示例1: create_random_text

# 或者: from random import paretovariate [as 别名]
def create_random_text(strs,slen,alpha):
'''
Create strs number of strings with length of slen
Use pareto distribution to pull randomly from 4 different groups
if Alpha is large (>10) get almost 100% letters,
if Alpha is smaller (1..5) get mixture of letters, numbers and special chars
See https://en.wikipedia.org/wiki/Pareto_distribution
