python·输入多个变量

a,b,c= map(int,input('a,b,c:').split())  
a = a+1;  
b = b+2;  
c = c+3;  
print(a,b,c)  

判断一个数是否是质数

num = int(input())
if num > 1:
    for i in range(2,num):
        if (num % i) == 0:
            print("NO")
            break
    else:
        print("YES")
else:
    print("NO")

输出斐波那契数列某一序号上的数字：

n = int(input())
a=0
b=1
if (n == 0):
    print(a)
elif (n == 1):
    print(b)
else:
    if (n%2 == 0):
        for i in range(0,n-1):
            a,b = b, a+b
        print(b)
    else:
        for i in range(0,n):
            a,b = b, a+b
        print(a)
