fname = input("Enter the file name: ")
try:
    fh = open(fname)
except:
    print("File {} cannot be opened".format(fname))
    quit()

counts = dict()
for line in fh:
    words = line.split()
# Don't need to strip() because the split() strip for us automatically, it ignores spaces at the end  
    for word in words:
        counts[word] = counts.get(word, 0) + 1

max_count = None
cword = None
for key, value in counts.items():
    if max_count is None or value > max_count:
        cword = key
        max_count = value
