import time
import xlwings as xw

data = {
    ‘sheet1‘: [{
        ‘3_18‘: 2004302.0
    }, {
        ‘10_18‘: 2004406.0
    }],
    ‘sheet2‘: [{
        ‘3_10‘: 20.0
    }, {
        ‘7_10‘: 60.0
    }, {
        ‘10_10‘: 100.0
    }],
    ‘sheet3‘: [{
        ‘3_10‘: ‘jingyugushan‘
    }, {
        ‘4_10‘: ‘baguaqiankundao‘
    }]
}
# app = xw.App(visible=True, add_book=False)
# # 文件位置：filepath，新建test文档，然后保存，关闭，结束程序
# filepath = r‘xlwings_test.xlsx‘
# wb = app.books.add()
# wb.sheets[‘paybiggift‘].range(‘A1‘).value = ‘hello xlwings‘
# wb.save(filepath)
# time.sleep(8)
# wb.close()
# app.quit()

# app = xw.App(visible=True, add_book=True)
# app.display_alerts = False
# app.screen_updating = False
# 对于单元格也可以用表示行列的tuple进行引用
# A1单元格的引用
# xw.Range(1, 1)
# A1:C3单元格的引用
# xw.Range((1, 1), (3, 3))

# sht=xw.books[‘名字‘].sheets[‘名字‘]
# 在第i+1行，第j+1列的单元格
# B1单元格
# rng=sht[0,1]

def rewrite_excel(data):
    app = xw.App(visible=True, add_book=True)
    filepath = r‘test2.xlsx‘
    wb = app.books.open(filepath)
    for k, v in data.items():
        sht = wb.sheets[k]

    time.sleep(4)
    wb.save()
    wb.close()
    app.quit()

## 运行前确认test2.xlsx中存在sheet1,sheet2,sheet3
