You could use the int() function to try to convert a line to an integer, 
and if that fails with a ValueError exception, assume that it is a name.

names=[]
numbers=[]
for line in open("mixed.txt"):
     try:
         nr=int(line)
         # it's an integer
         numbers.append(line)
     except ValueError:
         # it's not an integer
         names.append(line)

f=open("numbers.txt","wt")
f.write("".join(numbers))
f.close()

f=open("names.txt","wt")
f.write("".join(names))
f.close()
