try:
    from urllib.parse import urlencode
except ImportError:
    from urllib import urlencode
try:
    from urllib.request import urlopen
except ImportError:
    from urllib2 import urlopen
import sys

def make_tiny(url):
    request_url = ('http://tinyurl.com/api-create.php?' + 
    urlencode({'url':url}))
    with contextlib.closing(urlopen(request_url)) as response:
        return response.read().decode('utf-8')

def main():
    for tinyurl in map(make_tiny, sys.argv[1:]):
        print(tinyurl)

random模塊可以用來選擇故事的隨機部分，內容來自每個串列里，

import random
when=['A few years ago'， 'Yesterday'， 'Last night', 'A long time ago' , 'On 20th Jan']
who=['a rabbit','an elephant', 'a mouse', 'a turtle', 'a cat']
name=[ 'Ali '，"Miriam' , "danicL','Hoouk",‘Starwalker'1
residence-[ 'Barcelona' , " India','Germany'，'Venice', 'England']
went= [ 'cinema',"university' , ' seminar', 'school'，'laundry ']
happened =['made a lot of friends' , 'Eats a burger','found a secret key', ' solved a mistery'，" wrote a book"]
print( random.choice(when) + ',' +random.choice(who) + ' that lived in ' +
random.choice(residence) +', went to the ' + random.choice(went) + ' and ' +
random.choice(happened))

email = input("what is your email address ?: ").strip()
# Slice out the user name
email = input("what is your email address ?: ").strip()
# Slice out the user name
domain_name = email[email.index("a")+1:]
#Format message
res = f"Your username is '{user_name}’ and your domain name is '{domain_name}"
# Display the result message
print(res)
--------------------------------OUTPUT------------------------------------------

import random
nunber = random.randint(1,10)
for i in range(e,3):
    user =int(input("guess the number"))
    if user -number:
       print("Hurray H")
       print(f"you guessed the number right it's {number}")
       break
    elif user>number:
       print("Your guess is too high")

import random
choices = ["Rock", "Paper", "Scissors"]
computer = random.choice(choices)
player = False
cpu_score = 0
player_score = 0
while True:
    player = input("Rock, Paper or  Scissors?").capitalize()
    # 判斷游戲者和電腦的選擇
    if player == computer:
        print("Tie!")
    elif player == "Rock":
        if computer == "Paper":
            print("You lose!", computer, "covers", player)
            cpu_score+=1
        else:
            print("You win!", player, "smashes", computer)
            player_score+=1
    elif player == "Paper":
        if computer == "Scissors":
            print("You lose!", computer, "cut", player)
            cpu_score+=1
        else:
            print("You win!", player, "covers", computer)
            player_score+=1
    elif player == "Scissors":
        if computer == "Rock":
            print("You lose...", computer, "smashes", player)
            cpu_score+=1
        else:
            print("You win!", player, "cut", computer)
            player_score+=1
    elif player=='E':
        print("Final Scores:")
        print(f"CPU:{cpu_score}")
        print(f"Plaer:{player_score}")
