TypeError: 'int' object is not callable, despite being a list

I was coding a linear search in Python, but it seems I got a syntax problem.

I have a function which receives an array, and inside the function I got the lenght of that array throught len function. The problem is that, despite being passing an array to the function it raises an error 'int' object is not callable.

I would highly appreciate it someone could tell me what did I did wrong and why this is happening.

I left my code below.

from random import *

def linear_search(array, value):
    for i in range(len(array)): #line where the program raises the error
        if array[i] == value:
            i = len(array)
            return 0
    return 1

n = []
len = 25

for i in range(len):
    n.append(randint(0,100))

value = n[randint(0,24)]

result = linear_search(n, value) #calling to the function

Here the working code:

from random import *

def linear_search(array, value):
    for i in range(len(array)):  # line where the program raises the error
        if array[i] == value:
            i = len(array)
            return 0
    return 1


n = []
length = 25 #renamed this from len to length

for i in range(length):  #renamed this from len to length
    n.append(randint(0, 100))

value = n[randint(0, 24)]

result = linear_search(n, value)

the code you have given had the issue that when defining this for loop:

for i in range(len):  
        n.append(randint(0, 100))

Issue: The var len is the build-in function len() and not an integer
