在python中导入多个文件

Question

我正在尝试创建一个脚本，用户可以在其中选择文件夹中的1个或所有文件（以“模仿” Matlab中uigetfile的多选打开）。 之后，脚本将询问用户是否要从另一个位置导入数据，并且导入1或所有例程将继续。

该脚本的任务只是检索多选选项的路径和文件名。 它是使用Windows 10在PC上编写的，Python 3.6和Spyder作为Anaconda Distro中的IDE。

到目前为止，我有这个：

def import_multiple_files(): 
    # Similar to UIGETFILE
    import tkinter as tk
    from tkinter import filedialog
    from tkinter import messagebox
    import glob


    root = tk.Tk()
    root.withdraw()
    root.attributes("-topmost", True)
    root.lift()
    file_location = filedialog.askopenfilename()
    a=file_location.split('/')
    path=[]
    for i in range(0,len(a)-1):
        path.append(a[i])

    path= "/".join(path)    
    filename=a[len(a)-1]

    # Questions the user

    qst=messagebox.askyesno("Multiple Import","Do you want to import all .txt files in this folder?")
    allFiles=[]

    if qst==True:

    # Gets all .txt files in path FOLDER

        b=glob.glob(path + "/*.txt") # glob. lists the filename and path

        allFiles.append(b)
    else: 
        b=(path + "/"+ filename)
        allFiles.append(b)

    qst=messagebox.askyesno("Multiple Import","Do you want to import more DATA?")   


    finish=0    
    while finish==0:
        if qst==True:

        # deletes all variables except "AllFILES" (location of all files to import)
            del(root,file_location,a,path,qst,b)

            root = tk.Tk()
            root.withdraw()
            root.attributes("-topmost", True)
            root.lift()
            file_location = filedialog.askopenfilename()
            a=file_location.split('/')
            path=[]
            for i in range(0,len(a)-1):
                path.append(a[i])

            path= "/".join(path)    
            filename=a[len(a)-1]

            qst=messagebox.askyesno("Multiple Import","Do you want to import all .txt files in this folder?")

            if qst==True:
                # Gets all .txt files in path FOLDER
                b=glob.glob(path + "/*.txt")
                allFiles.append(b)
                qst=messagebox.askyesno("Multiple Import","Do you want to import more DATA?") 
            else: 
                b=(path + "/"+ filename)
                allFiles.append(b)
                qst=messagebox.askyesno("Multiple Import","Do you want to import more DATA?") 

        else:
            finish=1

    return(allFiles)


file_location=import_multiple_files()

脚本/函数返回完整路径和文件名，但是，出于某些原因，某些名称带有双反斜杠

例如，

file_location
[['C:/Users/user/Desktop/New Folder (2)\\1.txt',
  'C:/Users/user/Desktop/New Folder (2)\\2.txt',
  'C:/Users/user/Desktop/New Folder (2)\\3.txt'],
 ['C:/Users/user/Desktop/New Folder (3)/1.txt']] # For this last file, I did not select the option of importing all files.

任何人都可以友好地看一下这个脚本，看看是否有问题，或者这仅仅是Python显示事物的方式。

先感谢您！

Answer 1

\\\\就是Python显示转义的反斜杠的方式。 \\在许多上下文中用于表示换行符（ \\n ），制表符（ \\t ）等。因此\\\\仅表示反斜杠之后出现的内容不是这些特殊字符之一。 Python将使您理解正斜杠和反斜杠的混合使用，但是如果要使所有内容一致显示，则可以使用[os.path.abspath(d) for d in my_list] 。

同样，如果您要避免创建列表列表，则似乎应该使用extend而不是append 。

这是“最终”版本

谢谢你们！

此功能检索一个文件夹中1个或所有文件的文件位置。
