Pandas merge csv files

[karlito]

Are the separators commas?

Whatever.
You could put them together as strings.

file1 = "/path/file1.csv"
file2 = "/path/file2.csv"
outfile = "/path/all_together.csv"
all_together = ""

with open(file1, 'r') as f:
    all_together = f.read()
    
with open(file2, 'r') as f:
    all_together = f"{all_together}{f.read()}"

with open(outfile, 'w') as f:
    f.write(all_together)

yes they are commas! ok I would try your solution.
