Rock, Paper, Scissors in Python
There is much to improve. I recommend you read PEP 8, the official Python style guide. It includes many important tips like:


Use consistent 4-space indentation
Multiple statements on the same line are discouraged


Furthermore:


You should use words instead of single letters for your variable names. All those variables like x, l, w, d, lt, wt, dt aren't self-explaining. What is their purpose? Instead: count_rounds, count_losses, count_wins, count_draws, ….
Your usage of object oriented features is extremely weird. Get rid of all classes for now.
Instead of x = x + 1 write x += 1.
Your code is really complicated because it munges together the user interface (prompting the user for choices, displaying results) with the actual logic of your program. Put the logic into separate functions, e.g.

def beats(choice_a, choice_b):
    if choice_a == 'rock' and choice_b == 'scissors':
        return 'smashes'
    if choice_a == 'scissors' and choice_b == 'paper':
        return 'cuts'
    if choice_a == 'paper' and choice_b == 'rock':
        return 'wraps'
    else:
        return None


This could be used as

def result_string(computer, player):
    verb = beats(computer, player)
    if verb:
        return "computer beats player because %s %s %s" % (computer, verb, player)
    verb = beats(player, computer)
    if verb:
        return "player beats computer because %s %s %s" % (player, verb, computer)
    return "draw"


which in turn could be used as print(result_string(computer_choice, player_choice)).


Please try to fix these issues and to clean up your code, then come back and ask a new question for a second round of review.
