if(desc1[i].endsWith(":")){
   descFinal.push(desc1[i].substring(0, desc1[i].lastIndexOf('.') + 1));
  }else{
    descFinal.push(desc1[i])
  }
}

如果以某个字符结尾，如何删除字符串中的最后一个SENTENCE？
