如何字符串替换数组中的符号并拆分？

def replace_and_split(arr, symbol, delimiter):
    new_arr = []
    for string in arr:
        replaced_string = string.replace(symbol, delimiter)
        split_string = replaced_string.split(delimiter)
        new_arr.extend(split_string)
    return new_arr

# 示例用法
arr = ["apple,banana,orange", "grape;watermelon;kiwi", "pear|pineapple|mango"]
symbol = ","
delimiter = " "
result = replace_and_split(arr, symbol, delimiter)
print(result)

['apple', 'banana', 'orange', 'grape', 'watermelon', 'kiwi', 'pear', 'pineapple', 'mango']
