Re: [Tutor] printing tree structure

Thanks all for the feedback. As you all rightly pointed out, I was confusing myself by not keeping a track of the recursion depth. Thanks again 2009/7/3 Alan Gauld : > > "karma" wrote > >> thinking that a recursive solution would work here, but so far I can't &g

[Tutor] printing tree structure

Hi all , I have a nested list in the structure [root,[leftSubtree],[RightSubtree]] that I want to print out. I was thinking that a recursive solution would work here, but so far I can't quite get it working. This is what I have so far: Can someone suggest whether this is suited to a recursive sol

[Tutor] Eliminating consecutive duplicates in a list

I was playing around with eliminating duplicates in a list not using groupby. From the two solutions below, which is more "pythonic". Alternative solutions would be welcome. Thanks x=[1,1,1,3,2,2,2,2,4,4] [v for i,v in enumerate(x) if x[i]!=x[i-1] or i==0] [x[i] for i in range(len(x)-1) if i==0

[Tutor] variable within function retains value

Hi All, I'm trying to write a function that flattens a list. However after I call the function more than once, it appends the result (a list) from the second call with the first. I can get around it by either setting the list to an empty one before calling the function, but I would like to keep it

Re: [Tutor] Need help solving this problem

Hi Raj, I'm another learner, I used the following: >>> def toss(n): heads = 0 for i in range(n): heads += random.randint(0,1) return heads, n-heads >>> print "%d heads, %d tails" % toss(100) Best of luck in your python endeavors! 2009/6/10 Raj Medhekar :
