如何将变量的内容写入文本文件（python）

Question

I'm trying to figure out how to write the content of a StringVar to a text file in python. Basically I have a dropdown menu and a string variable called value_inside that is the value that the user picks in the dropdown menu. Once the code prints the value that the user picks, I want it to be able to write that value into a text file, but when I try file=open("file.txt", "w") file.write(value_inside) I get an error that says "argument must be str, not StringVar". I think this means that I can't write string variable to a file. Do I need to convert it into something else? Or do I need to put a function that writes the actual value of the string variable into a file? Thank you for your help.

Answer 1

You actually need to invoke the .get() method to get the contents of tk.StringVar()

file=open("file.txt", "w") 
file.write(value_inside)
