TypeError: '<=' not supported between instances of 'str' and 'int' [duplicate]

Question

I'm learning python and working on exercises. One of them is to code a voting system to select the best player between 23 players of the match using lists.

I'm using Python3.

My code:

players= [0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0] vote = 0 cont = 0  while(vote >= 0 and vote <23):     vote = input('Enter the name of the player you wish to vote for')     if (0 < vote <=24):         players[vote +1] += 1;cont +=1     else:         print('Invalid vote, try again') 

I get

TypeError: '<=' not supported between instances of 'str' and 'int'

But I don't have any strings here, all variables are integers.

Answer 1

Change

vote = input('Enter the name of the player you wish to vote for') 

to

vote = int(input('Enter the name of the player you wish to vote for')) 

You are getting the input from the console as a string, so you must cast that input string to an int object in order to do numerical operations.

Answer 2

If you're using Python3.x input will return a string,so you should use int method to convert string to integer.

Python3 Input

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.

By the way,it's a good way to use try catch if you want to convert string to int:

try:   i = int(s) except ValueError as err:   pass  

Hope this helps.
