How to use the xlrd/xlwt/xlutils module for Python Excel data processing-Python Tutorial-php.cn

Conventional Excel data processing involves reading/writing/file object operations on Excel data files.

The specific data processing business logic is implemented through the corresponding python non-standard library xlrd/xlwt/xlutils.

In the complex Excel business data processing, the three brothers play indispensable roles. Today our content is about how to use the three modules of xlrd/xlwt/xlutils to implement data processing.

1. Module Description

The best thing about using these three modules to process Excel data is that they have the same data processing concept as the Excel file object, which can better facilitate us. Understand data objects.

First of all, these three modules are non-standard libraries of python, and you can choose pip to install them.

pip install xlrd pip install xlwt pip install xlutils

How to use the xlrd/xlwt/xlutils module for Python Excel data processing

xlrd: used to read the Excel data file, put the returned data object into the memory, and then query the relevant information of the data file object.

xlwt: Used to generate a new data file object in the memory, and write it to the Excel data file after the processing is completed.

xlutils: The main function is to copy new file objects and complete data processing operations in new data objects.

Import the three modules xlrd/xlwt/xlutils into the code block to be developed to provide support.

# Importing the xlrd module. import xlrd as read # Importing the xlwt module. import xlwt as write # Copying the contents of the original workbook into a new workbook. from xlutils.copy import copy
