Python AttributeError: module 'runAnalytics' has no attribute 'run'

Question

我正在尝试使用 tkinter 从我的 main.py 文件中获取输入，然后在 runAnalytics.py

中使用该输入

main.py

import runAnalytics
import tkinter
import os
import centerWindow

loadApplication = tkinter.Tk()
loadApplication.title("Stock Analytics")
loadApplication.geometry("1080x720")

label1 = tkinter.Label(loadApplication, text = "Ticker")
input1 = tkinter.Entry(loadApplication)

loadAnalytics = tkinter.Button(loadApplication, text = "Load Analytics", command = runAnalytics.run)

centerWindow.center(loadApplication)

loadAnalytics.pack()
label1.pack()
input1.pack()

loadApplication.mainloop()

runAnalytics.py

from yahoo_finance import Share
from main import input1
import tkinter
import os
import centerWindow


def run():
    ticker = input1
    loadAnalytics = tkinter.Tk()
    loadAnalytics.title("$" + ticker + " Data")
    loadAnalytics.geometry("1080x720")

    print ("Price per share: " + ticker.get_price())

    ticker.refresh()
    print ("Price per share: " + ticker.get_price())

    print("The dividend yield is: " + ticker.get_dividend_yield())

    print("The 52 week low is: " + ticker.get_year_low())
    print("The 52 week high is: " + ticker.get_year_high())
    print("The volume is: " + ticker.get_volume())

    print("The previous close was: " + ticker.get_prev_close())
    print("The previous open was: " + ticker.get_open())

    loadAnalytics.mainloop()

我的错误信息如下；

Traceback (most recent call last):
  File "C:\Users\MyName\Documents\Python Projects\MarketData\main.py", line 1, in <module>
    import runAnalytics
  File "C:\Users\MyName\Documents\Python Projects\MarketData\runAnalytics.py", line 2, in <module>
    from main import input1
  File "C:\Users\MyName\Documents\Python Projects\MarketData\main.py", line 13, in <module>
    loadAnalytics = tkinter.Button(loadApplication, text = "Load Analytics", command = runAnalytics.run)
AttributeError: module 'runAnalytics' has no attribute 'run'

Answer 1

尝试将 () 添加到 runAnalytics.run 的末尾。您目前正在告诉它寻找它没有的 run 属性而不是函数

loadAnalytics = tkinter.Button(loadApplication, text = "Load Analytics", command = runAnalytics.run())

Answer 2

from runAnalytics import run

loadAnalytics = tkinter.Button(loadApplication, text="Load Analytics", command=run)

您不想开始 tk 的另一个 mainloop。相反，您应该传递 root 并创建顶层 window.

def run(root):
    ticker = input1
    parent = Toplevel(root)
    parent.title("$" + ticker + " Data")
    # the rest of your code

Answer 3

你有一个循环导入：

import runAnalytics
# ..
from main import input1

再次导入 main 时，runAnalytics 还没有机会执行 def run():.. 部分。

通过删除 from main import input1 行解决此问题，并将该对象作为参数传递：

def run(input1):

调用函数时从 main.py 模块传入：

loadAnalytics = tkinter.Button(loadApplication, text = "Load Analytics", command = lambda: runAnalytics.run(input1))

除了循环导入之外，还有一个问题是，无论你运行作为主脚本在Python中的什么文件都会被存储为__main__模块。再次导入同一脚本将导致创建 second 模块，现在名称为 main，并且在该模块中创建的任何对象都不同于 __main__ 中的对象].

接下来，您需要删除来自 run 的 loadAnalytics.mainloop() 调用，因为您不应该从已经运行宁循环。您可能还想创建一个新的 TopLevel window 而不是创建另一个 Tk() 根。如果你这样做，你也必须将 loadApplication 传递给 run。
