Help me, please. TypeError

Question

It is from Python2
if guess < secret:
There it runs. But an error appears in Python3
TypeError: '<' not supported between instances of 'str' and 'int'
What is right in the Python3?

Answer 1

Maybe python 3 did some changes on relational operators. As the error says you are going to compare a string and a integer. The best way to overcome this problem is converting the values to a same type using int(). If you provided the full code we could help you more!

Answer 2

Line 8: guess = input( ...
guess is now a string

Line 9: if guess < secret:
Comparison between string and integer. Here is your error.

Try changing line 8:
guess = int(input( ...

Answer 3

Yes, everything works! Thanks a lot Tortello and Seniru Pasan !

Answer 4

Here is the full code. This is an example from the book about Python2

import random
secret = random.randint(1, 99)
guess = 0
tries = 0
print "Эй на палубе! Я Ужасный пират Робертс, и у меня есть секрет!"
print "Это число от 1 до 99. Я дам тебе 6 попыток."
while guess != secret and tries < 6:
guess = input("Твой вариант?")
if guess < secret:
print "Это слишком мало, презренный пес!"
elif guess > secret:
print "Это слишком много, сухопутная крыса!"
tries = tries + 1
if guess == secret:
print "Хватит! Ты угадал мой секрет!"
else:
print "Попытки кончились!"
print "Это число ", secret

And it comes out when I start the IDLE. Python 3.7.2

Эй на палубе! Я Ужасный пират Робертс, и у меня есть секрет!
Это число от 1 до 99. Я дам тебе 6 попыток.
Твой вариант 90
