'How to import python package like nltk in jython?

I am trying to import nltk in Jython and calling that from java file but it is showing "no module found" error.

Test.java:

PythonInterpreter interp = new PythonInterpreter();
System.out.println("Hello, world from Java");
interp.execfile("main.py");

main.py:

import sys;
import os;
import nltk;
from nltk import word_tokenize

Solution 1:[1]

When reset_index() is used, it adds the old index as a column in the dataframe. You can set drop = True to drop the old indexes:

reset_index(drop = True)

Solution 2:[2]

This sounds like a simpler solution to me.

df1['Ti'] = 'am'
df2['Ti'] = 'pm'

new_def = df1.append(df2)
