<while> cycle is not interrupted when using the <random>module

[ShityCoder]

Hello everyone, idea to count how many attempts module random takes before <==> to original string
unfortunatelly <while> not interrupted((((

import random

str_org = "ABC"
arr = ['A', 'B','C']
str_pat = []

for i in range(len(arr)):
    str_pat.append(random.choice(arr))

result = "".join(str_pat)

count = 0

while result != str_org:
    count += 1
    if result==str_org:
        break
    print(count)

Error:
//////////////////////
Run concole example:
56
197257
197258
197259
197260
197261
197262
......

The result string and its str_pat does not change in the while loop.
They are assigned values before the loop and from that point on never change.

You're only picking the random string once at the beginning of the program.

After you go into the while loop, result never changes, so assuming it didn't match the first time, it will never match.

Also, you don't need the separate list arr. The initial string str_org can be used as an iterator for random.choice and to tell the for loop how many times to pick.

Thank you for assistance, i solved the problem as bellow:

import random

str_org = "ABC"
arr = ['A', 'B', 'C']
str_pat = []

result=""

count = 0

while result != str_org:

    for i in range(len(arr)):
        str_pat.append(random.choice(arr))
    result = "".join(str_pat)
    count += 1
    if result==str_org:
        print(count)
        break
        
    else:
        result=""
        str_pat=[]
