How to convert a list into a csv file?

I'm trying to write csv file from a list:

list:

newest = ['x11;y11;z11', 'x12;y12;z12', 'x13;y13;z13', 'x14;y14;z14', 'x15;y15;z15', 'x16;y16;z16', 'x17;y17;z17', 'x18;y18;z18', 'x19;y19;z19', 'x20;y20;z20']

My actual code:

with open(r'listtocsv.csv', 'w', newline='\n') as myfile:
    wr = csv.writer(myfile, quoting=csv.QUOTE_ALL, delimiter=';')
    wr.writerow(newest)

My actual result:

Result wanted:

import csv    
newest = ['x11;y11;z11', 'x12;y12;z12', 'x13;y13;z13', 'x14;y14;z14', 'x15;y15;z15', 'x16;y16;z16', 'x17;y17;z17', 'x18;y18;z18', 'x19;y19;z19', 'x20;y20;z20']

new = []
for i in newest:
    new.append(i.split(";"))

with open("file.csv", "w", newline="") as f:
   writer = csv.writer(f)
   writer.writerows(new)

output:
