部分初学时练手的代码

打印世界你好！
print(num2, 'is biggest')


猜年龄

my_age= 22
a = guess_age =int(input("guess age is ;"))

c=1
while c==1:
    a = guess_age =int(input("guess age is ;"))
    if a == my_age:
        print('yes ')
        break
    elif a < my_age:
        print('try bigger')
    else :
        print('try smaller')

你还能活多久

DeathAge= 110
name = input('you name :')
a =age = input('you age :')
a = int(a)
print('Dear ',name, 'you can only live',DeathAge - a,'good luck to you ')

输出 输入长宽的#字的方体
length = int(input('length:'))
width = int (input('width:'))
a = 1
while a <= length:
    print("#",end='')
    b=0
    while b <= width :
        print('#',end="")
        b +=1
    a +=1
    print()



判断输入3个数字最大值


num1 = int(input('num1:'))
num2 = int(input('num2:'))
num3 = int(input('num3:'))
        max = num1
        if num1 > num3 :
            print(num1,'is biggest')
        else :
            print(num3,'is biggest')
    else :
        if num2 > num3:
            print(num2, 'is biggest')
        else :
            print(num3, 'is biggest')
