random.shuffle() is the predefined way to do this. But for more general
things like this it is better to use a list to hold multiple values.
Example:
import random
picks = [] # collect unique picks
count = input("How many quick picks do you need? ")
while len(picks) < count:
pick = random.randint(1,55)
if not pick in picks:
picks.append(pick)
print picks
OR
import random
picks = [0]*55
count = input("How many quick picks do you need? ")
got = 0
while got < count:
pick = random.randint(1,55)
if not picks[pick]:
picks[pick] = 1
got += 1
for i in range(len(picks)+1):
if picks[i]:
print i,
