如何使用Python直接从服务器读取Excel文件 [英] How to read an excel file directly from a Server with Python

问题描述

场景::我试图从服务器文件夹中读取一个excel文件，然后将该文件的每个工作表读取到一个数据框中并执行一些操作.

Scenario: I am trying to read a excel file from a server folder and after that read each worksheet of that file into a dataframe and perform some operations.

问题:我尝试了多种方法，但是遇到了不同的情况:要么我读取了文件，但将其视为str，并且无法执行操作，或者无法读取文件.

Issue: I have trying multiple approaches but facing different situations: either I read the file, but it is seen as a str and the operations cannot be performed, or the file is not read.

到目前为止我尝试过的事情:

#first attempt
os.path(r'\\X\str\Db\C\Source\selection\Date\Test','r')  

#second attempt
directory = os.getcwd() + "\\C\\Source\\selection\\Date\\Test"

#third attempt
f = os.getcwd() + "\\C\\Source\\selection\\Date\\Test\\12.xlsx"

#fourth attempt
f = open(r'\\X\str\Db\C\Source\selection\Date\Test\12.xlsx', 'r')

db1 = pd.DataFrame()
db2 = pd.DataFrame()
db3 = pd.DataFrame()
bte = pd.DataFrame()
fnl = pd.DataFrame()

wb = load_workbook(f)

for sheet in wb.worksheets:

    if sheet.title == "db1":

        db1 = pd.read_excel(f, "db1")

Obs::我还研究了用于阅读pd的文档以及SO中的其他一些类似问题，但仍然无法解决此问题.前任: Python-如何从服务器读取路径文件/文件夹 使用Python，如何访问Windows网络上的共享文件夹? https://docs.python.org/release/2.5. 2/tut/node9.html#SECTION009200000000000000000

Obs: I also researched the documentation for reading with pd and some other similar questions in SO, but still could not solve this problem. Ex: Python - how to read path file/folder from server Using Python, how can I access a shared folder on windows network? https://docs.python.org/release/2.5.2/tut/node9.html#SECTION009200000000000000000

问题:实现此目标的正确方法是什么?

Question: What is the proper way to achieve this?

推荐答案

您需要以rb模式打开文件

You need to open the file as rb mode

b =常规文件 r =仅读取文件

b = bynary file r = only read the file

f = open('//X/str/Db/C/Source/selection/Date/Test/12.xlsx', 'rb')

您可以使用熊猫库可以为您完成大部分工作

You can use pandas library that will do most of the work for you

进口大熊猫

import pandas
f = pandas.read_excel(open('//X/str/Db/C/Source/selection/Date/Test/12.xlsx','rb'), sheetname='Sheet 1')
# or using sheet index starting 0
f = pandas.read_excel(open('//X/str/Db/C/Source/selection/Date/Test/12.xlsx','rb'), sheetname=2)
