Check if images is a list of images or a single image

To check if `images` is a list of images or a single image, you can use the `isinstance()` function in Python. Here's an example code snippet:
```
if isinstance(images, list):
# images is a list of images
else:
# images is a single image
```
This code checks if `images` is an instance of the `list` class in Python. If it is, then `images` is a list of images. Otherwise, it is assumed to be a single image.

Write a function which check if provided variable is a valid python variable
名。(编写一个函数来检查提供的变量名是否是有效的 Python 变量名。))
可以按照以下方式创建一个这样的函数:
```python
import keyword
def is_valid_variable_name(variable_name):
"""
Check if provided variable name is a valid Python variable name.
"""
if not variable_name.isidentifier() or keyword.iskeyword(variable_name):
return False
return True
```
该函数使用 Python 内置的 `isidentifier()` 函数来检查变量名是否是有效的标识符。它还使用 `keyword.iskeyword()` 函数来检查变量名是否是 Python 关键字。如果变量名是有效的 Python 变量名,则该函数将返回 `True`,否则返回 `False`。
if you shell is Bash or a Bourne variant
As an AI language model, I don't have a shell. However, if you are using a Bash or Bourne shell, you can check by typing the following command in the terminal:
```
echo $0
```
If the output is `/bin/bash`, then you are using the Bash shell. If the output is `/bin/sh`, then you are using a Bourne shell variant.
