pandas函数汇总,来下载
错误提示显示 NameError: name 's' is not defined,说明 s 变量未定义。因此,需要将 s 从 read_csv() 函数中删除。下面是正确的代码:
```python
import pandas as pd
download = pd.read_csv('E:/pyjupthon/使用pandaas进行数据预处理/user_all_info.csv', index_col=0, encoding='utf-8', engine='python')
# 定义去重函数
def del_rep(list1):
list2 = [] # 定义一个空列表
for i in list1:
if i not in list2:
list2.append(i)
return list2
# 将下载意愿从数据框提取出来
download = list(download['是否愿意下载'])
print('去重前下载意愿选项总数为:', len(download))
download_rep = del_rep(download) # 使用自定义的函数去重
print('使用方法一去重后下载意愿选项总数为:', len(download_rep))
print('用户选项为:', download_rep)
```
