The list numpy dataframe and mutual conversion, set differencing

Title by nparray dataframe data can be converted to the list, then the intersection of difference sets, etc.

import pandas as pd
import numpy as np

jjrmember = pd.read_excel('jjr_member_26.xlsx')

kfmember = pd.read_excel('kf_member_26.xlsx')

jjr = np.array(jjrmember['id'])
kf = np.array(kfmember['id'])

listjjr = jjr.tolist()
listkf = kf.tolist()

s = list(set(listjjr)-set(listkf))# 求差集 需要转为list
snp = np.array(s)# 通过nparray将list转dataframe
df = pd.DataFrame(snp)

df.to_excel('ids.xlsx', sheet_name='Sheet1')
