【问题描述】：

我有一个 python 文件 bucket.py。我正在尝试使用下面的代码将其导入到 jupyter 笔记本中。然后，我尝试使用其中的一个函数“exp1”来探索数据框。我收到以下错误。有人可以告诉我如何从目录中导入文件，以便我可以在我的 jupyter 笔记本中使用其中的功能吗？

代码：

import importlib.util
spec = importlib.util.spec_from_file_location("module.name", '/Users/stuff/bucket/bucket.py')
foo = importlib.util.module_from_spec(spec)


foo.exp1(df)

错误：

---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
<ipython-input-9-e1cc80f06e24> in <module>
----> 1 foo.exp1(harborsideoakland_df)

AttributeError: module 'module.name' has no attribute 'exp1'

bucket.py 文件：

### HELPER FUNCTIONS:

def exp1(df):

    with pd.option_context('display.max_rows', None, 'display.max_columns', None):
        # shape of data

        print('rows and columns: '.format(df.shape))

        # head data

        # display(df.head())
        print('')
        # data types and columns in data
        print('data types and columns in data:')
        print('')
        #display(df.info())
        print(df.info())
        print('')
        # unique values in each column
        print('unique values in each column:')
        #display(df.nunique())
        print(df.nunique())
        print('')
        # percentage duplicates
        print('percentage duplicates : '.format(1-(float(df.drop_duplicates().shape[0]))/df.shape[0]))
        print('')
        ## Percentage of column with missing values
        print('Percentage of column with missing values:')
        print('')
        missingdf=df.apply(lambda x: float(sum(x.isnull()))/len(x))

        #display(missingdf.head(n=missingdf.shape[0]))
        print(missingdf.head(n=missingdf.shape[0]))
        print('')
        print('Data snapshot:')
        print('')

        print(df[:5])

【参考方案1】：

这行得通：

import sys
sys.path.append(r'/Users/stuff/bucket/bucket')
import bucket as Lb
