下面是一个使用rsplit()方法查找最后一次出现位置的示例代码: text="Hello World! Hello Python!"substring="Hello"split_list=text.rsplit(substring,1)last_occurrence=len(text)-len(split_list[-1])-len(substring)print("The last occurrence of '{0}' is at position {1}".format(substring,last_occur...
Split string on last delimiter occurrence. Write a Python program to split a string on the last occurrence of the delimiter. Sample Solution: Python Code: # Define a string 'str1' containing a comma-separated list of characters.str1="w,3,r,e,s,o,u,r,c,e"# Split the string 'str1'...

>>> text = 'yeah, but no, but yeah, but no, but yeah' >>> # Exact match >>> text == 'yeah' False >>> # Match at start or end >>> text.startswith('yeah') True >>> text.endswith('no') False >>> # Search for the location of the first occurrence >>> text.find('no...
Split the string at the last occurrence of sep, and return a 3-tuple containing the part before the separator, the separator itself, and the part after the separator. If the separator is not found, return a 3-tuple containing two empty strings, followed by the string itself. ...
>>> line.rsplit("|", maxsplit=1) ['Rubber duck|5', '10'] This splits from the right-hand side of the string. Or you can think of it as a reverse split, splitting from the end of the string.So here we're splitting on the last occurrence of the pipe character....

If any class was duplicated in this search, all but the last occurrence would be deleted from the MRO list. So, for our earlier example, the search order would be D, B, C, A (as opposed to D, B, A, C, A with classic classes)....
