Python 随机模块方法

randint（a， b）：

返回介于 a 和 b 之间（含两者）的随机整数。如果 a > b，这也会引发 ValueError。

import random

random_int = random.randint(1,10)
print(random_int)

>>
PS \Python> python .\random_int.py
4
PS \Python> python .\random_int.py
10
PS \Python> python .\random_int.py
3

可以创建自己的模块并导入它。

#my_module.py

pi = 3.1415

#random_int.py

import random
import my_module

random_int = random.randint(1,10)
print(random_int)


print(my_module.pi)

>>
PS \Python> python .\random_int.py

3.1415

生成 Random 浮点数：

与生成整数类似，也有一些函数可以生成随机浮点序列。

• random.random（） -> 返回介于 [0.0 到 1.0] 之间的下一个随机浮点数
• random.uniform（a， b） -> 返回一个随机浮点数 N，使得 a <= N <= b 如果 a <= b，b <= N <= a 如果 b < a。
• random.随机。expovariate（lambda） -> 返回与指数分布对应的数字。
• random.gauss（mu， sigma） -> 返回与高斯分布相对应的数字。

其他分布也有类似的函数，例如 Normal Distribution、Gamma Distribution 等。

import random


random_int = random.randint(1,10)
print(random_int)

random_flot =  random.random()
print(random_flot)

项目 1：爱情评分

import random
print("\n")
print("-------Welcome to Love Calculator-------\n")

name1 =  input("What is your name?\n")
name2 =  input("What is their name?\n")

love_score =  random.randint(1, 100)

print(f"Love score of {name1} and {name2} is {love_score}")

>>

-------Welcome to Love Calculator-------

What is your name?
Lisa
What is their name?
Jack
Love score of Lisa and Jack is 34

项目 2：正面或反面

import random

random_side =  random.randint(0, 1)

if random_side == 1:
    print ("Heads")
else:
    print("Tails")

>>

PS \Python> python.exe .\heads_tails.py
Tails
PS \Python> python.exe .\heads_tails.py
Heads

列表：

检查此列表 ： 数据结构

fruits = ['orange', 'apple', 'pear', 'banana', 'kiwi', 'apple', 'banana']
print(fruits[2])
print(fruits[-2])

>>

pear
apple

fruits = ['orange', 'apple', 'pear', 'banana', 'kiwi', 'apple', 'banana']
print(fruits[2])
print(fruits[-2])

fruits[2] =  "Cheery"   #CHNAGE NAME
print(fruits)

>>

pear
apple
['orange', 'apple', 'Cheery', 'banana', 'kiwi', 'apple', 'banana']

可以将其附加到列表中：

fruits = ['orange', 'apple', 'pear', 'banana', 'kiwi', 'apple', 'banana']

fruits.append("Nid")
print(fruits)

>>
['orange', 'apple', 'pear', 'banana', 'kiwi', 'apple', 'banana', 'Nid']

扩展列表：

fruits = ['orange', 'apple', 'pear', 'banana', 'kiwi', 'apple', 'banana']

fruits.extend(["AP", "gy"])
print(fruits)

>>
['orange', 'apple', 'pear', 'banana', 'kiwi', 'apple', 'banana', 'Nid', 'AP', 'gy']    

检查列表的长度

fruits = ['orange', 'apple', 'pear', 'banana', 'kiwi', 'apple', 'banana']

print(len(fruits))

项目 3：谁来支付

names =  input("Enter the names\n")

name_list = names.split(", ")

import random

num_item = len(names)

random_choice = random.randint(0, num_item - 1)
print(names[random_choice])

嵌套列表

fruits = ['orange', 'apple', 'pear', 'banana', 'kiwi', 'apple', 'banana']
vegetables = ['Beetroot', 'Carrots', 'Capsicum', 'Ginger', 'Cauliflower']

fridge = [fruits, vegetables]
print(fridge)

>>

[['orange', 'apple', 'pear', 'banana', 'kiwi', 'apple', 'banana'], ['Beetroot', 'Carrots', 'Capsicum', 'Ginger', 'Cauliflower']]

项目 4：藏宝图

line1 = [" ", " "," "]
line2 = [" ", " "," "]
line3 = [" ", " "," "]
map = [line1, line2, line3]

print("\nHiding your treasure! X marks the spot.")
print("There are three rows and coloumes\n")


postion = input("Where do you want to put the treasure?")

letter = postion[0].lower()

abc = ["a", "b", "c"] #Possiable entry 

letter_index = abc.index(letter) 
#Checking if in "letter" (we entry), that is  there in the list or not 
#This will give us number

number_index = int(postion[1]) - 1 
#Whatever position we entered, -1 because list stars from [0]

map[number_index][letter_index] = "X"

print(f"{line1}\n{line2}\n{line3}")
   


>>


Hiding your treasure! X marks the spot.
There are three rows and coloumes

Where do you want to put the treasure?B3
[' ', ' ', ' ']
[' ', ' ', ' ']
[' ', 'X', ' ']
