Question

Here is the question:

I have a file with these words:

I am fine and you
Yes I am fine

And it is asked to find the numbe

Answer 1

Here i got smallest program with less memory usage for your problem

with open('FileName.txt') as f:
  lines = f.readlines()
  data = ''.join(lines)
  print('lines =',len(lines))
  print('Words = ',len(data.split()))
  data = ''.join(data.split())
  print('characters = ',len(data))

lines will be list of lines,so length of lines is nothing but number of lines.Next step data contains a string of your file contents(each word separated by a whitespace), so if we split data gives list of words in your file. thus, length of that list gives number of words. again if we join the words list you will get all characters as a single string. thus length of that gives number of characters.
