'>' not supported between instances of 'int' and 'str'

[mp3909]

Hi,

Can someone please explain why if len(word) > col[i][1] is giving me an error saying '>' not supported between instances of 'int' and 'str'

Here is my code and the function takes this list tableData = [['apples', 'oranges', 'cherries', 'banana'],['Alice', 'Bob', 'Carol', 'David'],
['dogs', 'cats', 'moose', 'goose']] as an argument.

def myFunction(myData):
	col = [[0,0],[0,0],[0,0]]
	for i in range(len(tableData)):
		for word in tableData[i]:
			if len(word) > col[i][1]:
				col[i][1]=word
		print(col[i][1])
