使用Python進行手機號和數字的隨機生成方法

# -*- coding:gbk -*-
import random
#隨機產生26個手機號：以13開頭，后面跟一位4~9之間的任意一位數字，后面是8位隨機數字
for _ in range(26):
 print('13' +
 str(random.randrange(4,10))+
 ''.join( str(random.choice(range(10))) for _ in range(8) )
 )
#隨機產生26個數字：產生一個0~1之間的隨機小數，乘1000,四舍五入到小數后3位，加上隨機產生的30~59之間的數字
#由于sample函數返回的結果是list類型的，這里通過[0]取出第1個值
for i in range(26):
 print( round(random.random()* 1000,3 ) + random.sample(range(30,60,3),2)[0] )

2
>>> random.randrange(1,5)
1

>>> random.choice(['a','b','c','d','e'])

>>> random.choice(['a','b','c','d','e'])
'd'
>>> random.choice(['a','b','c','d','e'])
'c'
>>> random.choice(['a','b','c','d','e'])
