Count and print the number of words in a file

Question

I am trying to write a program that count and print the number of words in a file. The problem is that I can't use functions like split() or partition() as we don't cover them yet.

def CountWords(TextfileName)
    for 

I don't know how to start my program, can anyone explain for me a little more about reading text file?

The program should look like this:

Suppose the file some.txt contains the following:

Words make up other words. This is a line.
Sequences of words make sentences.
I like words but I don’t like MS Word.
There’s another word for how I feel about MSWord: @#%&

Then the program run produces the result shown below.

CODE: SELECT ALL
$ python3 findWord.py
Enter filename: some.txt
33 words

Answer 1

with open('some.txt') as f:
   count = len(f.read().split())
print(count)
