Tkinter and pandas output into a label - pandas

Question

I need some assistance, I have written an application that queries all records in a table and prints it out but when I run the program it prints it out in the IDE, and trying to get it to print in the lower label.

engine = sa.create_engine(
f'mssql+pyodbc://{server}/{database}?username={username}?password={password}?timeout=
{timeout}&driver={driver}')
cn = engine.connect()

root.title("Compliance SQL Backend Reporting")

canv.create_image(20, 20, anchor='nw', image=img)
