我尝试制作一个程序来获取一定数量的元素并随机生成它们。例如，用户可以输入20个名称并使算法随机吐出。我以这样一种方式构建程序，你最多可以输入20个元素，它会打印出这个数字加上一个随机的东西。所以你可以输入二十个元素，它会随机选择二十一个元素。问题是我不是太经验随机，所以我做得非常大（只有500行）。它有效，但我想： 1）缩短它。 2）取任何数字，而不是2到20和3）能够吐出用户输入的随机项目数。我不知道是否有任何意义，但如果可以，请帮忙！ 整个海量代码：

是的！有一个简单的方法。如果您注意到某个号码n，则会进行n操作，以便简化为循环。
import random
n = int(raw_input('Number: '))
items = raw_input('Items: ').split()
choices = [random.choice(items) for _ in xrange(n)]
print choices
我已经做到了，所以你可以一次性输入所有项目，空格作为分隔符，但这是你可以改变的。当你运行它时，你得到
Number: 5
Items: '1 4 6 56 45 34 7 12 fgtr hyt 98 0 98 78 6666666666.6'
['56', '98', "6666666666.6'", '7', 'fgtr']
现在，正如您将在许多问题中看到的那样，信任用户将给您的输入并不是一个明智的想法，因此请在try语句中包含数字的输入并根据需要重复多次，直到获得整数。
while True:
try:
n = int(raw_input('Number: '))
break
except ValueError:
print 'Gimme an integer please!'
另一件事，如果你希望你的列表包含与数字一样多的项目，你可以使用另一个循环。
items = [raw_input('Input item number {}'.format(i+1)) for i in xrange(n)]

例如
import random
a = input('Enter a number of elements(maximum twenty).\n')
if a < 2 and a > 20:
elements = []
elementsramdon = []
for x in range(a):
uservalue = raw_input('Enter the element.\n')
elements.append(uservalue) # this line contain the real values
elementsramdom.append(random.choice(uservalue)) # ramdon values
现在用于打印ramdom值
for x in elementsramdom:
print x
或者如果你想用逗号分隔[x，y，z]
print ([x for x in elementsrandom])
