如何制作随机电子邮件生成器？

Question

我想从我的列表中获取7个随机字母，并将其组成一个随机电子邮件，但是我无法打印出完整的电子邮件，只能一次打印出一个字母。

import random

letters = ["a", "b","c", "d","e", "f","g", "h","i", "j","k", "l","m", "n",
           "o", "p","q", "r","s", "t","u", "v","w", "x","y", "z",]

random1 = random.choice(letters)

for x in random1(7):
    print (x+"@gmail.com")

这只会给我一个错误，如果我修复它，那么我只会收到一个字母的邮件。解决方法是：

random1 = random.choice(letters)
print (random1+"@gmail.com")

请更具体和详细。哪些错误？修复它意味着什么？这似乎是一个微不足道的问题，我建议阅读以下文章：https://ericlippert.com/2014/03/05/how-to-debug-small-programs/. - AMC

Answer 1

请尝试以下方法：

import random
import string

def random_char(char_num):
       return ''.join(random.choice(string.ascii_letters) for _ in range(char_num))

print (random_char(7)+"@gmail.com")

如果您只想使用小写字母，可以使用 string.ascii_lowercase。

你不需要在这里使用变量x，可以简单地使用“_”因为没有任何东西在使用x。 - gold_cy

Answer 2

如果需要的话，您可以使用faker库来生成这个。

import faker
f = faker.Faker()

get_list_of_email(n)
    return [f.email() for _ in range(n)]

# or just print
for i in range(10):
    print(f.email()) 

这可能提供更多现实世界的测试数据

虽然可能有更高效的方法，但你可以这样做：

import itertools
import random
letters = = ["a", "b","c", "d","e", "f","g", "h","i", "j","k", "l","m", "n",
           "o", "p","q", "r","s", "t","u", "v","w", "x","y", "z",]

all_combos = list(itertools.combinations(letters,7)) #make all 7 letter combinations
all_combos = [''.join(combo) for combo in all_combos] #make them strings
email = random.sample(all_combos,1)[0]+'@gmail.com' #grab a random one, add @gmail.com

根据您最初的方法：

email = ''
for _ in range(7):
    letter = random.sample(letters,1)[0]
    email += letter

email += '@gmail.com'

尝试这个。确保“return”不在for循环中，否则它只会返回一个字母。

def random_email(char_num):
   random_email = ''
   for x in range(char_num):
       random_email+=''.join(random.choice(string.ascii_lowercase))
   return random_email


print(random_email(7) + "@gmail.com")
