python函数练习题

写一段代码，用于识别姓名（first_name,last_name)

结合使用函数get_formatted_name()和while循环，以更正规的方式问候用户

面尝试使用名和姓跟用户打招呼

def get_formarted_name(first_name,last_name,middle_name=‘‘):
    if middle_name:
        full_name=first_name+‘ ‘+middle_name+‘ ‘+last_name
    else:
        full_name=first_name+‘ ‘+last_name
    return full_name.title()

while True:
    print("\nPlease tell me your name: ")
    f_name = input("First name: ")
    l_name = input("Last name: ")
    m_name = input("Middle name: ")

    formatted_name=get_formarted_name(f_name,m_name,l_name)
    print("\nhello, "+formatted_name+"!")
    choice=input("\nDo you want tell me another name? (y or n)")
    if choice == ‘y‘:
        continue
    else:
        break
