Create random numbers with left skewed probability distribution

Question

I would like to pick a number randomly between 1-100 such that the probability of getting numbers 60-100 is higher than 1-59.

I would like to have the probability to be a left-skewed distribution for numbers 1-100. That is to say, it has a long tail and a peak.

Something along the lines:

pers = np.arange(1,101,1)
prob = <left-skewed distribution>
number = np.random.choice(pers, 1, p=prob)

I do not know how to generate a left-skewed discrete probability function. Any ideas? Thanks!
