I have files in a directory and i want to concatenate these files vertically to make a single file.
input
file1.txt file2.txt
1 8
2 8
3 9
i need output
1
2
3
8
8
9
My script is
import glob
import numpy as np
for files in glob.glob(*.txt):
print(files)
np.concatenate([files])
but it doesnot concatenate vertically instead it produces last file of for loop.Can anybody help.Thanks.
There's a few things wrong with your code, Numpy appears a bit overkill for such a mundane task in my opinion. You can use a much simpler approach, like for instance:
import glob
result = ""
for file_name in glob.glob("*.txt"):
with open(file_name, "r") as f:
for line in f.readlines():
result += line
print(result)
In order to save the result in a .txt-file, you could do something like:
with open("result.txt", "w") as f:
f.write(result)
This should work.
import glob
for files in glob.glob('*.txt'):
fileopen = open(r"" + files, "r+")
file_contents = fileopen.read()
output = open("output.txt", "a")
output.write(file_contents)
output.close()
