Python陷入无限While循环?

Prophet • 6 年前 • 1974 次点击  

从目前为止的研究来看,我需要在循环之间包含break和continue语句,但是每次我试图包含那些语句时,都会得到语法错误。

如果您能帮忙完成这项工作,我们将不胜感激

    Query = 'Y'

while Query == 'Y':
   Subject = input("Enter the Subject: \n> ")
   CatalogNbr= input("Enter the CatalogNbr: \n> ")
if Subject == 'LIBS' and CatalogNbr == '150':
        print(f"The title of {Subject,CatalogNbr} is Introduction to Research")

if Query == 'N':
    print("Thank you for using the Catalog Search!")
