python – Python substring anagram index

I am working to improve my Python skills and I have been doing a daily code problem. For the problem:

Given a word W and a string S, find all the initial indexes in S that are anagrams of W

Is there a more efficient / python solution than the code I wrote? Storing the queue as a list and converting it twice per cycle seems to be inefficient.

def anagram_indices(w, s):

  w = set(list(w))

  queue = ()
  index = ()

  for x, i in enumerate(list(s)):
    queue.append(i)

    while(w.issubset(set(queue(1:)))):
      queue.pop(0)

    if w == set(queue):
      index.append(x-1)

  return(index)

word = "ab"
string = "abxaba"

print(anagram_indices(word, string))

python 3.7 – Agenda: People Data

I am trying to schedule an agenda where I can save different information, name, surname, billing town etc …

I have been going around it but I always end up at the same point, I enter the data of the people one by one and save them in a file. I open the file and see that the data is well saved. Then to be able to modify that data, what I do is open the file and save it in a list (in this way all the modifications I will make will make them on the list and then update the file).

The problem I have is that the list is always loaded with the data of the last person in the file. I have tried the steps one by one and I am reading all the data of the people but the last one always crushes me all the previous ones.

Thank you

python: print the first 20 narcissistic numbers

My project is to generate the first 20 Armstrong numbers. I have been able to generate the numbers, but the number 370 is repeated twice.

My code is:

def print_narcissistic_nums(start, end):
for i in range(start, end + 1):
    digits = list(map(int, str(i)))
    total = 0
    length = len(digits)
    for d in digits:
        total += d ** length
        if total == i:
            print(i)

print_narcissistic_nums (0, 11000)

How to use the For loop in Python?

I want a for loop that can print the srting value if any item in the list is of string data type, how can it be possible?

I am running under the code:

mylist = (1,2,3,4,5,6,7,8,9,10,'anku','vipan')
    for hello in mylist:
        if hello % 2 ==0:
            print(f"Even number:{hello}")
        elif hello == str:
            print(f"This is string:{hello}")
        else:
            print(f"Odd Number is:{hello}")

Result that contains error

Odd Number is:1
Even number:2
Odd Number is:3
Even number:4
Odd Number is:5
Even number:6
Odd Number is:7
Even number:8
Odd Number is:9
Even number:10

Image – Cartesian Python Plans

Good evening, good afternoon and good morning. I am 15 years old and I am studying quadratic equations, Cartesian plane and functions. Because of that, I made a code to calculate the roots, the vertex coordinates, the graph and the image. The only parts I can't do are the graphic and the image that I have no idea how to do, if someone can help me, I'm very grateful. Thank you very much in advance.

follow the following code:

import math

print('-' * 30, ' Coeficientes ', '-' * 30)
valorA = int(input('Insira o coeficiente de A: '))
valorB = int(input('Insira o coeficiente de B: '))
valorC = int(input('Insira o coeficiente de C: '))

print('-' * 30, ' Raízes ', '-' * 30)
delta = math.pow(valorB, 2) - (4 * valorA * valorC)
x1 = (-valorB + math.sqrt(delta)) / 2 * valorA
x2 = (-valorB - math.sqrt(delta)) / 2 * valorA
print('Raízes: {:.0f} e {:.0f}'.format(x1, x2))

print('-' * 30, ' Coordenada das vértices ', '-' * 30)
Xv = -valorB / (2 * valorA)
Yv = valorA * math.pow(Xv, 2) + valorB * Xv + valorC
print('V({:.0f}; {:.0f})'.format(Xv, Yv))

good day
I have this code

    for aux in res:

        nombre = aux('nombre1')
        print(apellido +' '+nombre)

what I want is to save in a variable the name and surname as it shows in the for cycle, but I get this error of treceback

ramirez martha 

Traceback (most recent call last):

    apellido = aux('apellido1')

It shows me the first and last name but it tells me that I have an error in the line where I look for 'surname1'

How can I make it work correctly?

How to build a new type of syntax for an object in Python

Well, I need to build a new type of syntax that works like a string but runs the data in os.system.
The syntax should be like! Threw out! + Shell (x)
Get the data between! Y! then use it in os.system
That I have to do.

opencv – Find a specific cow in the picture frame using Python

I have trouble finding and trimming cow A in the frame of the image obtained from our CCTV camera because the barn contains many cows. Only the top views of the specific cow should be recognized. We try to match templates, but I think it does not match the project requirements. Can anyone suggest what codes in Python 3.7 we can use? Cow A is on the right side, and the other cow is on the left side, which is not necessary to recognize.
In addition, we proposed using SIFT in predictive modeling using Python 3.7 in Random Forest, knn and SVM.
This is my first time here … I hope someone helps / guides me and will really help our group for this project … Thank you.

How to use Python to mimic the Linux "su" command

I need to imitate a lot like "su" to save the user's password.

Therefore, I need the same interactive interface and the same result.

(opl@localhost)$ python su.py it is like (opl@localhost)$ su

I tried pexpect to get user input and send it, but it didn't work.

pwd=getpass.getpass("Password:")
p=pexpect.spawn("su")
p.expect("Password:",timeout=3)
p.sendline(pwd)
p.expect("(((^())*))#",timeout=3)
p.sendline("ls")

Not return anything

Is there any other way to do it?
Or did I miss something onpexpect?
