我正在尝试编写一个代码,该代码将在列表中随机选择1到4个元素50次。我正在使用的列表是['nu', 'ne', 'na', 'ku', 'ke', 'ka']
。
基本上,我希望它输出像
这样的东西nukuna
ke
keka
nuka
nane
nanenu
nu
nukekanu
kunu
...
50次

在Python中:
import random
input = [...] # Your input strings
output = ''
random.seed() # Seed the random generator
for i in range(0,len(input)):
N = 1+random.randrange(4) # Choose a random number between 1 and 4
for j in range(0,N): # Choose N random items out of the input
index = random.randrange(len(input)-j)
temp = input[index]
input[index] = input[len(input)-j-1]
input[len(input)-j-1] = temp
output += temp
output += ' '
print output
在C:
#include <stdlib.h>
#include <string.h>
#include <stdio.h>
#include <time.h>
char* input[NUM_OF_INPUT_STRINGS] = {...}; // Your input strings
char output[MAX_SIZE_OF_OUTPUT+1];
// Seed the random generator
srand((unsigned int)time(NULL));
for (int i=0; i<NUM_OF_INPUT_STRINGS; i++)
{
// Set the output string empty
output[0] = 0;
// Choose a random number between 1 and 4
int N = 1+(rand()%4);
// Choose N random items out of the input
for (int j=0; j<N; j++)
{
int index = rand()%(NUM_OF_INPUT_STRINGS-j);
char* temp = input[index];
input[index] = input[NUM_OF_INPUT_STRINGS-j-1];
input[NUM_OF_INPUT_STRINGS-j-1] = temp;
strcat(output,temp);
}
// Print the output
printf("%s ",output);
}

尝试使用此Python代码:
import random
my_list = ['nu', 'ne', 'na', 'ku', 'ke', 'ka']
for i in xrange(0,50):
tmp_string = ''
count = random.randrange(1,4) # choose a random between 1 and 4
for j in xrange(0, count):
# add a random member of the list to the temporary string
tmp_string = tmp_string + random.choice(my_list)
print tmp_string # print each final string

这是在python中最简单的方法
from random import randint, choice
input_list = ['nu', 'ne', 'na', 'ku', 'ke', 'ka']
for x in range(50): (print "".join([choice(input_list) for x in range(randint(1,4))]))
答案 3 :(得分:-1)
int i=0;
StringBuffer stb=new StringBuffer();
String[] arr= {"nu", "ne", "na", "ku", "ke", "ka"};
while(i<50){
int idx = new Random().nextInt(arr.length);
stb.append(arr[idx]);
i++;
}
