我想将飞机外壳和呼号外壳合并为一个外壳

from pandas import DataFrame
import pandas as pd

def ShowResult(column):

    if(column=='callsign'):
        data = pd.read_excel (r'D:\Pandas\1 (179).xlsx',skiprows=3)
        df = pd.DataFrame(data, columns= ['callsign'])
        print (df)


field = input("Enter Field Name : ")
ShowResult(field)
