Pandas not working in python3 but works in python

Question

I tried to run pandas in python3 . But I get the following error.

user@client3:~/smith/Python$ python3
Python 3.7.0 (default, Oct  3 2018, 21:22:25) 
[GCC 5.5.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import pandas as pd
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'pandas'

So I tried to run from python ,

user@client3:~/smith/Python$ python
Python 2.7.12 (default, Nov 12 2018, 14:36:49) 
[GCC 5.4.0 20160609] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pandas as pd
>>> exit()

It works fine here. So I tried to install pandas for python3 as follows,

user@client3:~/smith/Python$ sudo apt-get install python3-pandas

It already installed for python3 . What happened here? Why it doesn't run for python3?
