Merging multiple CSV files without headers being repeated (using Python)

Question

I am a beginner with Python. I have multiple CSV files (more than 10), and all of them have same number of columns. I would like to merge all of them into a single CSV file,

Your indentation is wrong, you need to put the loop inside the with block. You can also pass the file object to writer.writerows.

import csv
with open('output.csv','wb') as fout:
    wout = csv.writer(fout)
    interesting_files = glob.glob("*.csv")
    for filename in interesting_files:
        print 'Processing',filename
        with open(filename,'rb') as fin:
                next(fin) # skip header
                wout.writerows(fin)
