Why does the sys.stdout.write statement output like this?

Python Help
1 
import sys
showall = lambda x : list(map(sys.stdout.write,x))
t = showall(['spam\n','SPAM\n','Spam\n'])
print(t)

output

spam
SPAM
Spam
[5, 5, 5]

Why does the print statement output [5,5,5]?

thanks

Because sys.stdout.write returns the number of bytes it wrote?
