Question

I’m here not with a question of specific coding, but more of a query on how to generate specific variable outputs without using if statements.

To make it clearer here is an example: Mr. Smith is giving out 5 point quizzes that are graded on a scale of 5-A, 4-B, 3-C, 2-D, 1-E, 0-F. Create a program which accepts a the quiz score (1-5) as an input and prints out the corresponding grade without using if statements.

So hopefully that makes my dilemma much clearer. I’m looking for a way to associate the grade (A-F) with the corresponding quiz score (1-5) without using an if statement. I’m still fairly new to python and you could call me a slow learner but any help is appreciated!

Answer 1

You could use:

'FEDCBA'[score]

This works by taking the character at position score in the string 'FEDCBA': F is at position 0, E is at position 1 and so on.

For example:

In [1]: 'FEDCBA'[0]
Out[1]: 'F'

In [2]: 'FEDCBA'[5]
Out[2]: 'A'
