Python - Read JSON - TypeError: string indices must be integers

I'm trying to read a json that I created in the script myself. When I try to access one of his "attributes" after reading the following error appears:
Traceback (most recent call last):
File "index.py", line 74, in <module>
print(json_leitura['items'])
TypeError: string indices must be integers
the same error occurs when I put it print(json_leitura['topico']) at the end.
I don't know if the creation of the JSON file is correct. I don't know if the reading is correct. When I try to trigger the "print" command or assign the value to a variable. The error described above always occurs.

The problem is in the line
arquivo_json = json.dumps(registro_json, indent=2, sort_keys=False)
Which according to the documentation, json.dumps "Serializes obj to a JSON formatted str according to conversion table"
In effect, the problem is that you are serializing the registro_json object twice, and ending up with a str. If you remove the offending line and directly pass registro_json to the gravar_arquivo_json function, everything should work.

Most of the content seems to be working fine until I get to part where I need to recommend a user identification. I'll try to work on the doc string as well in the meantime but I could totally use a little bit of help as to debug this. I tested most of the code on another .py project until I hit the function recommander
First Edit:
I did forget to apply the return. I changed it and it is now in the def. Now however...I seem to be having this error.

ValueError: 0 is not in list
Also I'm wondering about a little something. The part where I ask for an input to define id_usager in the def main(), I was wondering if there was a way to also treat characters as well as integers. Integers, I got it covered with my code but if somebody wants to write boy instead of a number, it'll fail.

accessing element of list is done by list_name[index], list_name.index(element) returns the index of that element,if they are two in the list it returns the index of the first one, if the element is not there,it throws a ValueError: "element" is not in the list.
in your case
change
usager_matrice = matrice_similarite.index(id_usager)
to
usager_matrice =matrice_similarite[id_usager]
and other places you want to access element of a list using index
in the scond question from the comment, check if its numeric like this
id_usager =input("Entrer l'ID de l'usager pour lequel vous voulez une recommandation (entre 0 et {}):".format(n))
if not id_usager.isdigit():
continue
id_user=int(id_usager)
note that this will convert also floats into int

Cant get my functions (Munt2 and Munt1) to subtract my global variable (aantal_munten)

I have a problem with my code (trying to make the NIM game with a Tkinter GUI). Anyhow i cant get my functions (Munt1, Munt2) to subtract to my global (aantal_munten). And i dont know how to fix it. Can someone point me in the right direction? Also the TKinter gui is still a bit new for me so if you have any tips or tricks for me they are well appreciated!

Python2 EOF when reading a line

everyone! I have this problem when I try to call a function that involves interaction with the user and I don't know what the problem is. The function that requires an input works perfect when separate from the other function.
I am using Jupyter Notebook [py2].
The function I am talking about is the following:
import numpy as np
import matplotlib.pyplot as plt
#Distribución Exponencial
def dist_exp():
a = int(raw_input("Ingrese Lambda: "))
b = int(raw_input("Ingrese la cantidad de numeros a generar: "))
beta = 1./a
exp = np.random.exponential((beta), b) #el primer valor es Beta (1/Lambda)
mediana_t = np.log(2)/(a*a)
print exp #imprime los números aleatorios generados
print "Estadísticos teóricos: ", "Minimo=0", " Maximo= infinito", " Media={}".format(beta), " Mediana={}".format(mediana_t), " Varianza={}".format(1/(a*a))
#imprime los estadísticos teóricos
print "Estadísticos muestrales: ", "Minimo={}".format(np.min(exp)), " Maximo={}".format(np.max(exp)), " Media={}".format(np.mean(exp)), " Mediana={}".format(np.median(exp)), " Varianza={}".format(np.var(exp))
#imprime los estadísticos muestrales
#bins son las clases para el histograma
if b<1000: #para los bins
bn = 20
else:
bn = 200
h = plt.hist(exp, bins=bn, normed=True) #bins son las clases para el histograma
plt.show() #despliega el histograma
I am calling this function (and 4 other similar functions) from the following:
from ipywidgets import widgets, interactive
from IPython.display import display
print "Ingrese la distribucion deseada. Las opciones son: Binomial, Exponencial, Geometrica, Lognormal y Triangular"
text = widgets.Text()
display(text)
def handle_submit(sender):
print(text.value)
if text.value == "Binomial":
return dist_bin()
elif text.value == "Exponencial":
return dist_exp()
elif text.value == "Geometrica":
return dist_geom()
elif text.value == "Lognormal":
return dist_log()
elif text.value == "Triangular":
return dist_tri()
else:
print "Por favor ingrese una distribucion valida. Ponga atencion a las opciones."
text.on_submit(handle_submit)
So, everytime the user types a valid String in the textbox, I need to perform a function, but I get this error instantly:
---------------------------------------------------------------------------

