“level = line[3].rstrip()”的列表索引超出范围错误。仔细检查了所有内容，我在显示之前打印了列表，并显示了超过 4 个值（我正在尝试获取其中的第四个）。下面的代码和回溯，谢谢！
代码：
async def lbcmd(ctx):
el = []
for file in os.scandir(lpath):
if file.path.endswith(".txt"):
with open(file, 'r') as f:
line = f.readlines()
level = line[3].rstrip()
xp = line[0].rstrip()
exp = {
"user": file.name.strip(".txt"),
"exp": xp,
"level": level
}
el.append(exp)
el.sort(reverse=True, key=operator.itemgetter('exp'))
desc = ("""
""")
for exp in el:
desc = desc + f"""Level {exp['level']} at {exp['exp']} exp - <@{exp['user']}>
"""
embed=discord.Embed(title=f"Level leaderboard", description=desc, color=0x2f3136)
await ctx.send(embed=embed)
追溯：

The above exception was the direct cause of the following exception:
