Extract certain value in column treeview

I have tried alot of things but cannot get it to work. Basically what im trying to do in this block is create a button that will create a pdf of my treeview. All i want to do is for each row in my treeview that has data is to extract data only from one of the columns "line" and put into a pdf. is it because the line pdf.cell(200, 10, txt=word, ln=1, align='L') has txt which does not work with the string variable word? Help is appreciated!

def create_pdf():
    # save FPDF() class into a variable pdf
    pdf = FPDF()
    # Add a page
    pdf.add_page()
    word = StringVar()

    for line in tree.get_children():
        pdf.set_font("Arial", size=10)
        # for value in tree.item(line)['values']:
            # word = [set(value)]
        word.set((line, 'Line'))
        pdf.cell(200, 10, txt=word, ln=1, align='L')
    pdf.output("GFG.pdf")
    return None


createpdf = Button(frame5, text="Create PDF", relief=GROOVE, command=create_pdf, width=10)
createpdf.place(x=1668, y=10, height=30)

word is a StringVar, so txt=word is not working.

Actually you don't need to use StringVar at all. Also you need to use tree.set(line, 'Line') to get the value of the column Line of row line:

def create_pdf():
    # save FPDF() class into a variable pdf
    pdf = FPDF()
    # Add a page
    pdf.add_page()

    pdf.set_font("Arial", size=10)
    for line in tree.get_children():
        # get the value of the cell in column 'Line'
        word = tree.set(line, 'Line')
        pdf.cell(200, 10, txt=word, ln=1, align='L')
    pdf.output("GFG.pdf")
