It depends on your use case. In which format you want to retrieve your dataset. According to your example, you can try something as given below.
import pandas as pd
data = pd.read_csv('data.txt.txt',header=None)
data = data.applymap(lambda x: str(x.replace(' ',',')))
data = data.str.split(',',expand=True)
df1 = data.iloc[:,2:5]
df2 = data.iloc[:,5:8]
df3 = data.iloc[:,8:11]
objs = [df1,df2,df3]
You have to create some python code according to your use case.
Hope this will give you some idea.
