将“for”循环的输出写入 PYTHON 中的 excel

Question

I have the following piece of code:

my_list = ["US", "IT", "ES", "NL"]
for i in my_list:
    A = sum_products_by_country(world_level,i)
    df = pd.DataFrame({'value':A})
    Descending = df.sort_values( by='value', ascending = 0 )
    Top_5 = Descending[0:5]
    print(Top_5)

The "sum_products_by_country" is a created function which takes as arguments a data frame ( in my case is named "world_level") and a country name and returns the sum by product for this country. Using this loop I find the top5 products and the sums for each country of my_list. Here is the output of this loop:

US          value
Product  


B          1492

H          455

BB         351

C          119

F          117

IT          value
Product


P           346
U           331

A           379

Q           190

D          1389

ES         value
Product 


P          3046

U3         331

A          379

Q          1390

DD         10389

NL         value
Product 


P          3465

U          3313

AA         379

2Q         190

D          189

I want to write this output in a excel sheet using :

writer = pd.ExcelWriter('top products.xlsx', engine='xlsxwriter')
Top_5.to_excel(writer, sheet_name='Sheet1')
writer.save()

Could you tell me where should I put the code above in order to get the required excel document? Is there also a way to get the column names(country,product,value) only once on the top in my excel document and not for each country separately? So I want something like this:

 Country   Product   value

  US        
           B          1492
           H          455
           BB         351
           C          119
           F          117

  IT          

           P           346
           U           331
           A           379
           Q           190
           D          1389

  ES         

          P          3046
          U3         331
          A          379
          Q          1390
          DD         10389

  NL         

          P          3465
          U          3313
          AA         379
          2Q         190
          D          189

Thank you

This script should help you:

#Create workbook object
wb = openpyxl.Workbook()
sheet = wb.get_active_sheet()
sheet.title='Products by country'

#Generate data

#Add titles in the first row of each column
sheet.cell(row=1, column=1).value='country'
sheet.cell(row=1, column=2).value='product'
sheet.cell(row=1, column=3).value='value'


#Loop to set the value of each cell
for i in range(0, len(Country)):
sheet.cell(row=i+2, column=1).value=Country[i]#with country being your array full of country names. If you have 5 values for one country I would advise just having the country name in there five times.
sheet.cell(row=i+2, column=2).value=Product[i]#array with products
sheet.cell(row=i+2, column=3).value=Values[i]#array with values

#Finally, save the file and give it a name
wb.save('NameFile.xlsx')
