Answer 1

I think the best way to handle it would be to let one function return the word count and let the other function do something with it. No global variables needed.

Right now, your read() function returns a string which I think is rather unexpected. Either have it print the string or return the word count.

Having multiple variables access/change global variables can cause problems, especially if your program gets more complex (or you start using threads etc.)

Answer 2

Adding to Airree, here's how: define it outside functions, then inside each function add this line: global cntr

Answer 3

Exactly: cntr isn't defined. Its scope is inside the read function, so when the function finishes, it will not exist anymore. If you want it to work, you should maybe declare it in a global scope

Answer 4

Declare cntr in a global scope
