Here is my idea to implement this following your %history suggestion:
1- Look in the history in the reverse order to obtain the latest entry of
the same variable assignment. Each element listed in the history output is a
separate string pulled out of a list.
2- Compare the "string".split("=") with each variable name in %whos call.
3-Write the output in the 4th column of the whos listing (using a one of the
names: "Assignment", "Command", "History"):
Variable Type Data/Info Assignment
a int 5 a=5
n float 0.0 n = math.sin(0)
Data/Info column usually produces longer lines this might cause some ugly
Could I get some suggestions?
