Python lists

[Kieren]

I'm trying to use the following code:

counts=[]
i = stored.index(t)
counts(i) = counts(i) + 1

Where t is an integer. It is wrapped in a try block to catch if the index is out of bounds.

The error I'm getting is:

    counts(i) = counts(i) + 1
SyntaxError: can't assign to function call

I know that the error is occurring because I'm using a variable to point to the index in counts but is there a work-around for it?

From the block you've shown (As far as I can tell), counts is an array, not a function. That's why you're getting a syntax error.

In case I wasn't clear enough (I have that problem sometimes):

>>> counts = [ 1, 2, 3, 7, 9, 10 ]
>>> t = 4
>>> counts[t] = counts[t] + 1
>>> print counts[t]
10
>>>

Arg! So simple! And i've just writted a for loop to do it manually

#clear tmplist
tmplist = []
		
#loop through each index of counts
for j in range(len(counts)) :
	#check if current index = this time
	if(j==i) :
		#increment time count
		tmplist.append(counts[j]+1)
	else :
		#no match - just copy previous count
		tmplist.append(counts[j])

#copy tmplist into counts
counts = tmplist

Well.. Thanks for pointing that out! Much more efficient
