1.编码表：常用UTF-8、BGK

2.第一个代码：print("hello,world!")

3.if代码：

number = 50

q = input("请输入你的猜测数字：")

if q == 50:

　　print("You get the answer!")

elif q < 50:

　　print("Your number is too low.")

else q > 50:

　　print("Your number is too high.")

4.算数代码

name = input("your name:")

age = input("your age:")

OS = 80

last_year = OS - int(age)

print("There are " + str(last_year) +" years you can live.")

5.比较大小

num1 = int(input("num1>>"))

num2 = int(input("num2>>"))

num3 = int(input("num3>>"))

if num1 > num2:

　　max = num1

　　if max > num3:

　　　　print("the max number is",max)

　　else:

　　　　print("the max number is",num3)

else:

　　max = num2

　　if max > num3:

　　　　print("the max number is",max)

　　else:

　　　　print("the max number is",num3)
