Building a string in a loop

I'm currently learning Python 3, and I have a task to: Write a program which prints out this table. (The grader will ignore spaces at the end of the line.) I'm supposed to: Focus on creating one line of the table using a loop. Think about building up a string inside the loop and then printing the string once it has all of the characters required for the one line. Then rather than using hard coded values like 32 and 48, replace the range values with variable expressions. I'm not sure where to even start.
chr: ! " # $ % & ' ( ) * + , - . /
asc: 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47
chr: 0 1 2 3 4 5 6 7 8 9 : ; < = > ?
asc: 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63
chr: @ A B C D E F G H I J K L M N O
asc: 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79
chr: P Q R S T U V W X Y Z [ \ ] ^ _
asc: 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95
chr: ` a b c d e f g h i j k l m n o
asc: 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111
chr: p q r s t u v w x y z { | } ~
asc: 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127
