# choice(seq)從非空序列 seq 中隨機選擇一個元素

"""  
String模組中的常量：  
string.digits：數字0~9  
string.ascii_letters：所有字母（大小寫）  
string.lowercase：所有小寫字母  
string.printable：可列印字元的字串  
string.punctuation：所有標點  
string.uppercase：所有大寫字母  
"""  
# 在指定字元中生成指定數量的隨機字元

\(mk.py\)

import random

out = open('in.txt', 'w')  
out.write(str(random.randint(-1000,1000))+'\n')

打亂陣列的順序

items = [1, 2, 3, 4, 5, 6, 7, 8, 9, 0]  
shuffle(items)  
for i in range(0, len(items)):  
    print(items[i], " ", end='')

計算時間

單位為秒

import time  
time_start = time.time()  
# 程式  
time_end = time.time()  
print(time_end-time_start)
