Python Result Empty String. Write a Python program to get a string made of the first 2 and the last 2 chars from a given a string. Following are different ways.
Should you find yourself working with Python 2x code you might bump into a slight difference in the input functions between Python versions 2 and 3. For any non-empty string s slens-1 and s-1 both return the last character. Empty strings are falsy which means they are considered false in a Boolean context so you can just use not string.
Lets see different methods of checking if string is empty or not.
Subsequent calls to split work on the original string not on the list result of the first call to split. This will give the output. Should you find yourself working with Python 2x code you might bump into a slight difference in the input functions between Python versions 2 and 3. The secondand the mainthing you should see is that the bare split call extracts the words in the sentence and discards any whitespace.
