diff

I need to compare two dataframes of different size row-wise and print out non matching rows. Lets take the following two: df1 = DataFrame({ 'Buyer': ['Carl', 'Carl', 'Carl'], 'Quantity': [18, 3, 5, ]}) df2 = DataFrame({ 'Buyer': ['Carl', 'Mark', 'Carl', 'Carl'], 'Quantity': [2, 1, 18, 5]}) What is the most efficient way to row-wise over df2 and print out rows not in df1 e.g: Buyer Quantity Carl 2 Mark 1 Important: I do not want to have row: Buyer Quantity Carl 3 included in the diff: I have already tried: Comparing two dataframes of different length row by row and adding columns for each row

Someone took a version (unknown to me) of Moodle, applied many changes within a directory, and released it ( tree here ). How can I determine which commit of the original project was most likely edited to form this tree? this would allow me to form a branch at the appropriate commit with this patch. Surely it came from either the 1.8 or 1.9 branches, probably from a release tag, but diffing between particular commits doesn't help me much. Postmortem Update: knittl's answer got me as close as I'm going to get. I first added my patch repo as the remote "foreign" (no commits in common, that's OK)

I'd like to store a lot of words in a list. Many of these words are very similar. For example I have word afrykanerskojęzyczny and many of words like afrykanerskojęzycznym , afrykanerskojęzyczni , nieafrykanerskojęzyczni . What is the effective (fast and giving small diff size) solution to find difference between two strings and restore second string from the first one and diff? You can use ndiff in the difflib module to do this. It has all the information necessary to convert one string into another string. A simple example: import difflib cases=[('afrykanerskojęzyczny',

Assuming I have a text file alex bob matrix will be removed git repo and I have updated it to be alex new line here another new line bob matrix git Here, I have added lines number (2,3) and updated line number (6) How can I get these line numbers info using git diff or any other git command? git diff --stat will show you the output you get when committing stuff which is the one you are referring to I guess. git diff --stat For showing exactly the line numbers that has been changed you can use git blame -p <file> | grep "Not Committed Yet" And the line changed will be the last number before the

When I use svn diff or git diff it shows lines like: @@ -1,5 +1,9 @@ What do they mean? manojlds Those are called (c)hunk headers and contain the range information. They are surrounded by double at signs @@ . They are of the format: @@ -l,s +l,s @@ where l is the starting line number and s is the number of lines the change (c)hunk applies to for each respective file. The - indicates the original file and the + indicates the new (modified) file. Note that it not only shows affected lines, but also context lines. The -1,5 is in the original file (indicated by the - ). It shows that that first

The scenario is: svn cp or mv some file modify that file svn diff > mypatch On other machine (same working copy, but no changes): Try to apply mypatch. Fail -> tries to modify unexistant file. How can I make svn diff produce patch-appliable patch, or cleanly apply patch produced by svn diff in this case? I can't commit. I would like to preserve mergeinfo (because the obvious workaround is to add the file as totally new, without connection to the previous one). Ray With subversion, you can specify which diff binary to use, and parameters to pass to it. See the manual on svn diff. You'd want to
