if score[z] == maxx:
IndexError: list index out of range
You don't need "score[z]" when you do "for z in score", z is not an index, is a value of the score list.
You can just do
if z == maxx
As you delete things in a list, you end up with index problems using range(len). If you have a list and then delete an item in it, you end up with a list whose length is now one less. This leads to IndexErrors as you try to access up to the original len(list).
Perhaps think of copying the original and working with that.

I have created the matrix, but when the data entered by the user is added the board loses the initial structure
I need the board to continue printing in the same format as when the game starts.
This is the code:
tablero = []
NUM_FILAS = 6
NUM_COLUM = 7
jugador = 1
for fila in range(NUM_FILAS):
filas = []
for j in range(NUM_COLUM):
filas.append([])
tablero.append(filas)
print("\nJueguemos CONECTA 4\n")
for i in range(6):
for j in range(7):
print(tablero[i][j], end=" ")
print()
while True:
usuario = input('Jugador, elige una columna: ')
if usuario.isdigit():
usuario = int(usuario)
for pos in tablero:
if usuario == 1:
tablero.append([jugador])
print(tablero)
break
else:
print('El juego solo funciona con numeros')
My first post here, im working on a proyect and i need to append the data from CARGAR(n, vec) into the vec, i tried append but it doesnt work! I need help. Did i miss something?
I randomly select the times and i make an average called suma_t, then i make a variable called carrera with a str version of all the data.
import random
def mostrar_menu():
print("-------------------------------------------------------------------------")
print(" MENU ")
print("1. Cargar ")
print("2. Listar ")
print("-------------------------------------------------------------------------")
def validar_positivo():
n = int(input("Cuantos corredores hay?: "))
while n <= 0:
print("ERROR! Numero invalido")
return n
def cargar(n, vec):
for i in range(n):
numero = str(i+1)
nombre = str(input("Ingrese el nombre del corredor " + numero + ": "))
tiempo_1 = random.randint(0, 60)
tiempo_2 = random.randint(0, 60)
tiempo_3 = random.randint(0, 60)
suma_t = tiempo_1 + tiempo_2 + tiempo_3
tiempo_t = suma_t/3
print("Su tiempo promedio es de", tiempo_t)
carrera = str(nombre), str(tiempo_1), str(tiempo_2), str(tiempo_3), str(tiempo_t)
vec.append(carrera)
main()
def ordenar(vec):
n = len(vec)
for i in range(0, n-1):
for j in range(i+1, n):
if vec[i].tiempo_t < vec[j].tiempo_t:
vec[i], vec[j] = vec[j], vec[i]

I need no create a function that can tell if:
There´s no mode
There´s 1 mode
And if is multimodal list
I got the first 2 points cover:
lista = [1,2,2,3,3,4]
contador = {}
for i in lista:
cuenta = lista.count(i)
contador[i] = cuenta
maximo =(0)
moda = [0]
for i in contador:
if(contador[i]>maximo):
maximo = contador[i]
moda = i
freq = contador[i]
if maximo == 1:
print("There is no mode")
else:
print ("Mode is: %d, with a frequency of: %d" % (moda, freq))
But I´m struggling to find a way to define if a list is multimodal. I thought of first defining which frequency is the highest and then check contador to take out all frequencies below but it doesn´t seem to work:
for i in contador:
if contador[i] < max:
delete = [i]
del contador[delete]
Any ideas on how to do it?
Thank you
well for multimodial you need to check the max frequency and count the frequency count. if it is 1 then mean no mode, more then 1 and exactly 1 then there is 1 mode and i frequency count is more than 1 and has multiple value has same count then it is multimodial
lista = [1,2,3,3,4]
res = {}
for i in lista:
if i not in res.keys():
res[i]=1
else:
res[i]+=1
freq = res.values()
max_freq = max(freq)
if max_freq==1:
print('no mode')
else:
key = ''
if list(freq).count(max_freq)==1:
for k, v in res.items():
if v==max_freq:
print('mode is {}, frequency is {}'.format(k, max_freq))
break
else:
print('multimodeal')
for k, v in res.items():
if v==max_freq:
print('mode is {}, frequency is {}'.format(k, max_freq))
The simplest modification to your existing code would be something like:
maximo = 0
moda = []
for i in contador:
if(contador[i] > maximo):
maximo = i
freq = contador[i]
moda = []
if(contador[i]==freq):
moda.append(i)
And change the final print to:
print ("Mode is: %s, with a frequency of: %d" % (moda, freq))
The whole thing simplified with library functions:
from collections import Counter
lista = [1, 2, 2, 3, 3, 4]
contador = Counter(lista)
# get the second part (the count) from the first element of the first most common element
freq = contador.most_common(1)[0][1]
# get all the x's for which the count is freq
moda = [x for x, c in contador.items() if c == freq]
if freq == 1:
print("There is no mode")
else:
print("Mode is: %s, with a frequency of: %d" % (moda, freq))
def moda(x):
input_string = input("Lista de numeros separados por un espacio: ")
lista = input_string.split()
contador = {}
for i in lista:
cuenta = lista.count(i)
contador[i] = cuenta
maximo =(0)
for i in contador:
if(contador[i]>maximo):
maximo = contador[i]
modas = {}
for i in contador:
if contador[i] == maximo:
modas[i] = contador[i]
if maximo == 1:
return("No hay modas")
elif len(modas)>1:
return ("Las modas y sus frecuencias son:")
return (modas)
else:
return ("la moda y su frecuencia es:")
return (modas)
Sorry if my English is bad but it is not my native language
I'm starting my programming studies in Python, And I need to make this code for my class.
Basically consists of a checklist of the workers of a company to calculate their salary, applying some discounts and bonuses. In Option 4 of the menu, I must show all registered ID's with their final salary
I need to put the variable Sueldo Descontado Which is in the function Def Calcular_Sueldo() within the function Def Liquidaciones_Rut
Someone told me to define it as a class and add it to the registry List [] but I don't know how to do this :/
PS: If I define the variable SueldoDescontado as global Prints the same value for all ID's :/
I hope someone can help me
