Question

当在其中一个菜单中按下按钮时，我需要加载一个单独的python文件中的测验。我尝试使用import，但是它会导致其他python文件立即运行，而不是仅在按下按钮时运行，

Lines <- "some useless log information... 1
some useless log information... 2
some useless log information... 3
some useless log information... 4
some useless log information... 5
some useless log information... 6
some useless log information... 7
some useless log information... 8
some useless log information... 9

https//:url1.com,LS4465,15"

writeLines(Lines, "Minardi.csv")

Answer 1

如果使用python内置函数exec会怎样？

您可以使用此功能加载文件：

def exec_file(file_name):
    #open the file
    with open('your/file.txt') as fh:
        #read it
        data = fh.read()
    #execute it
    exec(data)

Answer 2

您可以使用importlib加载python文件。

from os import path
from importlib.util import module_from_spec, spec_from_file_location

spec = spec_from_file_location("module.name", path.join(PATH, 'file.py'))
module = module_from_spec(spec)
spec.loader.exec_module(module)

Answer 3

尝试：

import FSMQuiz1

def selectTask():
            screen7 = Toplevel(screen5)
            screen7.geometry("600x450+686+254")
            screen7.title("Select a task")
            Label(screen7, text = "Please select a task...", font = ("Calbiri",14)).place(relx=0.25, rely=0.044, height=41, width=304)
            Button(screen7, text = "Finite State Machines", command = lambda: FSMQuiz1).place(relx=0.15, rely=0.2, height=54, width=117)

Answer 4

在定义中设置按钮命令，然后使用该命令调用它，例如：

def CallButton():
    import FSMQuiz1
def selectTask():
            screen7 = Toplevel(screen5)
            screen7.geometry("600x450+686+254")
            screen7.title("Select a task")
            Label(screen7, text = "Please select a task...", font = ("Calbiri",14)).place(relx=0.25, rely=0.044, height=41, width=304)
            Button(screen7, text = "Finite State Machines", command = CallButton).place(relx=0.15, rely=0.2, height=54, width=117)

在Tkinter中按下按钮时导入新的python文件
