python learning-110- merging of multiple xlsx files (including graphical interface)

Foreword:

A few days ago, there was a program for merging multiple CSV files (including a graphical interface), but after thinking about it, most of the CSV files are used by programmers or people studying IT. Most people may still use xlsx or xls files. It is used a lot, so today I will share with you a Python program that combines xlsx files. For the convenience of use, I also wrote a graphical interface. The program is compatible with xlsx and xls for common use.

note:

To use pip to install pandas to read the dependency package xlrd of xlsx files

pip install xlrd

At the same time, it also gives the command to package into a desktop program.exe

1. Source code

#coding:utf-8
import pandas as pd
import os
import datetime

def xlsx_fileMerage(inputfilePath, outputfile):
    '''
    讲xlsx文件进行合并成CSV文件，兼容xls文件
    :param inputfilePath:
    :param outputfile:
    :return:
    '''
    # 定义列名
    columns = ['姓名', '学校', '学号', '成绩', '四级', '六级', '性别', '985', '211']
    dataframe = pd.DataFrame([columns])
    dataframe.to_csv(outputfile, encoding='utf-8', index=False, header=0)
    # 合并文件
    rightCount = 0
    errorCount = 0
    for file in os.listdir(inputfilePath):
        try:
            data=pd.read_excel(inputfilePath+'/'+file)
            dataframe=pd.DataFrame(data)
            dataframe.to_csv(outputfile,mode='a', index=False, encoding='utf-8', header=0)
            rightCount += 1
        except:
            print(file + '文件有误')
            errorCount += 1
    print('文件合并完成 ',rightCount,'个文件成功',errorCount,'个文件有误')



if __name__ == '__main__':
    inputfilePath = 'data2'
    outputfile='data/合并文件2.csv'
    xlsx_fileMerage(inputfilePath, outputfile)

2. With graphical interface code

    if dialog.ShowModal() == wx.ID_OK:
        filename.SetValue(dialog.GetPath())
    dialog.Destroy()

def gettime():
    '''
    :return: 当前时间的规范形式
    '''
    now_time = datetime.datetime.now().strftime('%Y-%m-%d %H-%M-%S')
    return now_time

    informationLog += ' 文件合并完成: ' + str(rightCount) + ' 个文件成功, ' + str(errorCount) + ' 个文件有误 '
    contents.SetValue(informationLog)

    contents.SetValue(informationLog)
