Random dictionary pick? 您应该使用对象类型而不是字符串,从 materials = ["wood", "stone", "iron"] to materials = [wood, stone, iron] 你也应该在分配这些对象之后调用它。 当使用time.sleep(random)时,Python用于循环范围 就像@user2357112supportsMonica解释的那样,每次都需要滚动它。我建议你这样做: ti...
Let’s think about a simple example where we have a set of numbers contained in a list,and we would like to pick one of those numbers uniformly at random. 在本例中,我们需要使用的函数是random.choice,在括号内,我们需要一个列表。 The function we need to use in this case is random.choice...
As you can see, this code used therandommodule and thechoice()function to choose a random element, “The Godfather” from the list. Also, you can use the followingvariations ofrandom.choice()functions to generate a random itemfrom a sequence. We will see each one of them with examples. ...
Let’s look at a diagram to clarify this idea. 我们将建立一个简单的字典,其中有与value对象关联的第一个键。 We’re going to set up a simple dictionary where we have our first key that’s associated with a value object. 我们有第二把钥匙,和另一个物体在一起。 We have our second key th...
Python中常用到随机生成的数,或者从对象中随机选择元素进行处理,random模块即可实现。 importrandomprint(random.random())#(0,1)---float 大于0且小于1之间的小数print(random.randint(1,3))#[1,3] 大于等于1且小于等于3之间的整数print(random.randrange(1,3))#[1,3) 大于等于1且小于3之间的整数print(ra...
(capitals) > 0: pick = random.choice(list(capitals.keys())) correct_answer = capitals.get(pick) print("What is the capital city of", pick, "?") answer = input("Your answer: ") if answer.lower() == correct_answer.lower(): print("That's Correct!\n") del capitals[pick] else:...
3. Pick a random project and click on it. 随机选择一个项目4. Click on the Source tab and browse through the list of files and directories until you find a .py file (but notsetup.py, that's useless). 选择源代码页,找到.py文件,注意不是setup.py,那个文件没有用5. Start at the top ...

To avoid having to rebuild the URL over and over again, you can use the params attribute to send in a dictionary of all the query parameters to append to a URL: Python >>> query_params = {"gender": "female", "nat": "de"} >>> requests.get("https://randomuser.me/api/", par...
