StringDefinedSplitStringGetLastElementOutputResult 状态图解释 StringDefined:定义一个字符串。 SplitString:使用str.split()方法对字符串进行分割。 GetLastElement:获取分割后列表中的最后一个元素。 OutputResult:输出最终结果。 结论 通过使用Python 3中的str.split()方法,我们可以轻松地分割字符串并获取最后一个元素。

, where −1 is the last element in a string, −2 is the second last, and so on. We can only use the integer number type for indexing; otherwise, the TypeError will be raised. Example: String1 = ‘intellipaat’ print (String1) print (String1[0]) print (String1[1]) print (...
Therefore, the string that might have been left after the nth occurrence of the substring is stored as the last element of the sep variable. Therefore, we subtract the length of the original string s with the length of the last string present in the sep variable, which is accessed as ...
Or if I wanted to access say the first or the last element of that string,I can use my common generic sequence operations. 我也会做切片。 I can also do slicing. 所以我可能想从字符串的最开始开始,取前三个对象。 So I might want to start from the very beginning of the string and take...
