编写Python代码遇语法错误，含按钮代码报错求助

Hey there! Let's walk through the syntax issues in your code and fix them up step by step:

Key Issues Identified #

• Invalid variable name: btn+ is not a valid variable name in Python. Variable names can only include letters, numbers, and underscores—special characters like + aren't allowed. Let's rename this to something like btn_plus or btn_add instead.
• Case-sensitive parameter name: Tkinter uses lowercase parameter names, so Border should be border (uppercase B will throw an error because it's not recognized as a valid parameter).
• Unnecessary trailing comma: The extra comma at the end of your Button arguments is harmless here, but it's cleaner to remove it to avoid any potential confusion down the line.

Corrected Code #

# Make sure you've imported Tkinter components first
from tkinter import Button

# Assuming btnrow1 is a pre-defined frame/widget container
btn_add = Button(
    btnrow1,
    text="+",
    font=("Verdana", 22),
    relief="GROOVE",
    border=0
)
btn_add.pack(side="LEFT", expand=True, fill="both")

This code should run without syntax errors now—just double-check you've properly set up your Tkinter window and the btnrow1 container before using this button code.
