# 导入pandas库
import pandas as pd

# 读取Nowcoder.csv文件,得到DataFrame
nowcoder = pd.read_csv("Nowcoder.csv")

# 选择Level列为7的行
level = nowcoder[nowcoder["Level"] == 7]

# 获取Achievement_value列的最大值
achievement_max = level["Achievement_value"].max()

# 获取Achievement_value列的最小值
achievement_min = level["Achievement_value"].min()

# 计算最大值与最小值的差值
diff = achievement_max - achievement_min

# 输出差值
print(diff)
