Getting started with Python from scratch 1

I finished studying the book "Android-The First Line of Code" during the last winter vacation. I plan to learn the language Python this winter vacation. On the one hand, I am more interested in python crawlers, and on the other hand, it is also a search. of a tool. Since I didn't find a more suitable book for beginners during this study, I just watched the python video of the Little Turtle series and felt that the effect was pretty good. Stop talking and get to the point.
Let me first briefly talk about my feelings about learning the python language (although I have learned a little knowledge). Since I have learned C, C++, Java and other languages ​​before, some grammatical structures can be said to be deeply ingrained, but python is really What's more, it doesn't take the usual path. The grammatical structure is much different from the above-mentioned languages. It feels really awkward at first. For example, python does not need to declare a variable, you can just use it if you want. Another thing is that Python does not use {} to define the scope of a function or statement, but uses indentation. The following table shows one scope for the same indentation. There are many more, which will be added slowly in the future. In short, it is still necessary It takes some time to get used to it.
First, use a simple guessing game to learn the usage of python's if statement, while statement, etc.

#编写一个猜数字的游戏，功能要求实现多次猜数，数字随机产生
#若给出的数字不是正确的答案，并给出相应的提示。
import randomprint("----------欢迎来玩我的猜数字游戏！！！---------")
print("----------你只有3次机会，一定要加油哦---------")
secret=random.randint(1,10)
temp=input("请输入你要猜的数字：")
guess=int(temp)
flag=3if (guess==secret) and (flag==3):     
print("哥，你真厉害，一次就猜对了")else:     
while (guess!=secret) and (flag!=1):
          flag=flag-1
          if guess<secret:               
print("你猜的数字小了，小了")          
if guess>secret :               
print("你猜的数字大了，大了")
          flagtostr=str(flag)          
print("你还有"+flagtostr+"次机会")
          temp=input("请重新输入你的数字:")
          guess=int(temp)     
if secret==guess :          
print("哥，你终于猜对了！！！")     
else:          
print("很抱歉，机会用完了！！！")
          secrettostr=str(secret)         
 print("正确的答案为"+secrettostr)
 print("谢谢你来玩我的小游戏！！！")

Screenshots of program running:

#The above small game is mainly to familiarize yourself with the grammatical structure of Python and understand the scope of statements controlled by Python through indentation , as well as the use of built-in functions such as input and print. Python's built-in functions will be gradually added in the future.
