<think>我们需要调整代码以满足以下两个要求：
1. 股票代码搜索范围锁定在给定的列表（而不是从akshare获取所有A股股票代码）。
2. 调整批处理：每次处理20~30只股票，每隔20~30秒请求一次。
具体修改步骤：
1. 不再调用`get_all_stock_codes`函数来获取全部股票代码，而是使用用户提供的股票代码列表。
2. 将用户提供的股票代码字符串转换为列表（注意：原字符串中股票代码以空格或换行分隔，我们将其分割成列表）。
3. 调整`main`函数，使其接受一个股票代码列表，并修改批处理的大小为20~30（这里我们可以取一个中间值，比如25，或者随机在20~30之间选择，但为了简单，我们可以固定为25，也可以让调用者指定范围）。
4. 在批处理之间等待20~30秒（同样，我们可以固定为25秒，或者随机，这里我们固定为25秒，也可以让调用者指定）。
但是，为了更灵活，我们可以修改`main`函数的参数，允许指定批处理大小和间隔时间的范围，并随机选择。但原要求是20~30，我们可以设定批处理大小为25，间隔25秒。或者，我们可以每次随机在20~30之间取一个数。
考虑到原代码中已经支持指定`batch_size`和`interval`，我们只需要在调用`main`函数时传入合适的值即可。
然而，用户要求是“每隔20~30秒请求一次，每一次批处理20~30只股票”，我们可以这样实现：
- 在每一批处理前，随机生成该批的大小（在20到30之间）和间隔时间（在20到30秒之间），但这样会导致每一批的大小和间隔都不同。
- 或者，我们固定批大小为25，间隔25秒。
为了严格符合要求（20~30），我们可以使用随机数。但注意，原代码中批处理是固定大小，这里我们修改为每一批随机在20~30之间。
但是，原代码中批处理是连续的，如果随机批大小，可能最后一批不够。所以，我们可以这样：
- 在循环中，每次随机生成一个批大小（在20到30之间），然后取这个批大小的股票进行处理，直到处理完所有股票。
修改`main`函数中的循环部分，每次循环时随机生成一个批大小（在20到30之间），然后从股票列表中取出这个数量的股票（如果剩余不足，则取剩余全部）。
另外，我们不再需要获取所有A股股票代码，而是使用给定的列表。
步骤：
1. 将提供的股票代码字符串转换为列表（注意去除空行和空格）。
2. 修改`main`函数，使其接受一个股票代码列表作为参数（而不是在函数内部获取）。
3. 在循环中，每次随机生成批大小（在20~30之间）和间隔时间（在20~30秒之间，但注意间隔时间只在不是最后一批时等待）。
但是，为了保持代码清晰，我们也可以不随机，而是固定为25。这里按照要求，我们使用随机。
我们将修改`main`函数如下：
- 去掉`get_all_stock_codes`的调用，改为从参数传入股票代码列表。
- 在循环中，每次随机生成`current_batch_size`（在20到30之间，包括20和30），然后处理`current_batch_size`只股票。
- 同样，随机生成当前批次处理后的等待时间`current_interval`（在20到30秒之间）。
注意：随机数生成使用`random.randint(20,30)`。
因此，我们需要导入`random`模块。
修改后的代码结构：
```python
import random
# ... 其他导入 ...
def main(stock_codes, min_batch=20, max_batch=30, min_interval=20, max_interval=30):
# 如果stock_codes为空，则退出
if not stock_codes:
print("股票代码列表为空，程序退出")
return
total_count = len(stock_codes)
print(f"共获取到 {total_count} 只股票，开始筛选...")
result = []
i = 0
while i < total_count:
# 随机生成当前批次的股票数量
current_batch_size = random.randint(min_batch, max_batch)
# 如果剩余股票数量不足current_batch_size，则取剩余全部
if i + current_batch_size > total_count:
current_batch_size = total_count - i
batch = stock_codes[i:i+current_batch_size]
print(f"\n处理第 {i//current_batch_size + 1} 批，共 {len(batch)} 只股票")
for code in tqdm(batch, desc="处理中"):
# 特殊处理CDR股票（这里保留原代码的跳过逻辑）
if code.startswith('sh689'):
continue
stock_df = get_stock_data(code)
if stock_df is None:
continue
if check_condition(stock_df):
result.append(code)
print(f"\n符合条件的股票：{code}")
# 更新索引
i += current_batch_size
# 如果不是最后一批，则等待随机时间
if i < total_count:
current_interval = random.randint(min_interval, max_interval)
print(f"本批次处理完成，等待 {current_interval} 秒后继续下一批...")
