如何将字符串中的 %20 转换为 space？

Question

我从 tkinter 对话框中获取一个字符串 window:

from tkinter import filedialog
def get_register_path_and_filename(initialfile=""):
    filename = filedialog.asksaveasfilename(initialfile=initialfile, title="Register file",
                                            filetypes=[("Excel Files", ".xlsx")])

    if filename == "":
        print("pas d'enregistrement")
        return None
    print(filename)
    return filename

if __name__ == "__main__":
    from tkinter import Tk

    app = Tk()
    get_register_path_and_filename("totolabrebis")
    app.destroy()

打印显示正常 space 但是当我尝试注册 pdf 时，它将所有 space 转换为 %20：例如：“toto la brebis.pdf”->“toto%20la%20brebis.pdf”

import win32com.client

def register_pdf(excel_path, tab_to_display_list):
    if not excel_path[-5:] == ".xlsx":
        print("error excel_to_pdf.py l37:",excel_path,excel_path[-5:])
        return None
    pdf_path = excel_path[:-5]+".pdf"
    print(pdf_path)


    try:
        excel_obj = win32com.client.Dispatch("Excel.Application")
        excel_obj.Visible = False    
    except Exception as e:
        print(e)
        print("error excel_to_pdf.py l46")
        return None
    try:
        wb = excel_obj.Workbooks.Open(excel_path)
    except Exception as e:
        print(e)
        print("error excel_to_pdf.py l52")
        return None
    tab_id_to_display_list = []
    for i in range(1,len(wb.Sheets)+1):
        tab_name = wb.Sheets(i).Name
        if tab_name in tab_to_display_list:
            tab_id_to_display_list.append(i)
    try:
        print([(i,wb.Sheets(i).Name) for i in tab_id_to_display_list])
        wb.WorkSheets(tab_id_to_display_list).Select()
        wb.ActiveSheet.ExportAsFixedFormat(0, pdf_path, IgnorePrintAreas=True)
        
        wb.Close(True)
        excel_obj.Quit()
    except Exception as e:
        print(e)
        print("error excel_to_pdf.py l60")
        return None
    print("successfully registered pdf")
    return pdf_path

if __name__ == "__main__":
    excel_path = "D:\Bureau\toto 3.xlsx"
    tab_to_display_list = ["Feuil1"]
    pdf_state = register_pdf(excel_path,tab_to_display_list)

所以我的假设是 tkinter.filedialog.asksaveasfilename return 一些使用 %20 而不是 space 的奇怪编码。

我试过“r”“b”编码（“utf-8”）解码（“utf-8”）html.unescape（pdf_path）urllib.parse.unquote（pdf_path) replace ("%20", " ") 我真的哭得很厉害，因为今天是星期天，我因为这个错误度过了下午 :s

这是一个肮脏的解决方案，但它有效... 如果名字很奇怪，你重命名文件...

from os.path import isfile
from os import rename
if not isfile(pdf_path):
    print("the weird problem of space becoming %20")
    weird_pdf_path = pdf_path.replace(" ","%20")
    if isfile(weird_pdf_path):
        rename(weird_pdf_path, pdf_path)
