All you need to do is use item.isnumeric(). If the item made up of only numbers and not letters or other characters it will return true.

So you check the all the items in wordList and if the item isnumeric() you add the item to total.

infile = open(filename.txt, 'r')
content = infile.read()       
infile.close()

wordList = content.split()    
total = 0

for item in wordList:
    if item.isnumeric():
        total += int(item)
