Help me with my shitty code

how tf do i make a py tool that checks last 2 digits of a line in a file i provide?

with open('codes.txt', 'w') as f:
firstchar = input("18")
filedata = np.array(f)
indices = np.where(np.char.startswith(filedata, firstchar)

with open('cards_output.txt', 'w') as y:
    y.write('\n'.filedata, indices)

Do you have an example of a couple lines that would be in the file?  Is there a reason why you are using numpy arrays?  Sorry, it's kind of hard to decipher what you are trying to accomplish.

If the line always ends in digits, you could use str(var)[-2:] to get the last two digits.  For example...
 

Code:

def example(inputFile:str):
    with open(inputFile, 'r') as f:
        for line in f:
            line = line.rstrip('\n')
            lastTwo = line[-2:]
            print(f'Last Two Digits: {lastTwo} | Full Line: {line}')

def example2(inputFile:str, firstChar:str):
    for line in filter(lambda x: x.startswith(firstChar), open(inputFile,'r').readlines()):
        line = line.rstrip('\n')
        lastTwo = line[-2:]
        print(f'Last Two Digits: {lastTwo} | Full Line: {line}')
        if lastTwo.isnumeric() and lastTwo > 10:
            # do something
            pass

its alr i fixed it :

1.  
   Code:

   ids = []

with open("codes.txt","r") as fi:

    for ln in fi:
        if ln.strip().endswith("16"):
            ids.append(ln)
print(ids)

with open('codesfiltered.txt', 'w') as output_file:
    for id in ids:
        output_file.write(id)
