如何将 csv 文件加载到 pandas 以在数据框中使用它

Question

I am a beginner who is having trouble loading csv files into pandas dataframe.

The code which I am trying to run in a jupyter notebook is:

df_census = pd.read_csv('census.csv')

Then I have created a function which accepts the dataframe as a function parameter:

def explore_df(df):
    df.show()

But I am getting error while calling the function

explore_df(df_census)

The error message is:

NameError                                 
Traceback (most recent call last)
<ipython-input-11-e557e519fd3d> in <module>
----> 1 explore_df(df_census)
NameError: name 'df_census' is not defined

Not sure what show() does. If you would like to see what was loaded. Just print it.

import pandas as pd

df_census = pd.read_csv('census.csv')

def explore_df(df):
    #df.show()
    print(df)

explore_df(df_census)