python 2.7 variable string to bytes savReaderWriter

I know that python 2.7 str and bytes are the same(according to Changing string to byte type in Python 2.7)
but I'm using savReaderWriter to write in a .sav file, that is, first column will be a string, and the others are numbers..
my definition is basically the same as in the documentation of savReaderWriter:
savFileName = 'someFile.sav'
records = [[b'Test1', 1, 1], [b'Test2', 2, 1]]
varNames = ['var1', 'v2', 'v3']
varTypes = {'var1': 5, 'v2': 0, 'v3': 0}
with SavWriter(savFileName, varNames, varTypes) as writer:
for record in records:
writer.writerow(record)
on this, they use b'' to convert the string to bytes, but that's a string example, that was written with the code..
but I have a list of strings strings = ["string1", "string2", ...] and each of the strings will be on the my "records"...something like this:
records = [
[strings[0], 0, 0, ...],
[strings[1], 1, 0, ...],
...
]
so, how do I convert the variable to bytes?
I'm getting 'str' object does not support item assigment
Edit: my code: and the traceback "error" that my exception generates is what i've wrote before..
def exporta_sav(matrizes, listas):
#matrizes = [matriz_grupo, matriz_n8]
#listas = [cpcs_grupo, patentes_grupo, cpcs_n8, patentes_n8]
savFile1 = "matrizgrupo.sav"
savFile2 = "matrizsubgrupo.sav"
varTypesGrupo = {}
varTypesNivel8 = {}
stringpatente = 'PATENTE'
#Cria lista auxiliar para fazer a matriz corretamente no formato .sav
varTypesGrupo[stringpatente] = 7
varTypesNivel8[stringpatente] = 7
for i in xrange(len(listas[0])):
varTypesGrupo[listas[0][i]] = 0
for i in xrange(len(listas[2])):
varTypesNivel8[listas[2][i]] = 0
cpcsGrupoAux = [stringpatente]
for i in xrange(len(listas[0])):
cpcsGrupoAux.append(listas[0][i])
cpcsN8Aux = [stringpatente]
for i in xrange(len(listas[2])):
cpcsN8Aux.append(listas[2][i])
#Com as colunas definidas, vai criar listas auxiliares para cada linha
matrizGrupoAux = []
matrizN8Aux = []
if len(matrizes[0]) == len(listas[1]):
for i in xrange(len(matrizes[0])):
matrizGrupoAux.append([ bytes(listas[1][i]) ])
for j in xrange(len(matrizes[0][i])):
matrizGrupoAux[i].append(matrizes[0][i][j])
if len(matrizes[1]) == len(listas[3]):
for i in xrange(len(matrizes[1])):
matrizN8Aux.append([ bytes(listas[3][i]) ])
for j in xrange(len(matrizes[1][i])):
matrizN8Aux[i].append(matrizes[1][i][j])
del listas
del matrizes

try:
with SavWriter(savFile1, cpcsGrupoAux, varTypesGrupo) as writer:

writer.writerows(patente)
with SavWriter(savFile2, cpcsN8Aux, varTypesNivel8) as writer:
for patente in matrizN8Aux:
writer.writerows(patente)
except Exception as error:
print("Ocorreu um erro ao escrever nos arquivos: " + str(error))
Since it's asked, the full traceback(I removed the handling):
