python中函数与while循环结合

1、

def a(first,last):
    full = f"{first} {last}"
    return full.title()

while True:                 ## 条件为真的话，一直循环
    print("\n\nplease tell me your name:")        ## 两个\n,每执行一次循环，空出两行
    print("(enter 'q' to quit in any time)")
    fname = input("first name:")
    if fname == "q":                            ## 设置退出条件
        break
    lname = input("last name:")
    if lname == "q":
        break

    name = a(fname,lname)
    print(f"hello, {name}")

please tell me your name:
(enter 'q' to quit in any time)
first name:aaaaa
last name:bbbbb
hello, Aaaaa Bbbbb


please tell me your name:
(enter 'q' to quit in any time)
first name:mmmm
last name:nnnn
hello, Mmmm Nnnn


please tell me your name:
(enter 'q' to quit in any time)
first name:q
