Leockl :
How do I read in files and output the files with the same file names into another subfolder using pathlib.Path().glob()?
My directory looks like this:
New Folder 1
-> p1_a.csv
-> p1_b.csv
-> New Folder 2
Code:
from pathlib import Path
import pandas as pd
file_path = r'C:\Users\HP\Desktop\New Folder 1'
for fle in Path(file_path).glob('p1_*.csv'):
df = pd.read_csv(fle)
# do something with df
df.to_excel(file_path + r'\New Folder 2' + 'p1_*.csv' + '_new.csv')
The bit of the code which I am not sure about is 'p1_*.csv'.
After the code is run, my directory should look like this:
New Folder 1
-> p1_a.csv
-> p1_b.csv
-> New Folder 2
-> -> p1_a.csv_new.csv
-> -> p1_b.csv_new.csv
What do I need to have in the 'p1_*.csv' bit so that the new files copied in New Folder 2 has part of the same file names as the original file?
Many thanks in advance.

Try this:
import os
import pandas as pd
from pathlib import Path
source_dir = r'C:/Users/HP/Desktop/New Folder 1'
for path in Path(source_dir).glob('p1_*.csv'):
df = pd.read_csv(path)
# TODO: do something with df
filename = os.path.basename(path) #--> gets the file name
dest_path = os.path.join(source_dir, "New Folder 2", f"{filename}_new.csv")
df.to_csv(dest_path)
Now your directory structure will look like:
New Folder 1
├── New Folder 2
│ ├── p1_a.csv_new.csv
│ └── p1_b.csv_new.csv
├── p1_a.csv
└── p1_b.csv
