爲什麼Python在我的字符串中的數字之前顯示一個撇號？

我正在編寫一個程序，根據Google電子表格中的數據爲家人創建一個目錄條目。其中一項職能是列出家庭中的任何兒童以及他們的生日。然而，該程序在生日之前沒有明顯的原因打印撇號，例如， '01/01/01，我不明白爲什麼。我已將生日的數據轉換爲字符串，而其他字符串不會執行此操作。這是爲什麼發生？爲什麼Python在我的字符串中的數字之前顯示一個撇號？

這裏是源代碼的相關部分：

import gspread 
    gc =gspread.login('mylogin','password') 
    spreadsheet = gc.open_by_key("mykey") 
    worksheet = spreadsheet.get_worksheet(0) 
    Child1=(worksheet.cell(x,13)).value 
    Child1BD=(worksheet.cell(x,14)).value 
    Child2=(worksheet.cell(x,15)).value 
    Child2BD=(worksheet.cell(x,16)).value 
    Child3=(worksheet.cell(x,17)).value 
    Child3BD=(worksheet.cell(x,18)).value 
    Child4=(worksheet.cell(x,19)).value 
    Child4BD=(worksheet.cell(x,20)).value 
    # If there are no children, return without doing anything. 
    if Child1 == "n/a": 
     return; 
    # If there is one child only, print the child's name and birthday. 
    elif Child2 == "n/a" and Child1 != "n/a": 
     print str(Child1)+"- "+str(Child1BD) 
     return; 
    # If thre are exactly two children, print their names and birthdays. 
    elif Child3 == "n/a" and Child2 != "n/a": 
     print str(Child1)+"- "+str(Child1BD) 
     print str(Child2) +"- "+str(Child2BD) 
     return; 
    # If there are exactly three children, print their names and birthdays. 
    elif Child4 == "n/a" and Child3 != "n/a": 
     print str(Child1)+"- "+str(Child1BD) 
     print str(Child2) +"- "+str(Child2BD) 
     print str(Child3) +"- "+str(Child3BD) 
     return; 
    # If there are four children, print their names and birthdays. 
    elif Child4 != "n/a": 
     print str(Child1)+"- "+str(Child1BD) 
     print str(Child2) +"- "+str(Child2BD) 
     print str(Child3) +"- "+str(Child3BD) 
     print str(Child4) +"- "+str(Child4BD) 
     return;

'print repr（Child1）'打印出來了什麼？ – Blender 2013-03-07 03:33:32
