How to I merge multiple .txt files that are in a .zip file into only one .txt file in Python?

Question

I'm trying to merge multiple .txt files that are in a .zip file into only one .txt file in Python.

My code is the following:

firstfile = Path(r'C:\Users\Viniz\Downloads\devkmbe-5511001_05-12-2022_00_20_09.zip\AudioCaptureMemoryUsage_01_12_2022.txt')
secondfile = Path(r'C:\Users\Viniz\Downloads\devkmbe-5511001_05-12-2022_00_20_09.zip\AudioMatchingMemoryUsage_01_12_2022.txt')

newfile = input("Enter the name of the new file: ")
print()
print("The merged content of the 2 files will be in", newfile)

with open(newfile, "wb") as wfd:
    for f in [firstfile, secondfile]:
        with open(f, "rb") as fd:
            shutil.copyfileobj(fd, wfd, 1024 * 1024 * 10)

print("\nThe content is merged successfully.!")
print("Do you want to view it ? (y / n): ")

check = input()
if check == 'n':
    exit()
else:
    print()
    c = open(newfile, "r")
    print(c.read())
    c.close()

Thanks.

I tried to merge them in only one file but it doesn't worked.

To merge the files, you'll need to first extract the files from the zip file, then merge them, and then write the merged content to a new file. Here is an example of how you can do this using the zipfile module.

Update: If the .txt files are located inside a folder within the zip file, you'll need to include the folder name in the path when opening the files.

import zipfile

zip_file = r'C:\Users\Viniz\Downloads\devkmbe-5511001_05-12-2022_00_20_09.zip'
folder_name = 'myfolder'
first_file = folder_name + '/AudioCaptureMemoryUsage_01_12_2022.txt'
second_file = folder_name + '/AudioMatchingMemoryUsage_01_12_2022.txt'

with zipfile.ZipFile(zip_file, 'r') as zip_ref:
    with zip_ref.open(first_file) as f1, zip_ref.open(second_file) as f2:
        first_content = f1.read()
        second_content = f2.read()

    # Concatenate the two files
    merged_content = first_content + second_content
    
    # Write the merged content to a new file
    new_file = input("Enter the name of the new file: ")
    with open(new_file, 'wb') as new_f:
        new_f.write(merged_content)
        
    print("The content is merged successfully.!")
    print("Do you want to view it ? (y / n): ")

    check = input()
    if check == 'n':
        exit()
    else:
        print()
        c = open(new_file, "r")
        print(c.read())
        c.close()

Make sure to replace 'myfolder' with the actual name of the folder containing the .txt files in your zip file.

For multiple files..

import zipfile

zip_file = r'C:\Users\Viniz\Downloads\devkmbe-5511001_05-12-2022_00_20_09.zip'
folder_name = 'myfolder'
file_names = ['AudioCaptureMemoryUsage_01_12_2022.txt',
              'AudioMatchingMemoryUsage_01_12_2022.txt',
              'File3.txt',
              'File4.txt',
              ...
              'File29.txt']

merged_content = b''  # Initialize an empty bytes object
with zipfile.ZipFile(zip_file, 'r') as zip_ref:
    for file_name in file_names:
        with zip_ref.open(folder_name + '/' + file_name) as f:
            merged_content += f.read()
            
    # Write the merged content to a new file
    new_file = input("Enter the name of the new file: ")
    with open(new_file, 'wb') as new_f:
        new_f.write(merged_content)
        
    print("The content is merged successfully.!")
    print("Do you want to view it ? (y / n): ")

    check = input()
    if check == 'n':
        exit()
    else:
        print()
        c = open(new_file, "r")
        print(c.read())
        c.close()
