Can I randomly generate numbers without the same number next to eachother?

My goal is to generate a series of random numbers without allowing the same number repeating next to eachother but allowing the same number twice like 1,2,1,2 but not 1,1,2,2 and I’m just not really sure how to accomplish this.

>Solution :

Something like this?

import random
list = []
list.append(random.randrange(50))
for i in range(50):
    x = random.randrange(50)
    while x == list[i]:
        x = random.randrange(50)
    list.append(x)
print(list)

Also you should post your own attempt. It gives everyone a good reference and starting point to help you out in a meaning full and focused way.
