I’m doing my bachelor thesis and I need to visualize data with python / jupyter. Now I’m facing the problem that the .txt file I got is nearly executable in python but not completely.
What I’m doing now is just reading this whole file as a string and after that I manipulate is such that it is executable with exec().
Yes I now, that’s critical but since I am working on a virtual machine and I now that this data is not malicious I decided to do it like this.
The remaining problem is that I get lists like this:
sample = [[0 0 0 0 0] [0 0 0 0 0] [0 0 0 0 0] [0 0 1 0 0]]
and I need to add a comma to get a list like:
sample = [[0, 0, 0, 0, 0], [0, 0, 0, 0, 0], [0, 0, 0, 0, 0], [0, 0, 1, 0, 0]]
I found re.sub() which seems helpful but I’m wondering how.
The ‘lists’ are now stored as a string.
I would be grateful for any advice 🙂
Hints for the correct function to use or maybe the use of this function would be very helpful.
Assuming the file contents are in a string called
file_contents, you can use
file_contents = re.sub(r'](?!=])', '],', file_contents)
to add a comma after each
] not followed by another
file_contents = re.sub(r'(?<=\d) (?=\d)', ', ', file_contents)
will add commas to the spaces surrounded by digits.
