Question 2
If var = "01234567" what Python statement would print out only the even elements?
1 point
print(var[::1])print(var[::3])print(var[::2])
Solution
The correct Python statement to print out only the even elements would be:
print(var[::2])
This statement uses Python's slice syntax. Here's how it works:
- The first colon (:) means "start at the beginning".
- The second colon (:) means "go until the end".
- The 2 after the second colon means "step by 2".
So, var[::2] will start at the first element of the string (0-indexed), and then take every second element until the end of the string. This will effectively print out the characters at the even indices of the string.
