在学习python之前一直纠结要不要学,之前会一点java,语言在精,不再多。学习python会不会是在浪费时间,但网上一句“人生苦短,我用python”,又激起了我学习python的兴趣,下面是我学习python第一天的内容,以博客文章的形式记录学习过程中的 点点滴滴.........
1.开始写python代码前在python 2.xx中必写的两句话,python 3.xx不用
#!usr/bin/env python
#_*_ conding:utf-8 _*_
2.变量---保存存储值的内存位置
(1)声明变量
num = 1
变量名:num
变量值:1
=:是赋值的意思,不是相等
注:python是动态语言,不必考虑数据类型,查看数据类型用type,例如:
print(type(num))
3.if,if...elif循环
guess_num_game ==66
guess_num = int(input("guess_num:"))
if guess_num == guess_num_game:
print("恭喜你,才对了")
break
elif guess_num>guess_num_gane:
print("再小一点")
else:
print("再大一点")3.while
guess_num_game ==66
count = 0while count < 3:4.for循环guess_num = int(input("guess_num:"))
if guess_num == guess_num_game: print("恭喜你,才对了") breakelif guess_num>guess_num_gane: print("再小一点")else: print("再大一点")
count +=1else: print("不好意思,您的机会已经用完,请下次再猜")guess_num_game ==66
for i in range(3): guess_num = int(input("guess_num:"))if guess_num == guess_num_game:
else:
print("恭喜你,才对了")
break
elif guess_num>guess_num_gane:
print("再小一点")
else:
print("再大一点")print("不好意思,您的机会已经用完,请下次再猜")
5.任意猜数字
guess_num_game = 66count =0while count < 3: guess_age = int(input("guess_age:"))if guess_num == guess_num_game:
count +=1
print("恭喜你,才对了")
break
elif guess_num>guess_num_gane:
print("再小一点")
else:
print("再大一点")if count ==3:
countine = int(input("你想继续猜吗...? 1:继续 2:退出:"))
if countine ==1:
count = 0
else:
print("游戏结束,退出")
break
else:print("不好意思,您的机会已经用完,请下次再猜")
