# 导入pandas库并取别名pd
import pandas as pd

# 读取Nowcoder.csv文件,得到DataFrame对象nowcoder
nowcoder = pd.read_csv("Nowcoder.csv")
# 选取Continuous_check_in_days列,存储在days中
days = nowcoder["Continuous_check_in_days"]
# 使用days.max()得到最长的连续签到天数,存储在max_days中
max_days = days.max()
# 使用days.min()得到最短的连续签到天数,存储在min_days中
min_days = days.min()
# 打印max_days和min_days
print(max_days, "\n", min_days)
