Python create new column in pandas df with random numbers from range

I have a pandas data frame with 50k rows. I'm trying to add a new column that is a randomly generated number from 1 to 5.

If I want 50k random numbers I'd use:

df1['randNumCol'] = random.sample(xrange(50000), len(df1))

but for this I'm not sure how to do it.

Side note in R, I'd do:

sample(1:5, 50000, replace = TRUE)

Any suggestions?
