concatenating character and number as one string-CodePudding

I wanna make strings like A1, A2... here is my code:

def random_room(self):
        return chr(random.randint(65, 90))   chr(random.randint(1, len(self.rooms)))

but it doesn't work

CodePudding user response：

There are better abstractions available than using chr to manipulate low-level encodings.

You want to choose a capital letter

import string
from random import choice, randint

letter = choice(string.ascii_uppercase)

and an integer

number = randint(1, len(self.rooms))

then combine them into a single string

room = f'{letter}{number}'

Put it all together:

import string
from random import choice, randint


def random_room(self):
    letter = choice(string.ascii_uppercase)
    number = randint(1, len(self.rooms))
    return f'{letter}{number}'

CodePudding user response：

I would have do something like:

def random_room(self):
        return "{}{}".format(chr(random.randint(65, 90)), random.randint(1, len(self.rooms) 1))

so you will have a random letter followed by a number between 1 and len(self.rooms)

CodePudding user response：

Use str instead of chr.

return str(random.randint(65, 90))   str(random.randint(1, len(self.rooms)))

But I think you're trying to do something like this:

letters = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
id = 0 # Your number here
number = letters[id]   str(random.randint(1, ...))
