Thanks!
Scripting Index does give fairly good example
Names Default To Here(1); Hex(/* make it printable */ Blob MD5(/* get the hash */ Load Text File(/* a file from the samples */ "$SAMPLE_IMPORT_DATA/animals.txt", BLOB/* the result is a BLOB, not a string */ ) ) ) == "763D3C9F5F3E92951B3A3DC965084DAC" /* benchmark hash value */ /* the result is 1 if the benchmark matches */ ;
with slight modification
Hex(Blob MD5(Char To Blob("mytext")));
Using the Python Integration in JMP 18. The code here opens 'Big Class' adds a 'cksum' column then does the md5 checksum on the 'name' column, filling in the data table rows as you go along.
import jmp import hashlib dt = jmp.open(jmp.SAMPLE_DATA + 'Big Class.jmp') dt.new_column('cksum', jmp.DataType.Character) for x in range( dt.nrows ): dt['cksum'][x] = hashlib.md5( dt['name'][x].encode('utf-8' ) ).hexdigest()
Unfortunately, JMP 18 hasn't had a chance to be tried yet.
Looking forward to it.
Can this python code be changed from multiple lines to one line?For example:
import jmp ;import hashlib dt = jmp.open(jmp.SAMPLE_DATA + 'Big Class.jmp');dt.new_column('cksum', jmp.DataType.Character)
Thanks Experts!
Yes you can.
One of Python's central design goals is ensuring code readability. That's why there are no begin / end block control characters such as used by C / C++ / Java. { } Instead Python forces use of indentation levels to signify scoping. As a developer that has had to maintain my own code (or worse someone else's code), months or years later, I prefer making code easy for me to read. The combination on a single line only saves a single character in memory, <CRLF> vs ';' But if you have any spacing around the ';' then you are not saving memory and reducing clarity.
The choice is entirely yours.
I wish for a knowledge wiki. And a way to promote examples like this one, and make it cross-referenced by Python, MD5, and Data table.
And I like your compromise dark/light theme; between that and the drop shadow, it really looks good with the high contrast black/white.
