python基于模式拆分长输出字符串(无分隔符)

def split_string_by_pattern(string, pattern):
    result = []
    start = 0
    while True:
        index = string.find(pattern, start)
        if index == -1:
            result.append(string[start:])
            break
        result.append(string[start:index])
        start = index + len(pattern)
    return result

output_string = "This is a long output string without any separator. It needs to be split based on a pattern."
pattern = "output"

result = split_string_by_pattern(output_string, pattern)
print(result)

['This is a long ', ' string without any separator. It needs to be split based on a pattern.']