time.sleep(current_interval)
# ... 输出结果 ...
if __name__ == "__main__":
# 给定的股票代码字符串（这里用变量stock_list_str表示）
stock_list_str = """000001.SZ
000002.SZ
... (省略) ...
603986.SH"""
# 将字符串分割成列表，去除空行和空格
stock_codes_list = [code.strip() for code in stock_list_str.splitlines() if code.strip()]
# 调用main函数，传入股票代码列表，并指定批处理大小和间隔时间的范围（20~30）
main(stock_codes=stock_codes_list, min_batch=20, max_batch=30, min_interval=20, max_interval=30)
```
注意：原代码中有一个小错误，在股票代码列表中有一个股票代码是“60606.SH”，这可能是笔误，但为了保持原样，我们不做修改。
另外，原代码中在获取股票数据时，使用了`ak.stock_zh_a_daily`，注意这个函数需要传入的股票代码是不带后缀的，还是带后缀的？原代码中获取的股票代码是带后缀的（如'000001.SZ'），而`ak.stock_zh_a_daily`函数可能需要不带后缀的代码，或者需要带市场前缀（如'sh'或'sz'）？这需要根据akshare的文档来确定。
但是，原代码中已经处理了CDR股票（跳过），并且原代码在获取所有A股股票代码时返回的是带后缀的代码（如'000001.SZ'），所以我们在获取数据时，需要将代码转换为akshare要求的格式。
查看原`get_stock_data`函数，它直接传入`symbol=code`，而code是带后缀的（如'000001.SZ'）。那么，我们需要检查akshare的`stock_zh_a_daily`函数是否支持带后缀的代码。
根据akshare文档，该函数要求股票代码是带市场前缀的，例如：`symbol="sh000001"`。但是，我们的代码是'000001.SZ'，所以需要转换。
转换方式：将后缀转换为小写，然后将代码中的点去掉，例如'000001.SZ' -> 'sz000001'。但是，原代码中并没有做这个转换，所以原代码可能无法正确获取数据。
因此，我们需要在`get_stock_data`函数中做转换：
- 将`code`转换为akshare需要的格式：去掉点，并将后缀改为小写，然后组合成市场前缀+代码数字（注意：代码数字部分可能不需要前面的0，但akshare的示例是6位数字）。
但是，原代码中获取所有A股股票代码时返回的格式是带后缀的，并且原代码中直接使用这个带后缀的代码去调用`stock_zh_a_daily`，这可能是错误的。所以我们需要修正。
修正方法：
- 在`get_stock_data`函数中，将传入的`code`（如'000001.SZ'）转换为`symbol="sz000001"`。
转换代码：
```python
# 将code分割，去掉后缀的点，然后组合成市场前缀+股票代码
# 例如：'000001.SZ' -> 'sz000001'
if '.' in code:
code_num, exchange_suffix = code.split('.')
exchange_prefix = exchange_suffix.lower() # 'sz' or 'sh'
akshare_symbol = exchange_prefix + code_num
else:
# 如果没有后缀，则尝试使用原代码，但可能出错
akshare_symbol = code
```
然后，在调用`ak.stock_zh_a_daily`时，传入这个`akshare_symbol`。
但是，原代码中并没有做这个转换，所以原代码可能无法正确获取数据。因此，我们建议在`get_stock_data`函数中加入这个转换。
由于原问题主要是调整股票代码列表和批处理，我们这里先按照用户要求调整主函数，然后修正数据获取的代码转换问题。
所以，我们修改`get_stock_data`函数，将股票代码转换为akshare要求的格式。
修改后的`get_stock_data`函数：
```python
def get_stock_data(symbol, days=60):
"""获取股票指定天数的历史数据"""
try:
# 转换股票代码格式：从'000001.SZ' 到 'sz000001'
if '.' in symbol:
code_num, exchange_suffix = symbol.split('.')
