如何在文件对话框中放置默认文件名asksaveasfile python

Question

当用户保存文件时，我想默认在文件对话框中放置一个值。任何人都可以建议它的语法吗？

saveFilePath = fileDialog.asksaveasfile(mode='w', title="Save the file", defaultextension=".txt")

例如：打开文件对话框时应填写NewFile

Answer 1

排序答案是在您的 saveFilePath 中使用：intialfile = 'default_file_name'。下面是一个 Python 3 块，您可以使用它从 CSV 读取数据帧并使用 tkinter“另存为”。

    def ExportApplications():
        #reads the file to dataframe
        df_testFile = pd.read_csv('test.csv')

        #creates SaveAs dialogue and prompts user to save
        #you can enter multiple file type formats in data FYI
        data = [('csv', '*.csv')]
        file_out = asksaveasfile(filetypes=data, defaultextension=data,initialfile = "This_is_the_default_file_name_when_saving")

        #writes output to location specified by user in "Save As" dialogue
        df_testFile.to_csv(file_out, index=False, encoding="utf-8")

Answer 2

请尝试以下操作：

saveFilePath  =  filedialog.asksaveasfilename(initialdir = "/<file_name>",title = "Select file",filetypes = (("jpeg files","*.jpg"),("all files","*.*")))
