Here is my example:

test = 'some string\n'
test.replace('\n',' ')
test.replace('\t',' ')

I cannot understand why output looks like

'some string\n'

'\n' should have disappeared.

`replace` doesn't replace in place. – Andrew Li Oct 06 '16 at 18:31

try `test = test.replace("\n", " ")` – lycuid Oct 06 '16 at 18:31

`replace()` returns a new string, it does not modify the existing string. – elethan Oct 06 '16 at 18:32
If I can say something - more as a tip - if u want to 'replace' tabs, enters with spaces, u can just go for `test = ' '.join('some\t test string\n'.split())` – Nf4r Oct 06 '16 at 18:34
