How to input a tuple in RGB to hex converter?
问题
我原本打算编写一个简单的RGB转十六进制颜色代码，但后来在处理元组输入时出现了问题。程序如下：
rgb_val = input('输入RGB值: ')
for val in rgb_val.split(','):
rgb = tuple(val)
hex_color = '#' + ''.join([f'{channel:02x}' for channel in rgb])
print(f'将{rgb}转换为{hex_color}')
错误出现在第4行，VSCode显示：对象类型为'str'，未知的格式代码'x'。
:02x用于将RGB值转换为具有2位数的十六进制，并在位数少于2位数时用零填充数字。所以：
- 我不明白x的问题在哪里。
- 有人能提出一种处理元组输入的方法，以避免上述错误吗？
有人知道如何解决这个问题吗？提前感谢。

I intended to code a simple RGB to hex color converter but then I had a problem with tuple input. The program looks like this:
rgb_val = input('Input RGB values: ')
for val in rgb_val.split(','):
rgb = tuple(val)
hex_color = '#' + ''.join([f'{channel:02x}' for channel in rgb])
print(f'Convert {rgb} to {hex_color}
The error is in line 4 and VSCode stated: Unknown format code 'x' for object of type 'str'
:02x is used to convert the RGB values into hexadecimal with 2 figures and pad the number with zeroes if we have fewer than 2 figures. So
- I don't understand what the problem was with x.
- Can anyone suggest a way to work with tuple input so I don't run into the above error?
Does anyone know how to fix this? Thanks in advance.

因为 "channel" 是字符串类型，所以需要转换为整数类型。
英文:
Because "channel" is a string type.You need to transfer to integer type.
