I wrote this because i need to add header to every row in excel file and have
it followed by single blank row.

In pure excel this is hard to achieve without manual construction of it.

ATTENTION: I use specific encoding!!!!  UTF-8 

If you are not using utf-8 remove it from code... And be careful! 

Excel during saving as CSV UTF-8 do not use pure UTF-8!

If some problem happend - can be caused by encoding :)

#placeholder for original and new csv file
original = []
new = []

#read lines from original file
with open('csv_zoznam.csv', encoding='utf-8') as f:
    for line in f:
        original.append(line)

#create header to replicate
header = original[0]

#remove it from original and keep what "remain"
remain = original[1:]

#construct new file structure and append header, line itself and blank row for
#every row in "remain"
for line in remain:
    new.append(header)
    new.append(line)
    new.append(";;;\n")

#write it to new file
with open('csv_new.csv', mode='w', encoding='utf-8') as f:
    for line in new:
        f.write(line)
