如何用Python3修复base62编码的代码？

import base62

def fix_base62_code(code):
    try:
        decoded = base62.decode(code)
        fixed_code = base62.encode(decoded)
        return fixed_code
    except Exception as e:
        print("修复base62编码的代码时出错：", str(e))
        return None

code = "your_base62_code_here"
fixed_code = fix_base62_code(code)
if fixed_code:
    print("修复后的base62编码：", fixed_code)
