okay so im making a dictionary map where it uses different symbols to refrence trees and mountains ect.
Anyways in Line 19 is where im trying to strip part of the string
the symbols are showing up as [' ▲'] instead of just ▲

import random

def createMap(size):
    m = {}
    m["grid"] = []                      
    m["size"] = size                    #map size (square) 

    #Make the empty grid
    for x in range(m["size"]):
        m["grid"].append([])           #make it a size-by-size 2D list

    #fill it with the fillCharacter
    for row in range(m["size"]):                           
        for x in range(m["size"]):
            symbolList = ["  ≈", "  ▲", "  ♣", "  ░", "  ▒"]
            weights = fillMap(row,x,m)
            weightedBiome = random.choices(symbolList, weights, k=1)
            weightedBiome[0].strip(']')
            try:
                m["grid"][row].append(weightedBiome)
            except IndexError:
                continue

#

also Is there a simple way to multiply weights with other weights?
or should i just make the weights into variables and multiply them?

#

You'd have to add the strip to be a variable, and use that variable instead

#

It won't do anything if you just use it by writing it into the code

#

!exec

txt = ".....Hello....."
txt.strip(".")
print(txt)

x = txt.strip(".")
print(x)

stray vortex !exec ```py txt = ".....Hello....." txt.strip(".") print(txt) x = txt.strip("."...

stray vortex You'd have to add the strip to be a variable, and use that variable instead

yea but here is the thing
I need to strip the weightedBiome variable that is a randomly generated choice
when i try to strip it it i get an error saying "'list' object has no atribute 'strip'"? which is strange because the weightedBiome should be the result of the randomly chosen symbol

#

i tried thius but it changes nothing

    for row in range(m["size"]):                           
        for x in range(m["size"]):
            symbolList = ["  ≈", "  ▲", "  ♣", "  ░", "  ▒"]
            weights = fillMap(row,x,m)
            weightedBiome = random.choices(symbolList, weights, k=1)
            strippedBiome = weightedBiome[0].strip('[]')
            try:
                m["grid"][row].append(weightedBiome)
            except IndexError:
                continue

#

it works but nothing is stripped

stray vortex Apr 30, 2023, 1:19 AM

#

Probably want to change the variable you append

light haven Apr 30, 2023, 1:20 AM

#

wops yea i did that i got
ValueError: The number of weights does not match the population

#

that doesnt make sense

#

im not even changing anything with the weights

stray vortex Apr 30, 2023, 1:24 AM

#

What's the full trace and error?

light haven Apr 30, 2023, 1:24 AM

#

oh sorry here

#

symbolList isn't the same length as weights list

#

weightedBiome = random.choices(symbolList, weights, k=1)

This line's causing the error

#

Check the list lengths

light haven Apr 30, 2023, 1:43 AM

#

the symbolList has 5 things in it and so do the weights no?

#

did i add an extra in one of the lists by accident?

#

i dont see any'

#

weights is equal to (1, 1, 1, 1, 1)

#

which is also 5 things in the list

stray vortex Apr 30, 2023, 1:45 AM

#

Print the variable, and check if it actually is 5 items

#

You're using a lot of += in the fillmap function

light haven Apr 30, 2023, 1:46 AM

#

oh is that not doing what i think its doing?

#

i thought it would go (1,1,1,1,1) + (1,1,1,1,1) = (2,2,2,2,2)

stray vortex Apr 30, 2023, 1:49 AM

#

!exec

x = (1, 2, 3, 4, 5)
y = (6, 7, 8, 9, 10)

x += y

print(x)

stray vortex !exec ```py x = (1, 2, 3, 4, 5) y = (6, 7, 8, 9, 10) x += y print(x) ```

(1, 2, 3, 4, 5, 6, 7, 8, 9, 10)

light haven Apr 30, 2023, 1:49 AM

#

welp yea i jsut saw it do that

#

when i printed it

#

should i make every weight a variable and add those?

#

something like this?
firstWeight = 1
secondWeight = 1
thirdWeight = 1
fourthWeight = 1
fifthWeight = 1
weights = (firstWeight,secondWeight,thirdWeight,fourthWeight,fifthWeight)

#

that looks so bad lmao

#

this does help me solve my second querstion though
