Python Forum - iterating through all files from a folder

Pages: 1 2

I need to write a Python program that iterates through all the data files in a folder and calculates the total number of occurrences of a given name. For example, the user would input a name, Bob, and the program has to open the folder that contains 100+ text files that contain a list of names and count every occurrence of the name 'Bob' and print the final result.

How do you work with folders in Python (I'm on a Mac)?

https://docs.python.org/3/library/pathlib.html

Pathlib is a good place to start. Something like

import pathlib

path = pathlib.Path('./data_folder')
for entry in path.iterdir():
    if entry.is_file():
        print(entry)

This is a good start thanks. Now I need to search through all of the entries for a specified name the user inputs. If I was working with only one file I would do something like this

input = 'Enter a name: '
for line in f:
     if input in line:
          print(line)

How does it work with the multiple text files in the path?

So you know how to open files, and go through them, and see all the files in the directory. So just connect the dots :p

import pathlib

path = pathlib.Path("./some_folder")
for entry in path.iterdir():
    if entry.is_file():
        with open(entry) as f:
            for line in f:
                if users_text in line:
                    print(line)

You've been a huge help! I just have one last question.

import pathlib

name = input('Enter a name: ')

path = pathlib.Path("./Names")
for entry in path.iterdir():
    if entry.is_file():
        with open(entry,'r') as f:
            for line in f:
                if name in line:
                    name_count = line.count(name)
                    print(name_count)

this program is printing a 1 for every occurrence of 'name'. What I want is to print the total number of occurrences 'name' has throughout all the files. What am I missing?

okay I was able to get a little closer to my desired end result.

import pathlib

name = input('Enter a name: ')
name_list = []

path = pathlib.Path("./Names")

for entry in path.iterdir():
    if entry.is_file():
        with open(entry,'r') as f:
            for line in f:
                if name in line:
                    name_list.append(name)
                    name_count = name_list.count(name)
                    print(name_count)

I just need the total number printed. I don't need the program to print all the counting

import os

for _, _, files in os.walk(path):
    print(files) # files is a list of all the files in path
    print('total', len(path))
    break

Then print after the loop, instead of inside it.

Sorry for all the questions. For another assignment I now need to get the number of occurrences a given name has per file. The current program finds the total occurrence in all the files together. How can I get there from my current code?

idk, what's your current code look like?
