python - Python-如何在嵌套的while循环中深入循环，以不返回到整个循环的开始，而是使其返回自己的while循环(Python - How to make a loop deep inside nested while loops to not return to the beginning of the whole loop but make it return to its own while loop)

Question

Below is my code.

(下面是我的代码。)

I used try to catch the errors when the user inputs a string instead of an integer.

(当用户输入字符串而不是整数时，我尝试捕获错误。)

It worked but for the if loops.

(它起作用，但是用于if循环。)

I want to make it so when someone enters 28 for example for the first if statement loop, it does not return to the beginning but just ask for the same question.

(我要这样做，例如，当有人在第一个if语句循环中输入28时，它不会返回到开头，而只是问相同的问题。)

So for year lets say i enter 10 it would ask again for the year again and not send the user back to the beginning or terminate the program.

(因此，对于年份，假设我输入10，它将再次要求年份，而不会将用户送回开始或终止程序。)

I am creating a project and this is the beginning of my project.

(我正在创建一个项目，这是我项目的开始。)

Also, when i try to run the code under def , without the def function, run it direcly, it gives me can not convert from str to int error meaning can not compare between the title_year column and my variable year but when i check it with df.dtype title_year column is int32 and again my year variable is an int so why can't i compare them both?

(另外，当我尝试在def下运行代码，而没有def函数时，直接运行它，这使我无法从str转换为int错误，这意味着无法在title_year列和变量year之间进行比较，但是当我使用df.dtype title_year列是int32，而我的year变量又是int，为什么我不能同时比较它们呢？)
