Replace list brackets in Python 3.x

Question

I have multiple list objects

Example:

data = [['id', 'host'], [1, '123']]

print(data)

Output:

[['id', 'host'], [1, '123']]

When:

print(*data)

Output:

['id', 'host'] [1, '123']

When:

print(*data, sep='
')

or

print('
'.join(map(str, data)))

Output:

['id', 'host']
[1, '123']

How to make an output like this without brackets and commas:

id host
1  123

Answer 1

A straight-forward for loop gives your desired output:

data = [['id', 'host'], [1, '123']]
for d in data:
    print(*d)

If there's a problem with that approach, it's not apparent in your question.

If you're trying to produce a str result you can use a pair of join calls to convert the inner elements to str then join with spaces, then join those lines with ' '

data = [['id', 'host'], [1, '123']]
result = '
'.join(' '.join(str(e) for e in d) for d in data)
