[MennaAssal]

I tried a lot to do this exercise ,but I have errors. Could you please help me understand what is the problem?

name = input("Enter file:") if len(name) < 1 : name = "mbox-short.txt" handle = open(name) counts=dict() for line in handle: line = line.rstrip() if line == "" : continue words = line.split() for word in words: if words[1] != "From" : continue # if words == " ":continue counts[word]=counts.get(word,0)+1 bigcounts=None bigwords=None for word,count in counts.item(): if bigcounts is None or count>bigcounts: bigwords=word bigcounts=count print(bigwords,bigcounts)
