安装python环境

有解释器：

设置环境：

熟悉Python

var1 = 1  # 整型
var2 = 1.1  # 浮点型
var3 = 1 + 2j  # 复数
var4 = 'hello'  # 字符串
var5 = True  # 布尔型
var6 = [1, 2, 3]  # 列表List
var7 = (1, 2, 3)  # 元组Tuple
var8 = {1, 2, 3}  # 集合Set
var9 = {'name': 'Tom', 'age': 18}  # 字典Dict

# use
print(var9['name'])

# 嵌套
var9 = {'name': 'Tom', 'age': [1, 2, 3]}  # 字典Dict
print(var9)


def print_hi(name):
    print(f'Hi, {name}')  # Press Ctrl+F8 to toggle the breakpoint.
    return "nihao"


def sum_num(a, b):
    return a + b


print(print_hi('PyCharm'))
print(sum_num(1, 2))


class Person:
    def __init__(self, name, age):
        self.name = name
        self.age = age

    def print_info(self):
        print(f'Name: {self.name}, Age: {self.age}')


xiaoming = Person('小明', 18)
xiaoming.print_info()

安装torch

安装：

pip3 install torch torchvision
