使用 Python 和 SQL 时出现 NamError

Getting a NamError when using Python and SQL

我是 运行 学生数据库,在 pycharm 上使用 python 2.7。这是脚本

FirstName = input("Enter the Student's first name")
    if not FirstName or type(FirstName) != str:
    print("Enter a real name silly")
    exit()

创建 Table 语句看起来像这样

drop table if exists StudentID;
drop table if exists FirstName;
drop table if exists LastName;
drop table if exists GPA;
drop table if exists Major;
drop table if exists FacultyAdvisor;
CREATE TABLE Student(
  StudentID int PRIMARY KEY AUTOINCREMENT ,
  FirstName varchar(25),
  LastName varchar(25),
  GPA NUMERIC,
  Major varchar(10),
  FacultyAdvisor varchar(25)
)

我得到的错误是

FirstName = input("Enter the Student's first name")
  File "<string>", line 1, in <module>
NameError: name 'john' is not defined

我猜你正在使用 Python2

接收用户输入的字符串需要使用raw_input()方法:

FirstName = raw_input("Enter the Student's first name")
