nlp - Find the word behind the index numbers in python

Question

I have a question as I am new at the NLP. I have a dataframe consists of 2 columns. The first has a sentence lets say "Hello World, how are you?" and the second column has [6,7,8,9,10] which represents the word "World" (index positions) from the first sentence. Is there any function in python which can give me the opportunity to recognize and appear the word that in each row is specified by the index numbers?

Thank you

I think it's what you need (updated according to comments)

dataframe = ["Hello World",[6,7,8,9,10]],
                    ["Hello World",[6,7,8,9]],
                    ["Hello World",[7,8,9,10]]
resultdataframe=[]

def textbyindexlist(df):
    text = df[0]
    letterindex=df[1]
    newtext=""
    for ind in letterindex:
        newtext = newtext + text[ind]
    return newtext
for i in dataframe:
    resultdataframe.append(textbyindexlist(i))
print (resultdataframe)
