以下是定义批处理方法的 Python 代码,批处理大小为 100:
```python
def batch_processing(data, batch_size=100):
"""
Batch processing data method with batch size specified
"""
# Calculate the number of batches
num_batches = len(data) // batch_size + int(len(data) % batch_size != 0)
# Batch processing
for i in range(num_batches):
start_idx = i * batch_size
end_idx = (i + 1) * batch_size
yield data[start_idx:end_idx]
```
使用方法:
```python
data = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
for batch_data in batch_processing(data, batch_size=3):
print(batch_data)
```
输出结果:
```
[1, 2, 3]
[4, 5, 6]
[7, 8, 9]
[10]
```
其中,`data` 是输入数据,`batch_size` 是批处理大小,`num_batches` 是数据分成的批数,`start_idx` 和 `end_idx` 是每个批次的起始和结束索引,`yield` 用于返回每个批次的数据。
