可以使用 pandas 库中的 read_csv() 函数来读取 csv 文件,并通过 dropna() 和 drop_duplicates() 函数删除 NA 值和重复值,再使用 reset_index() 函数重置索引列。
以下是代码示例:
```python
import pandas as pd
# 读取 csv 文件
df = pd.read_csv('step2/message.csv')
# 删除 NA 值和重复值
df = df.dropna().drop_duplicates()
# 重置索引列
df = df.reset_index(drop=True)
# 输出结果
print(df)
```
输出结果如下:
```
