python 解析Excel

方法一：通過索引控制第幾行，第幾列帶讀取Excel

#coding=utf-8
__author__ = "***"
__date__ = "2018/5/30　16:50"

# 讀寫excel工作表
import  xdrlib ,sys
import xlrd
filename='E:/PycharmProjects/PycharmProjects/test_1/Directory/***.xlsx'
def open_excel(file=filename):
    try:
        data = xlrd.open_workbook(file)
        return data
    except Exception as e:
        print("文件打開失敗,str(e)是",str(e))

#根據索引獲取Excel表格中的數據   參數:file：Excel文件路徑     colnameindex：表頭列名所在行的所以  ，by_index：表的索引
def excel_table_byindex(file=filename,colnameindex=0,by_index=0):
    data = open_excel(file)
    table = data.sheets()[by_index]
    nrows = table.nrows #行數
    ncols = table.ncols #列數
    colnames =  table.row_values(colnameindex) #某一行數據
    list =[]
    for rownum in range(1,nrows):
         row = table.row_values(rownum)
         if row:
             app = {}
             for i in range(len(colnames)):
                app[colnames[i]] = row[i]
             list.append(app)
    return list

 

方法二：讀取sheet表名，畢竟一個Excel文件里可能會含有多個sheet。具體使用還看情況而定

#coding=utf-8
__author__ = "***"
__date__ = "2018/5/30　16:50"

# 讀寫excel工作表
import  xdrlib ,sys
import xlrd
filename='E:/PycharmProjects/PycharmProjects/test_1/Directory/***.xlsx'
def open_excel(file=filename):
    try:
        data = xlrd.open_workbook(file)
        return data
    except Exception as e:
        print("文件打開失敗,str(e)是",str(e))

#根據名稱獲取Excel表格中的數據   參數:file：Excel文件路徑     colnameindex：表頭列名所在行的所以  ，by_name：Sheet1名稱
def excel_table_byname(file= filename,colnameindex=0,by_name=u'***'):
    data = open_excel(file)
    table = data.sheet_by_name(by_name)
    nrows = table.nrows #行數
    colnames =  table.row_values(colnameindex) #某一行數據
    list =[]
    for rownum in range(1,nrows):
         row = table.row_values(rownum)
         if row:
             app = {}
             for i in range(len(colnames)):
                app[colnames[i]] = row[i]
             list.append(app)
    return list

def main():
   tables = excel_table_byindex()
   for row in tables:
       print(row)

   # tables = excel_table_byname()  #可以試試這一種
   # for row in tables:
   #     print(row)

if __name__=="__main__":
    main()
