如何刪除字符串中的最後一個SENTENCE，如果以某個字符結尾？

Question

這將是一件非常基本的事情，但我已經忘記了如何去做。我只想刪除列表中每個字符串的最後一行，如果它以'：'結尾。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) 

在一個打印時刻：

One more sentence 
One last sentence 

我現在該如何得到它，使它打印如下：

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

Answer 1

在這裏你去： -

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]) 
    } 
} 

Answer 2

不是很強大，但希望有一些東西g等你在正確的方向前進：

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) 

輸出
