一、python读取Excel

import xlrd
try:
    data = xlrd.open_workbook('source_code/CSI1k.xls')
except:
    print("fail to open file")
else:
    # 读取第一个sheet
    table = data.sheets()[0]
    # 获取行数
    n = table.nrows
    for i in range(n):
        # 取第i行第0列的值
        code = table.cell(i, 0).value
        print(code)
