    获取英文字母

    - param end   :{str|int} 结束的英文字母

    @returns `{str}` {description}
    @example
    ```py
    # 获取A之后10个英文字母
    res = get_az("A", 10)
    >>> ABCDEFGHIJ

    # 获取a到f的字母
    res = get_az("a", 'f')
    >>> abcde
    ```

获取计算名称

# 获取计算机名，常用的方法有三种，但最常用的是第一种
import os
import socket
 
# method one

print(name)  # hanser
 
# method three
name = os.environ.get("COMPUTERNAME")
print(name)  # HANSER
