python 读写excel

读取excel中的内容

def get_app_service():
    df = pd.read_excel("test.xlsx",sheet_name='test')  #读取excel对应的sheet
    data = list(df['service']) #读取一列
    # print(data)
    return data

写数据到excel，生成新的excel

writer = pd.ExcelWriter("test.xlsx")
df = pd.DataFrame(data_res) #data_res数据[[1,2,3],[1,2,3]]
df.columns = title
df.to_excel("test.xlsx",sheet_name=sheet_name,index=False)
writer.save()

写数据到已存在的excel，不生成新的excel

df = pd.DataFrame(data_res)
    df.columns = title
    file_name = 'test.xlsx'
    try:
        wb = load_workbook(file_name)
        ws = wb[sheet_name]
        wb.remove(ws)
        wb.save(file_name)
        with pd.ExcelWriter(file_name, mode='a') as writer:
            df.to_excel(writer, sheet_name=sheet_name, index=False)
    except Exception as e:
        with pd.ExcelWriter(file_name, mode='a') as writer:
            df.to_excel(writer, sheet_name=sheet_name, index=False)
