I have a dictionary

{'12345': ['paper', '3'], '67890': ['pen', '78'], '11223': ['olive', '100'], '33344': ['book', '18']}

I need to output it to textfile like this:

12345 paper 3

67890 pen 78

11223 olive 100

33344 book 18

i tried this one:

output = open("output.txt", "w")
for k, v in dict3.items():
    output.writelines(f'{k} {v}\n')

Вut i got this:

12345 ['paper', '3']

67890 ['pen', '78']

11223 ['olive', '100']

33344 ['book', '18']

I have no idea how yo do it.How can I write a dictionary to a text file correctly?

CodePudding user response：

You can simply replace {v} with {v[0]} {v[1]}:

output = open("output.txt", "w")
for k, v in dict3.items():
    output.writelines(f'{k} {v[0]} {v[1]}\n')

If we want to write a dictionary object, we either need to convert it into string using json or serialize it. ... Write a dictionary to a file in Python

1. Import Json.
2. Create A Dictionary in-order pass it into text file.
3. Open file in write mode.
4. Use json. dumps() for json string.