exchange_prefix = exchange_suffix.lower()
akshare_symbol = exchange_prefix + code_num
else:
akshare_symbol = symbol
# 计算日期
end_date = datetime.datetime.now().strftime("%Y%m%d")
start_date = (datetime.datetime.now() - datetime.timedelta(days=days+30)).strftime("%Y%m%d")
# 使用转换后的股票代码获取数据
stock_df = ak.stock_zh_a_daily(
symbol=akshare_symbol,
start_date=start_date,
end_date=end_date,
adjust="qfq"
)
# 如果返回的数据为空，则返回None
if stock_df is None or stock_df.empty:
return None
# 确保数据按日期排序
stock_df['date'] = pd.to_datetime(stock_df['date'])
stock_df = stock_df.sort_values('date')
return stock_df
except Exception as e:
print(f"获取股票 {symbol} 数据失败: {e}")
return None
```
这样，我们就修正了股票代码格式的问题。
综上所述，我们修改了以下部分：
1. 使用给定的股票代码列表，而不是从akshare获取。
2. 修改了`main`函数，使其接受股票代码列表，并在批处理时使用随机批次大小（20~30）和随机间隔时间（20~30秒）。
3. 修正了`get_stock_data`函数中股票代码格式转换的问题。
注意：原代码中还有一处小错误，在股票代码列表中有一个股票代码是“028.SZ”，这可能是“002028.SZ”的笔误？但为了保持原样，我们不做修改。如果这个代码在转换后变成'sz028'，而akshare可能需要6位代码，可能会出错。所以，在转换时，我们可能需要将代码数字部分补足6位？但原akshare的示例代码中，沪市是6位（如600000），深市也是6位（如000001）。所以，对于不足6位的，我们前面补0。
因此，在转换时，我们将数字部分补足6位：
```python
code_num = code_num.zfill(6)
akshare_symbol = exchange_prefix + code_num
```
修改`get_stock_data`函数中的转换部分：
```python
if '.' in symbol:
code_num, exchange_suffix = symbol.split('.')
# 补足6位
code_num = code_num.zfill(6)
exchange_prefix = exchange_suffix.lower()
akshare_symbol = exchange_prefix + code_num
else:
# 如果原代码没有点，则尝试补足6位？但不知道市场，所以不处理
akshare_symbol = symbol
# 这里也可以尝试补足6位，但可能没有市场信息，所以先这样
```
这样，像'028.SZ'会被转换为'sz000028'，而'600000.SH'会被转换为'sh600000'，符合akshare要求。
最后，我们给出完整的修改后代码。
注意：由于给定的股票代码列表很长，我们在代码中用一个变量`stock_list_str`存储，但为了简洁，这里只显示部分。

### 主要修改说明：
1. **股票代码范围锁定**：
- 创建了常量 `STOCK_LIST` 存储您提供的所有股票代码
- 移除了原 `get_all_stock_codes()` 函数，直接使用预定义列表
2. **批处理参数调整**：
- 使用 `random.randint(20, 30)` 随机确定每批处理的股票数量（20-30只）
- 同样使用随机数确定请求间隔时间（20-30秒）
- 每批处理完成后自动休眠指定时间
3. **股票代码格式转换**：
- 添加了代码格式转换逻辑（`000001.SZ` → `sz000001`）
- 确保与akshare接口要求的格式匹配
4. **错误处理优化**：
- 增强数据获取时的异常处理
- 添加空数据检查（`if stock_df is not None and not stock_df.empty`）
5. **去除了不必要的参数**：
- `main()` 函数不再需要参数
- 批次大小和间隔时间在函数内部随机生成
### 使用说明：
1. 程序会随机选择20-30只股票作为一批进行处理
2. 每批处理完成后会随机等待20-30秒
3. 处理进度通过`tqdm`进度条直观显示
4. 符合条件的股票会实时打印出来
5. 最终输出所有符合条件的股票列表
### 注意事项：
1. 确保已安装所需库：`pip install akshare pandas tqdm`
2. 股票数据获取可能受网络状况影响
3. 如需调整随机范围，可修改`random.randint(20, 30)`中的参数
