List list box and data conversion DataFrame

DataFrame →List

 

 

import numpy as np
import pandas as pd
test = pd.DataFrame({ 'IDCARD' :['ID1','ID1','ID1','ID2','ID2'],
                     'TIME' :['2019/11/21','2019/11/29','2019/11/30','2019/1/28','2019/2/13 ' ]}) 

Import numpy AS NP 
train_data = np.array (Test) # first data block into an array 
train_data_list train_data.tolist = ()   # followed by a list converted 
Print (np.array (train_data_list))   # break out easily see as an array

 

 Output:

 

 List→DataFrame

1 from pandas.core.frame import DataFrame
2 data_set = ['A','B','C']
3 data = DataFrame(data_set)  
4 #data = pd.DataFrame(data_set)
5 print(data)

Output:
