Find All Files in Directory with Specific Extension

import os

target_path = 'c:\\Python38-64\DLLs'

for x in os.listdir(target_path):
    if x.endswith('.dll'):
        print(x)

This Python code imports the "os" module.

It assigns a string path 'c:\Python38-64\DLLs' to the variable "target_path". This variable represents the path of a directory that contains DLL files.

The code then uses a "for" loop to iterate over the list of items returned by the "os.listdir" method, which returns a list of all files and directories in the directory specified by "target_path". For each item in the list, the code checks if the file name ends with the extension '.dll' by using the "endswith" method.

If the file name ends with '.dll', the code prints the file name to the console using the "print" method.

So, in essence, the code is trying to find all the DLL files in the directory specified by "target_path". It does this by iterating over all the files and directories in that directory using the "os.listdir" method, and checking if each file name ends with the '.dll' extension. If the file name ends with '.dll', the code prints the file name to the console. 

import os

target_path = 'c:\\Python38-64\DLLs'

ext = input('Please enter file type: ')
for x in os.listdir(target_path):
    if x.endswith(ext):
        print(x)

The code prompts the user to enter a file type (e.g., '.txt', '.png', etc.) using the "input" function, and assigns the user input to the variable "ext".

The code then uses a "for" loop to iterate over the list of items returned by the "os.listdir" method, which returns a list of all files and directories in the directory specified by "target_path". For each item in the list, the code checks if the file name ends with the extension specified by the user input by using the "endswith" method.

If the file name ends with the specified extension, the code prints the file name to the console using the "print" method.

So, in essence, the code is trying to find all the files of a specified type in the directory specified by "target_path". It does this by prompting the user to enter a file type, and then iterating over all the files and directories in that directory using the "os.listdir" method, and checking if each file name ends with the specified file type.
