好的,您可以按照以下步骤进行操作:
1. 导入所需模块
```python
import csv
```
2. 读取CSV文件并获取需要修改的列数据
```python
with open('example.csv', 'r') as file:
reader = csv.DictReader(file)
data = []
for row in reader:
if "万" in row['column_name']:
row['column_name'] = "0000"
data.append(row)
```
请将代码中的 `example.csv` 替换为您自己的CSV文件名,并将 `column_name` 替换为您需要修改的列的名称。
3. 将修改后的数据写入CSV文件
```python
with open('modified_data.csv', 'w', newline='') as file:
writer = csv.DictWriter(file, fieldnames=reader.fieldnames)
writer.writeheader()
for row in data:
writer.writerow(row)
```
请将代码中的 `modified_data.csv` 替换为您想要写入的CSV文件名。
完整代码如下:
```python
import csv
with open('example.csv', 'r') as file:
reader = csv.DictReader(file)
data = []
for row in reader:
if "万" in row['column_name']:
row['column_name'] = "0000"
data.append(row)
with open('modified_data.csv', 'w', newline='') as file:
writer = csv.DictWriter(file, fieldnames=reader.fieldnames)
writer.writeheader()
for row in data:
writer.writerow(row)
```
请注意替换文件名和列名以匹配您自己的CSV文件和需要修改的列名。
