尝试在python中运行文件，但出现错误

Question

我正在登录以运行程序，但是当我尝试在程序末尾运行文件时，会抛出错误

while True:
        login1 = input("Login:")
        login2 = input("Password:")
        file = open(login1+".txt", "r")
        data   = file.readline()
        file.close()
        if data == login1+":"+login2:
            print("Welcome")
            exec(open(r"E:\Coding\Python AI project").read())
            break
        print("Incorrect username or password.")

我希望它运行文件，但会引发错误

Traceback (most recent call last):
  File "E:/Coding/login.py", line 27, in <module>
    exec(open(r"E:\Coding\Python AI project").read())
