如何在python中编写嵌套列表以表现出色？

Question

I have a nested list like:

lst = [['Fruit'], [1,2,3,4], [{'name':'banana', 'count': 3, 'color':'red'}, {'name':'apple', 'count': 12, 'color':'green'}]]

and I want to write this list to an excel file (.xlsx). My expected result is:

From here I used:

workbook = xlsxwriter.Workbook('lst.xlsx')
worksheet = workbook.add_worksheet()

lst = [['Fruit'], [1,2,3,4], [{'name':'banana', 'count': 3, 'color':'red'}, {'name':'apple', 'count': 12, 'color':'green'}]]
for i, l in enumerate(lst):
    for j, col in enumerate(l):
        worksheet.write(i, j, col)
        
workbook.close()

but it gives an error: TypeError: Unsupported type <class 'dict'> in write()

Answer 1

Try converting the elements into string before writing into the Excel sheet

for i, l in enumerate(lst):
    for j, col in enumerate(l):
        worksheet.write(i, j, str(col))

Answer 2

I finally solved the problem with:

for i in range(0, len(lst)):
    worksheet.write(0, i, ','.join([str(elem) for elem in lst[i]]))

Answer 3

Cleanest way to do so would be to use pandas:

import pandas as pd
pd.DataFrame([lst]).to_excel('excel_file.xlsx')

Answer 4

Problem Specification

You're using Nested Loop for entering your data into Excel File , So, you need to care about your data algorithm of what you're entering in case of index()

Processing The code

• Let's see how to create and write to an excel-sheet using Python. I will use your excel package not to make any confusion.

Algorithm

• You need To care about the indexing position of your data, so what we gonna do is explain how the data is entered;

• we want it to look like this:

i j lista
0 0 fruit
0 1 (1, 2, 3, 4, 5)
0 2 {'name': 'banana', 'count': 3}

In python, It should looks like this,

# I've a List of lists called `lista`:-
lista = [['Fruit'], [(1,2,3,4)], [{'name':'banana', 'count': 3, 'color':'red'}, {'name':'apple', 'count': 12, 'color':'green'}]

# By using `Nested Loop`, we can specify the entrance of the data of `lista`
for i in range(1):    # Specify any range you want
    for j in range(0, len(lista)):
        print(i, j, list[j][i])

The code:

workbook = xlsxwriter.Workbook('lst.xlsx')
worksheet = workbook.add_worksheet()

# First, to add the sec `index`, you need to add it into a `tuple`

lst = [['Fruit'], [(1,2,3,4]), [{'name':'banana', 'count': 3, 'color':'red'}, {'name':'apple', 'count': 12, 'color':'green'}]]

for i in range(1):    # Specify any range you want
    for j in range(0, len(lista)):
        worksheet.write(i, j, lista[j][i])
     
workbook.close()
