方法一：
import random
def phone(count):
    results = []
    while len(results)!=count:
        starts = [138,156,130,170,188,189]
        start = random.choice(starts)
        end = random.randint(0,99999999)
        res = '%s%08d\n'%(start,end)            # 格式化字串。%08d,獲取8位的數字，並換行
        if res not in results:          # 迴圈遍歷列表，不在列表中，就新增對應的號碼到列表
            results.append(res)
    with open(
 
'phone.txt','w') as fw:
        fw.writelines(results)
phone(100)

方式二：

import random
import string

def email(count):
    if count<1:
        print('count不能小於1')
        return
    emails = set()
    while len(emails)!=count:
        email_len = random.randint(6,12)
        email_end 
 
= ('@163.com', '@qq.com', '@sina.com', '@126.com')
        start = random.choice(string.ascii_uppercase)+\
        random.choice(string.ascii_lowercase)\
        + random.choice(string.digits)+random.choice(string.punctuation)
        other_len  = email_len - 4 #剩餘字串的長度
        other = random.sample(string
 
.digits+string.ascii_letters+string.punctuation,other_len)
        res = other + list(start)
        random.shuffle(res)
        end = random.choice(email_end)
        email = ''.join(res)+end+'\n'
        emails.add(email)
    with open('email.txt','w') as fw:
        fw.writelines(emails)
