# %-10s   --- means fill in this blank with a String and force it to be 10 chars wide
#              --- the minus sign ('-') means left justify the text. So,
#                   %10s ==> Right justified
#                   %-10s ==> Left justified
# In the following string there are two placeholders that get filled in with Strings
# header1 and header2 repectively
#

for i in range(10):

    # This print statement has two placeholders also,
    # %10d ---  means fill in this blank with an integer, and force it to be 10 chars wide
    # %10.4f --- means fill in this blank with a floating point number (decimal) 10 characters
    #                  wide and with 4 numbers to the right of the decimal
    print "%-10d   %-10.4f" %(i, val2)
