python操作excel初步笔记

写个python脚本， 需要读取excel里面的内容， 先记录已知笔记。

# -*- coding: utf-8 -*- 
import xdrlib, sys
import xlrd


def open_excel(file='file.xls'):
    try:
        data = xlrd.open_workbook(file)
        return data
    except Exception as e:
        print(str(e))


# 根据索引获取Excel表格中的数据   参数:file：Excel文件路径     colnameindex：表头列名所在行的所以  ，by_index：表的索引
def excel_table_byindex(file='file.xlsx', colnameindex=0, by_index=0):
    data = open_excel(file)
    table = data.sheets()[by_index]
    nrows = table.nrows  # 行数
    ncols = table.ncols  # 列数
    colnames = table.row_values(colnameindex)  # 某一行数据
    list = []
    for rownum in range(0, nrows):
        print("ij", table.cell(rownum, 0).value)
        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)


if __name__ == "__main__":
    main()
