Challenge: Working with Logical Operators

Uppgift

Swipe to start coding

You've been assigned a string variable t. Verify if both of these conditions are met:

The string's length is under 15 characters.
The count of the letter 'n' in this string exceeds 2.

Note

To count the number of occurrences of the letter 'n' in the string variable t, use the count method as follows: t.count('n').

You also have a numerical variable a. Determine if either of the following criteria is satisfied:

a is above 9475/37.
The remainder when dividing a by 14 is below 7.
