在Jupyter Notebook中获取过去六个月的出货数据,并排除包含当月的数据,通常涉及Pandas库,它是一个强大的数据分析工具。假设你有一个名为`sales_data.csv`的CSV文件,其中包含日期列`date`和出货量列`shipments`。你可以按照以下步骤操作:
1. **导入所需库**:
```python
import pandas as pd
from datetime import timedelta, datetime
```
2. **加载数据**:
```python
sales_df = pd.read_csv('sales_data.csv')
```
3. **转换日期列** (如果需要):
```python
sales_df['date'] = pd.to_datetime(sales_df['date'])
```
4. **计算六个月前的截止日期**:
```python
six_months_ago = datetime.now() - timedelta(days=6*30)
```
5. **过滤出六个月前的数据(不包括当前月份)**:
```python
mask = (sales_df['date'] > six_months_ago) & (sales_df['date'] < datetime.now().replace(day=1)) # 确保排除当月第一天的数据
past_sales = sales_df.loc[mask]
```
6. **查看结果**:
```python
print(past_sales)
```
请注意,这个例子假设`date`列是以完整的日期形式存储的,如果不是,你需要调整日期处理部分。此外,这里我们简单地排除了当月的第一天,如果你有其他日期范围需求,可能需要进一步调整。
