How to import an Excel file to Python? [New to Python]

Question

I'm currently using the following code (as learned in the DataCamp courses I followed):

import pandas as pd

pd.read_excel('C:\Users\jeenb\OneDrive\Bureaublad\Master Finance\Master Thesis\Input Python\Training Set.xlsx')

I'm getting the following error message:

SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \UXXXXXXXX escape

I've tried the following as was suggested in this forum before:

pd.read_excel('C:\\Users\\jeenb\\OneDrive\\Bureaublad\\Master Finance\\Master Thesis\\Input Python\\Training Set.xlsx')

pd.read_excel(r'C:\Users\jeenb\OneDrive\Bureaublad\Master Finance\Master Thesis\Input Python\Training Set.xlsx')

pd.read_excel(r"C:\Users\jeenb\OneDrive\Bureaublad\Master Finance\Master Thesis\Input Python\Training Set.xlsx")

All of these give the following error message:

Traceback (most recent call last):
  File "C:\Users\jeenb\AppData\Roaming\Python\Python310\site-packages\pandas\compat\_optional.py", line 126, in import_optional_dependency
    module = importlib.import_module(name)

During handling of the above exception, another exception occurred:

ImportError: Missing optional dependency 'openpyxl'.  Use pip or conda to install openpyxl.

I'm typing this code in the IDLE Shell 3.10.2. Previously I got an error message while importing the pandas however since I don't get this anymore I feel like I fixed this.

Answer 1

似乎您需要打开命令提示符，激活您正在使用的环境并输入： pip install openpyxl

Answer 2

I found the answer. Thought I would post it if anyone in the future would be struggeling with this and found this post. My slashes were facing the wrong way, just changing \ to / fixed the problem.

Answer 3

In my case of using pycharm, I needed to go to File -> settings -> Project: projectName -> Python interpreter. Then click on + button will show you a pop up window to install packages. Then you can search for openpyxl and get the latest package. Then click Install package to install it.
