Python 3

Implement a function constantDiff() that takes a list of characters and an integer as parameters. The function returns True if the difference between the encoding of each adjacent pair of characters in the list produces a value equal to the second parameter. If there is any pair of adjacent characters in the list whose encodings do not produce the second parameters as the result when they are subtracted (ignoring the sign), the function should return False. If the function is given a list with one element, an empty list, or a negative value for the difference, the function should return False. Hint: Use an indexed loop (e.g. one that directly manipulates indices using the range() function). The following shows what the function would return for several sample executions:
