Python中列表中具有x个字符串的变量

有一个API。

这个 random 模块有几个选项可以从总体中选择,例如列表。如果您想对字符串结果中的每个项目使用相同的分隔符,您可以 str.join 他们

import random
my_list = ['a','b','c','d','e']
unique = " ".join(random.sample(my_list, k=2))
nonunique = " ".join(random.choices(my_list, k=2))

如果你的意思是随机选择的字符串的随机数,这可能会帮助你:

import random

my_list = ["a", "b", "c", "d", "e"]

randomCount = random.randint(0, 5)

myString = ""
for i in range(0, randomCount):
    myString = myString + " " + str(my_list[random.randint(0, 4)])

print(myString)

以下是另一种方法:

i = 0 # set i (counter to zero)
my_list = ['a','b','c','d','e'] # your list
print_str = "" # define the printed variable
for x in my_list: # loop through your list
    i += 1 # increase counter by one
    print_str += x + " " # add new strings to the printed variable
    if i == 2: # when it reach the required number of strings, breaks the loop
        break

print(print_str) # print the strings
