对python的初步了解

python第一天总结

1. 交换值

a = 1
b = 2
a, b =b, a
print('a: ',a,'b: ',b)

2. if-else 与 if -elif

#猜拳游戏
import  random
player = input('请输入：剪刀（0），石头（1），布（2）')
player = int(player)
#生成0-2的随机整数
computer = random.randint(0, 2)#左闭右闭
if (player == 0 and computer == 2) or (player == 1 and computer == 0) or (player == 2 and computer == 1):
    print('you win')
elif player == computer:
    print('equl')
else:
    print('you lose')

3. while 循环

#九九乘法表
i = 1
while i<= 9:
    j = 1
    while j <= i:
        print('{}*{}={}'.format(j,i,j*i),end=' ')
        j += 1
    print('')
    i += 1

4. pyhton官网->docs.python.org，进入官方文档
5. 设置模板
   进入setting-->Editor-->File and Code Templates-->选择需要修改的模板
