The triplet of random letters in the 2001 format number please does permit the letter Z.
e.g. SJ12 PHZ (which is a red Skoda Fabia)

I'm new to git & python. I can try a pull request.
New line:

no_iq = string.ascii_uppercase.replace('I', '').replace('Q', '')

Edit line 105:

plate += choice(no_iq) + choice(no_iq) + choice(no_iq)
