How do i store the variable output into a list? (python)

Question

As you see that the variable 'count' has an initial value of 0. This get overwritten by the another value when the loop is ran; lets say the new value is '8'. Then as the loop runs again the new value of '8' get overwritten by the newer value; lets say the new value is '5'. This means that value '8' is unrecoverable. I do not want to lose any of the values being created from the loop, but rather store them into list. How do i store the created values into a list?

Here is my code:

def printTable(items):
    for i in  range (len(items[0])):
        print ()
        counter = 0
        for j in range(len(items)):
            if len(items[i][j]) > counter:                count = len(items[i][j])
                itemName = items[i][j]
        print ('the longest string is: ' + itemName + '; and its length is ' + str(counter))            

tableData = [['apples','oranges','cherries','banana'],
             ['Alice','Bob','Carol','David'],
             ['dogs','cats','moose','goose']]

printTable(tableData)

... have you tried looking at the documentation for lists? Or any beginner tutorials on Python? Generally, you would use .append — juanpa.arrivillaga

Make a list, and then append the value of count to it every run of the loop.

def printTable(items):
    count_list = []
    for i in  range (len(items[0])):
        print ()
        counter = 0
        for j in range(len(items)):
            if len(items[i][j]) > counter:
            count = len(items[i][j])
            count_list.append(count)
            itemName = items[i][j]
        print ('the longest string is: ' + itemName + '; and its length is ' + str(counter))
    return count_list            

tableData = [['apples','oranges','cherries','banana'],
             ['Alice','Bob','Carol','David'],
             ['dogs','cats','moose','goose']]

printTable(tableData)

I just realized the mistake i made with the 'count' and 'counter' mixing. Thank you Omegastick

Are you new to Python? There are quite a few style problems in the code. For example, we usually use snake_case for variable and function names. Variable names like count and counter are also easily confused (as you seem to have noticed). You also use a space after print, we don't usually use spaces between a function and it's parameters.
