Excel文件转Python字典

Question

I have an Excel table where Column A is a list of emails and column B is a customer ID.

I need to create a Python dictionary and have key=email address and value = customer ID .

Desired results:

dict = {email@domain.com :'customer ID'}

My code is below:

import pandas as pd
excel = "excel_file.xlsx"
list_dict = pd.read_excel(excel, index_col=0).to_dict()
print list_dict

However the dictionary is printing like this:

{u'customer ID': {u'email@domain.com': u'customer ID}}

What am I doing wrong here?

Answer 1

If your excel file looks like this:

Then you could do:

import pandas as pd
excel = "excel_file.xlsx"
list_dict = pd.read_excel(excel, header=None).to_dict('list')
print {k: v for k, v in zip(*list_dict.values())}

(tested on Python3, im sure it works in Python2 as well -> be careful about Unicode)

Output:

C:\projects\python\test\so_pandas_dict>python main.py
{'example@gmail.com': 'customer ID', 'example1@gmail.com': 'customer ID1'}
