将 multiple.txt 文件加载到 python 作为 dataframe

Question

I was struggling to load multiple.txt files in to python that are in my desktop. I am totally new to Python. My goal is to load multiple.txt files, which is saved in the same directory. The.txt files are plain texts. Thanks in advance for your help!

Answer 1

You could do something like this.

from collections import defaultdict
from pathlib import Path
import pandas as df

my_dir_path = "/parh/to/folder"

results = defaultdict(list)
for file in Path(my_dir_path).iterdir():
    with open(file, "r") as file_open:
        results["file_name"].append(file.name)
        results["text"].append(file_open.read())
df = pd.DataFrame(results)

Answer 2

This might be unnecessarily long but creates another column for the filenames, if you need:

import os
import csv
import pandas as pd
main_folder = 'path\\to\\some_folder'

def get_filename(path):
    filenames = []
    files = [i.path for i in os.scandir(path) if i.is_file()]

    for filename in files:
        filename = os.path.basename(filename)
        filenames.append(filename)
    return filenames

files = get_filename(main_folder)

with open('some.csv', 'w',  encoding = 'utf8', newline = '') as csv_file:
    for _file in files:

        file_name = _file
        with open(main_folder +'\\'+ _file,'r') as f:
            text = f.read()

            writer = csv.writer(csv_file)
            writer.writerow([file_name, text])

df = pd.read_csv('some.csv')


 # ...then whatever...

Answer 3

I would do it like this.

import glob

read_files = glob.glob('C:\\your_path_here\\*.txt')

with open('result.txt', 'wb') as outfile:
    for f in read_files:
        with open(f, 'rb') as infile:
            outfile.write(infile.read())

I have 5 text files that look like this:

FName,LName,Address
Jim,Bentz,34 Holloway La.
George,Hororitz,76 Ridge Dr.
Eric,Schimtz,11 Main St.

The final result looks like this:

FName,LName,Address
Jim,Bentz,34 Holloway La.
George,Hororitz,76 Ridge Dr.
Eric,Schimtz,11 Main St.
FName,LName,Address
Jim,Bentz,34 Holloway La.
George,Hororitz,76 Ridge Dr.
Eric,Schimtz,11 Main St.
FName,LName,Address
Jim,Bentz,34 Holloway La.
George,Hororitz,76 Ridge Dr.
Eric,Schimtz,11 Main St.
FName,LName,Address
Jim,Bentz,34 Holloway La.
George,Hororitz,76 Ridge Dr.
Eric,Schimtz,11 Main St.
FName,LName,Address
Jim,Bentz,34 Holloway La.
George,Hororitz,76 Ridge Dr.
Eric,Schimtz,11 Main St.
