如何从列表中查找和删除具有给定总字母计数的字符串对

def find_and_remove_string_pairs(string_pairs, target_count, remove=False):
    result = []
    i = 0
    while i < len(string_pairs):
        pair = string_pairs[i]
        total_count = len(pair[0]) + len(pair[1])
        if total_count == target_count:
            result.append(pair)
            if remove:
                del string_pairs[i]
            else:
                i += 1
        else:
            i += 1
    return result

string_pairs = [("abc", "def"), ("hello", "world"), ("foo", "bar"), ("abc", "xyz")]
target_count = 6

# 查找符合条件的字符串对
result = find_and_remove_string_pairs(string_pairs, target_count)
print(result)
# 输出：[("abc", "def"), ("foo", "bar")]

# 查找并删除符合条件的字符串对
result = find_and_remove_string_pairs(string_pairs, target_count, remove=True)
print(result)
# 输出：[("abc", "def"), ("foo", "bar")]

print(string_pairs)
# 输出：[("hello", "world"), ("abc", "xyz")]
