Hello, I want to print list of lists in matrix format. So I use pprint
with parameter ‘width’ for this target.
For example :
>>> data=[[1, 1, 1], [1, 1, 1], [1, 1, 1]]
>>> pprint(data,width=20)
[[1, 1, 1],
[1, 1, 1],
[1, 1, 1]]
The problem that I don’t know how to select width value, because if:
>>>data=[['one', 'one', 'one'], ['one', 'one', 'one'], ['one', 'one',
'one']]
>>> pprint(data,width=20)
[['one',
'one',

1. Cpp.pprint(data, width=100)alculate a width that is big enough but
not too big. In your example, the interval is [24,69]
2. Write a loop, which gives you finer control.
>>> for line in data: print(line)
['one', 'one', 'one']
['one', 'one', 'one']
['one', 'one', 'one']
To me, this is more like a matrix and possibly better, depending on your
particular application. If the items have different default printed
widths and you want column lined up, you will need to custom format each
field in a column to a uniform width anyway. Print and pprint are for
quick, take-what-you-get output, not for customj-designed production output.
