Int Object is not callable - manutd_to - Jul-30-2020

Hi Everyone,

I'm currently trying to make a password generator in python but I keep running into the same error. I've tried to change the function parameters to not be functions and call them first and input them as variables but I still can't get it to work.

import random
import numpy as np

upperCase = ['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M',
             'N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z']

lowerCase = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm',
              'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z',]
              
numbers = ['1', '2', '3', '4', '5', '6', '7', '8', '9', '0']

special = ['!', '@', '#','%', '^', '&', '*', '(', ')']

    
def length():
    # determins the length of password
    length = int(input("How long do you want the password to be? \n"))
    return length

def questions():
    # determines which lists to use (upperCase, lowerCase, numbers, special)
    refList = []
    uppercase = str(input("Do you want uppercase letters? \n[a] yes \n[b] no \n"))
    if uppercase == 'yes' or uppercase == 'a':
        refList.append(1)
    elif uppercase == 'no' or uppercase == 'b':
        refList.append(0)
    lowercase = str(input("Do you want lowercase letters? \n[a] yes \n[b] no \n"))
    if lowercase == 'yes' or lowercase == 'a':
            refList.append(1)
    elif lowercase == 'no' or lowercase == 'b':
        refList.append(0)
    numbers = str(input("Do you want numbers? \n[a] yes \n[b] no \n"))
    if numbers == 'yes' or numbers == 'a':
        refList.append(1)
    elif numbers == 'no' or numbers == 'b':
        refList.append(0)
    special = str(input('Do you want special characters? \n[a] yes \n[b] no \n'))
    if special == 'yes' or special == 'a':
        refList.append(1)
    elif special == 'no' or special == 'b':
        refList.append(0)
    return refList

def sumOfList(sampleList):
    # determines whether its 2 or 3 types
    total = sum(sampleList)
    return total

def determineNumbers(length, total):
    # determines the random amount of each list
    hello = length
    n = total
    rnd_array = np.random.multinomial(hello, np.ones(n)/n, size=1)[0]
    list1 = rnd_array.tolist()
    return list1


def second(refList, length):
    if refList == [0, 0, 0, 0]:
        print("Invalid answer, please try again")
            
    elif refList == [1, 0, 0, 0]:
        #JUST UPPER
        password = ''.join([random.choice(upperCase) for _ in range(length)])
        print(password)
            
    elif refList == [0, 1, 0, 0]:
        #JUST LOWER
        password = ''.join([random.choice(lowerCase) for _ in range(length)])
        print(password)
            
    elif refList == [0, 0, 1, 0]:
        #JUST NUMBERS
         password = ''.join([random.choice(numbers) for _ in range(length)])
         print(password)
            
    elif refList == [0, 0, 0, 1]:
        #JUST SPECIAL
        password = ''.join([random.choice(special) for _ in range(length)])
        print(password)
            
    elif refList == [1, 1, 0, 0]:
        #UPPER AND LOWER
        determineNumbers(length(), sumOfList(refList))
        numOfUpperCase = list1[0]
        numOfLowerCase = list1[1]
        firstpw = [random.choice(upperCase) for _ in range(numOfUpperCase)]
        secondpw = [random.choice(lowerCase) for _ in range(numOfLowercase)]
        finalpw = firstpw + secondpw
        random.shuffle(finalpw)
        new = "".join(finalpw)
        print(new)


second(questions(), length())

The error I'm getting is:
This happens when I'm trying out the [1, 1, 0, 0] case

Error:Traceback (most recent call last):

RE: Int Object is not callable - deanhystad - Jul-30-2020

length()? Where is the length() function defined?

Why are you complicating things by doing this:

Output:Do you want uppercase letters? 
[a] yes 
[b] no

Instead of

Quote:Do you want uppercase letters (y/n)?

Adding [a] and [b] makes the prompt longer, adds confusion to what you should enter ('yes' or 'a'?) and adds extra code to handle the unnecessary confusion.

RE: Int Object is not callable - manutd_to - Jul-30-2020

The length function is defined at the top, its the first function defined. Didn't realize that makes it more confusing/longer, thanks for the input, I"ll keep that in mind for next time.

RE: Int Object is not callable - perfringo - Jul-30-2020

Let Python do the typing (a.k.a. built-in module string constants):

>>> import string
>>> string.ascii_lowercase
'abcdefghijklmnopqrstuvwxyz'
>>> string.ascii_uppercase
'ABCDEFGHIJKLMNOPQRSTUVWXYZ'
>>> string.digits
'0123456789'
>>> string.punctuation
'!"#$%&\'()*+,-./:;<=>?@[\\]^_`{|}~'

But isn't length also the name of a function argument? Which do you think takes precedence, some global function outside local scope, or a local function argument?

RE: Int Object is not callable - manutd_to - Jul-30-2020

Ahh so I should change the local argument to a different name?
