Hello,

I have read this answer potentially as the best way to randomize a list of strings in Python. I'm just wondering then if that's the most efficient way to do it because I have a list of about 30 million elements via the following code:

import json
from sets import Set
from random import shuffle

a = []

for i in range(0,193):
    json_data = open("C:/Twitter/user/user_" + str(i) + ".json")
    data = json.load(json_data)
    for j in range(0,len(data)):
        a.append(data[j]['su'])
new = list(Set(a))
print "Cleaned length is: " + str(len(new))

## Take Cleaned List and Randomize it for Analysis
shuffle(new)

If there is a more efficient way to do it, I'd greatly appreciate any advice on how to do it.

Thanks,
