將pandas的Dataframe對象讀寫Excel文件

Dataframe對象生成Excel文件 需要xlrd庫  命令  pip install xlrd

#導入pandas
import pandas as pd
import numpy as np

#導入SqlAlchemy
from sqlalchemy import create_engine

if __name__ == "__main__":
    #建立數據庫引擎
    engine = create_engine('mysql+pymysql://root:mysql@localhost:3306/mymac')
    #寫一條sql
    sql = 'select id,name,age,gender from student'
    #建立dataframe
    df = pd.read_sql_query(sql,engine)
    #導入成excel文件  參數為文件名
    df.to_excel('student.xlsx')

 

 Dataframe對象生成讀取文件 需要openpyxl庫  命令  pip install openpyxl

#導包
import pandas as pd

if __name__ == "__main__":
    #讀取數據集
    df = pd.read_excel('test.xlsx','sheet1')
    print(df)
