Unit 1 Practice Solutions

Exercise 3

Problem:

print 'The last letter of 'elephant' is: {'elephant'[8]}')

Solution:

SyntaxError: Missing parentheses in call to 'print'. Did you mean print('The last letter of 'elephant' is: {'elephant'[8]}'))?

SyntaxError: invalid syntax

This problem is the same as 2., except with the next 'elephant' string. Use double quotes instead.
No error message is raised, but the output is not correct
```
The last letter of "elephant" is: {"elephant"[8]}
```
In order to have the value for "elephant"[8] print in the output, the string in the print() needs to be an f-string. Simply add a 'f' before the opening quotation mark.
IndexError: string index out of range

'Elephant' is 8 letters long, but the positions of letters in a string start at 0. Therefore, the characters in 'elephant' are 0 - 7, making the last letter of 'elephant' at position 7.

Final code:

print (f'The last letter of "elephant" is: {"elephant"[7]}')

Output:

The last letter of "elephant" is: t
