How to count len() without \n?

Answer 1

Use str.strip() to remove whitespace from the string.
" test \n".strip()
results in "test"

Answer 2

OR if there are "\n" in middle of string for example:

x = "Hello \n World"

(This can't be removed by strip)

So here, use string.replace() method:

x = x.replace("\n", "")

Parameters:
x.replace(old_char, new_char)

Then len(x)
