How to combine two columns in pandas?

Question

Df= Dataframe({'num1':[1,2,3], 'num2': [4,5,6]}
And result= [1,2,3,4,5,6]

Answer 1

Nabanita Borkakoti you need two square brackets to insert a list into a cell.

import pandas as pd
df= pd.DataFrame({'num1':[[1,2,3]], 'num2': [[4,5,6]]})

df['result']= df['num1']+ df['num2']
print(df)
