在函数之间传递文件数据

Question

在下面的简化代码中，我将从功能OpenFile中的文件中获取（大量）数据，并且我想在另一个功能ss中使用该数据，而不必再次从该文件中读取数据。这可能吗，如果可以，我该怎么做？我认为这等效于在函数之间传递变量，但是我似乎无法解决这个问题或在这种情况下如何应用它。预先感谢您的协助以及您对我的新手技能的耐心配合。

from Tkinter import *

from tkFileDialog   import askopenfilename, asksaveasfile

def OpenFile():

    gen = []

    fam = []

    OTUs = []

    save_fam = []

    save_gen = []

    save_OTU = []

    FindIT_name = askopenfilename()

    data = open(FindIT_name, "r").readlines()

    #some data manipulation here

def ss():

    ss_file = asksaveasfile(mode="w", defaultextension=".csv")

    ss_file.write("OTU, Family, Genus")

    #I want to get data here, specifically data from FindIT_name (see OpenFile function) 

root = Tk()

root.minsize(500,500)

root.geometry("500x500")

root.wm_title("Curate Digitized Names")

menubar = Menu(root)

filemenu = Menu(menubar, tearoff=0)

filemenu.add_command(label="Get FindIt Input", command=OpenFile)

filemenu.add_separator()

filemenu.add_command(label="Quit", command=stop)

menubar.add_cascade(label="File", menu=filemenu)

root.config(menu=menubar)

root.mainloop()

老实说，这对于我来说真的是太多代码了，但通常来说，您想要在函数之间传递数据的方式是这样的：def foo(file_path):&nbsp; &nbsp; data = open(file_path, 'rb').read()&nbsp; &nbsp; result = bar(data)def bar(data):&nbsp; &nbsp; ### do something to data对于您的原始示例，可以使用以下方法：def OpenFile（）：gen = []fam = []OTUs = []save_fam = []save_gen = []save_OTU = []FindIT_name = askopenfilename()ss(FindIT_name)data = open(FindIT_name, "r").readlines()#some data manipulation heredef ss(FindIT_name):&nbsp; &nbsp; ss_file = asksaveasfile(mode="w", defaultextension=".csv")&nbsp; &nbsp; ss_file.write("OTU, Family, Genus")&nbsp; &nbsp; ### If you need to do something, you now have FindIT_name available.
