以下是生成的Python代码,可以读取CSV文件中的violation字符并按照相同内容进行分类,并根据line数值进行排序:
```python
import csv
# 读取CSV文件中的数据
with open('data.csv', 'r') as file:
reader = csv.DictReader(file)
data = [row for row in reader]
# 根据violation字符进行分类
violation_dict = {}
for row in data:
if row['violation'] not in violation_dict:
violation_dict[row['violation']] = []
violation_dict[row['violation']].append(row)
# 根据line数值进行排序
for violation in violation_dict:
violation_dict[violation] = sorted(violation_dict[violation], key=lambda x: int(x['line']))
# 输出分类和排序后的结果
for violation in violation_dict:
print(violation)
for row in violation_dict[violation]:
print(row)
```
其中,`data.csv`为包含数据的CSV文件,文件中应该包含`violation`和`line`两列数据。程序首先读取文件中的数据,并按照`violation`字符进行分类,将相同的内容放在同一个列表中。然后对于每个分类,根据`line`数值进行排序,最后输出分类和排序后的结果。
