pycharm pandas运行输出错误

问题遇到的现象和发生背景

在pycharm中运行pandas输出时报错

用代码块功能插入代码，请勿粘贴截图

import pandas as pd
df = pd.read_csv('pima-indians-diabetes.csv',index_col=0)

print(pd.Series(df))

报错内容：
Traceback (most recent call last):

print(pd.Series(df))
File "/Users/mac/PycharmProjects/sx/venv/lib/python3.8/site-packages/pandas/core/series.py", line 386, in init

我的解答思路和尝试过的方法
我想要达到的结果解决报错，成功输出

pd.Series(df)这是什么用法，df是DataFrame，series是一个一维数组，pd.Series可以操作列表和字典。
如果要输出csv文件，那直接print(df)不就完了，如果输出某一列，print(df['列名'])
