typeerror not supported between instances of str and int что делать

Python typeerror: ‘>’ not supported between instances of ‘str’ and ‘int’ Solution

You can only compare items using mathematical operators if they have the same numerical data type. If you try to compare a string and an integer, you’ll encounter an error that says “not supported between instances of ‘str’ and ‘int’”.

In this guide, we discuss what this error means and why it is raised. We walk through an example scenario where this error is present so we can talk about how to fix it.

typeerror: ‘>’ not supported between instances of ‘str’ and ‘int’

Strings and integers cannot be compared using comparison operators. This is because strings and integers are different data types.

Python is a statically typed programming language. You have to manually change the type of a data if you need to compare it with a value of another type.

For instance, suppose you want to convert a string to an integer. You have to manually convert the string to an integer before the comparison will work.

The “typeerror: ‘>’ not supported between instances of ‘str’ and ‘int’” error occurs when you try to perform a “greater than” comparison on a string and an integer.

This error can happen with any comparison operation, such as a less than ( =).

An Example Scenario

We build a program that calculates the letter grade a student has earned in a test.

81% of participants stated they felt more confident about their tech job prospects after attending a bootcamp. Get matched to a bootcamp today.

Find Your Bootcamp Match

The average bootcamp grad spent less than six months in career transition, from starting a bootcamp to finding their first job.

Start your career switch today

To start, ask a user to insert a numerical grade which we will later convert to a letter grade using an input() statement:

Then, use an “if” statement to calculate the student’s numerical grade:

This code compares numerical_grade to a series of values. First, our code checks if numerical_grade is greater than 80. If it is, the value of “letter” becomes “A”. Otherwise, our code checks the next “elif” statement.

If the “if” and “elif” statements all evaluate to False, our code sets the value of “letter” to “F”.

At the end of our program, we print the letter grade a student has earned to the console.

Run our code and see what happens:

Our code does not run successfully. Our code asks us to insert a student grade. When our code goes to make its first comparison, an error is returned.

И опечатка: не «чило», а «число»

а вы разве говорили, что она должна заканчиваться? Вы предложили код, я его подправил, чтобы он работал.
Вот, пробуйте.

Привет! Как тебя зовут?

Просмотрите внимательно код в книге от 23 строки, у вас именно там начинается ошибка.

Там два условия сравнивания ==. Один идет в цикле for, а другой вне цикла.

Внимательно списывайте код с книги, особенно когда дойдете до игры виселица и далее. 😉

Всем доброго времени суток.
Приобрёл недавно книгу Эла Свейгарта.
И в упор не могу разобраться в чем проблема, не работает код в python 3.8, хоть ты тресни. Написанные выше коды так же не работают.
Вот мой код. Если кому не жаль, подскажите, в чем проблема, чего не понимаю?
Потому что уже неоднократно перенабирал, сверял с оригиналом, с кодами с других форумов и вопросников. И ни один так и не заработал. Сейчас выдаёт такую ошибку:
guess == int(guess)
ValueError: invalid literal for int() with base 10: ‘x’

Только,чую,не в ней одной проблема. Могу ошибаться конечно, но с оригиналом(в книге) перепроверил несколько раз, так что вроде все верно. Но в нынешних реалиях нихрена не работает Хочу разобраться и понять, в чем именно кроется подвох.

что тут не ясно? нельзя букву «х» в число превратить, не вводи х

зачем? если потом в цикле создадим ее?

в 17 строке nAmber а нужен number

покажи скрин этого кода из книги!

Подправил с nAmber на nUmber и с myName на my_name. Все заработало. Конечный код и скрин из книги прилагаю:

[Fixed] TypeError: ‘

Introduction

Problem: How to fix – TypeError: ‘ in Python?

Example:

Output:

Hence the TypeError occurred when we compared two variables whose datatypes are completely different (a string and integer in this case.)

Before proceeding further, let us have a quick look at some of the key concepts that will help you to identify and avoid TypeErrors in the future.

💡 Python TypeError

The following table lists the tenure and the corresponding Fixed Deposit rates of a certain bank.

In the following code, when the user selects a certain tenure the corresponding FD rates shall be displayed. Also, if tenure is greater than 1 year 1 day to 18 months, then customer is a “Prime Customer” else “Normal Customer”.

‘>=’ not supported between instances of ‘generator’ and ‘int’ Python Error

y’s are variables to be determined I’m trying to make loop that looks like this:

but when I try to make this as a loop: for example, like this

it gives me an error saying that

I am wondering why I get this error. When I type the indexes for each t, and type in loop indexes for y, it doesn’t give me any error but when I loop it, it gives me an error. What am I doing wrong?

It’s hard to tell what you’re asking. I think you want a list of booleans that show if the calculation is greater than or equal to 10 for each of the items in your original list. If so, you need to do that comparison within the loop, for each item, rather than for the loop as a whole. Perhaps:

However I can’t see what you’re actually doing with that generator, so I’m not sure this will help.

You probably want something like

which will give you a list of 10 True s and/or False s, named models

Don’t use a for loop, use NUMPY!

(t[i]*x + y[i,j] for j in J) is a generator. You’re also not doing anything with this comparison, you’re just throwing it into the void.

But note this is numpy (I assume, since you’re doing y[i, j] ). If you’re using a for loop you’re probably doing something wrong. Instead use numpy as it was designed. with array operations!

ta-da brand new boolean array. Here is an example:
