TypeError: ‘<=’ не поддерживается между экземплярами ‘str’ и ‘int’ [дубликат]
Я изучаю питон и работаю над упражнениями. Один из них — создать систему голосования для выбора лучшего игрока из 23 игроков матча с помощью списков.
Я использую Python3 .
TypeError: ‘<=’ not supported between instances of ‘str’ and ‘int’
Но у меня здесь нет никаких строк, все переменные целые числа.
Вы получаете ввод с консоли в виде строки, поэтому вы должны преобразовать эту строку ввода к int объекту, чтобы выполнять числовые операции.
Если вы используете Python3.x input вернет строку, поэтому вы должны использовать int метод для преобразования строки в целое число.
If the prompt argument is present, it is written to standard output without a trailing newline. The function then reads a line from input, converts it to a string (stripping a trailing newline), and returns that. When EOF is read, EOFError is raised.
Кстати, это хороший способ использовать, try catch если вы хотите преобразовать строку в int:
[Solved] typeerror: ‘ 1. Producing the error
If you look at the above code, we are trying to grade students based on the input of a user. If you check the output, the error is present since we are trying to compare grade which is expecting a data type of integer value and user input has a string value. When comparing these two values to determine a student’s grade, the error occurs because the program cannot compare a string data type and integer data type. Now that we have TypeError: ‘<‘ not supported between instances of ‘str’ and ‘int’ in our code, let’s look at the next section on how to solve this error.
1. Solution
To solve the type error, we will use the int() method.
1. Using int() method
Output:
Enter Students overall score: 80
First class
Explanation:
In the above code, we can see that we have used the int() method. This method converts user input which is a string data type into an integer data type, hence comparison can be made with comparison operators such as (<).
2. Producing the error
This error occurs when we try to compare two variables of different data types. Here, we are performing a comparison between integers and a String value.
Output:
Traceback (most recent call last):
File «<string>», line 1, in <module>
TypeError: ‘<‘ not supported between instances of ‘str’ and ‘int’
Explanation:
2. Solution
To solve this error we will replace the string with integer as shown below:
Output:
The min is: 1
Explanation:
Here, min() function passed all integer arguments (1, 23, 7, 19) without any string values. As a result, the min() function is able to compare and find the smallest value among the integers. Hence, we got the output as 1.
That’s all for today. Please mention in the comments in case you have any questions related to typeerror: ‘<‘ not supported between instances of ‘str’ and ‘int’.
