Underlining print message

[coolindienc]

Is there any way to underline the message I am printing? If youu see my output at the bottom I am tyring to print my message with underline. As of rightnow this is the best I came up with.

from numarray import*
 
n=input("Enter number of array elements: ")
 
a=zeros(n,Int)
b=zeros(n,Int)
 
for i in range (0,n):
    print "Enter number",i+1
    a[i]=input()
 
for i in range(0,n):
    if a[i]>0:
        b[i]=a[i]+1
 
print "Array1\tArray2"
print "______\t______"
for i in range(0,n):
    print a[i],"\t",b[i]
