Here's a simple implementation in Python that satisfies the requirements you specified:
```python
import random
def get_random_number():
return random.choice([1, 2, 3])
```
This code imports the `random` module and uses the `choice()` method to randomly select an integer from the `[1, 2, 3]` list. The function takes no inputs and always returns an integer that is either 1, 2, or 3.

def random_door(): # this method returns a random number from [1,2,3] # Parameters # there is no input # Returns # an integer, which is either 1, 2 or 3 # write your code below this line。请帮我完成需要填写的代码
```python
import random
def random_door():
return random.randint(1, 3)
```
这段代码使用了 Python 自带的 `random` 模块中的 `randint()` 函数,该函数可以返回一个指定范围内的随机整数,包括指定的上下限。在这里,我们将下限设为 1,上限设为 3,以生成一个随机的 1、2 或 3。
def monty_choice(car, contestant): # this method simulates Monty opening an door behind which there is a goat # Parameters # car, which is either 1, 2 or 3, represents the door behind which is a car # contestant, which is either 1, 2 or 3, represents the door that contestant chooses # Returns # an integer, which is 1,2 or 3, represents the door that host chooses to open # write your code below this line
Here's one possible implementation of the `monty_choice` function in Python:
```python
def monty_choice(car, contestant):
# find the door that Monty can open
options = [1, 2, 3]
options.remove(car)
if contestant in options:
options.remove(contestant)
door_to_open = random.choice(options)
return door_to_open
```
This function takes in two parameters: `car` and `contestant`, which represent the door behind which is a car and the door that the contestant chooses, respectively. It returns an integer, which represents the door that Monty chooses to open.
The function first creates a list of all possible doors (`options`) and removes the door containing the car. If the contestant has not already chosen the car door, it also removes the contestant's chosen door. The function then randomly selects one of the remaining doors to open (`door_to_open`) and returns it.
