Python Program to Print ASCII values of Alphabets

In this article, we will learn about python program to print ASCII values of alphabets. In other words, we will learn to print ASCII values of all letters of alphabets from a to z to A to Z i.e. in lowercase and uppercase both.

Getting Started

The task is to print ASCII value of alphabets in lowercase or uppercase.

Alphabets in Lowercase – 

a b c d e f g h i j k l m n o p q r s t u v w x y z

Alphabets in Uppercase – 

A B C D E F G H I J K L M O P N Q R S T U V W X Y Z

We have to print ASCII values of each letters of alphabets shown above.

We can do so in below ways –

Using Hardcoded String Values

We know that there are total 26 letters of alphabets. It won’t change. So, we can use below algorithm to print ASCII values of each letter in alphabet

Pseudo Algorithm

  • Store the alphabets as string in a variable.
  • Iterate over string.
  • In each iteration, get ASCII value using ord() function and print it using print() function.

  • Print ASCII values of Alphabets in Lowercase

    Store all lowercase alphabets in variable and print ascii values as shown below – 

    alphabets = "abcdefghijklmnopqrstuvwxyz"
for ch in alphabets:
    print("Character: " + ch + ", ASCII Value: ", ord(ch))

    Output: 

     
Character: a, ASCII Value:  97
Character: b, ASCII Value:  98
Character: c, ASCII Value:  99
Character: d, ASCII Value:  100
Character: e, ASCII Value:  101
Character: f, ASCII Value:  102
Character: g, ASCII Value:  103
Character: h, ASCII Value:  104
Character: i, ASCII Value:  105
Character: j, ASCII Value:  106
Character: k, ASCII Value:  107
Character: l, ASCII Value:  108
Character: m, ASCII Value:  109
Character: n, ASCII Value:  110
Character: o, ASCII Value:  111
Character: p, ASCII Value:  112
Character: q, ASCII Value:  113
Character: r, ASCII Value:  114
Character: s, ASCII Value:  115
Character: t, ASCII Value:  116
Character: u, ASCII Value:  117
Character: v, ASCII Value:  118
Character: w, ASCII Value:  119
Character: x, ASCII Value:  120
Character: y, ASCII Value:  121
Character: z, ASCII Value:  122

  • Print ASCII values of Alphabets in Uppercase

    Like lowercase alphabets, store uppercase alphabets in variable and iterate over it. For example,

     
alphabets = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
for ch in alphabets:
    print("Character: " + ch + ", ASCII Value: ", ord(ch))

    Output: 

     
Character: A, ASCII Value:  65
Character: B, ASCII Value:  66
Character: C, ASCII Value:  67
Character: D, ASCII Value:  68
Character: E, ASCII Value:  69
Character: F, ASCII Value:  70
Character: G, ASCII Value:  71
Character: H, ASCII Value:  72
Character: I, ASCII Value:  73
Character: J, ASCII Value:  74
Character: K, ASCII Value:  75
Character: L, ASCII Value:  76
Character: M, ASCII Value:  77
Character: N, ASCII Value:  78
Character: O, ASCII Value:  79
Character: P, ASCII Value:  80
Character: Q, ASCII Value:  81
Character: R, ASCII Value:  82
Character: S, ASCII Value:  83
Character: T, ASCII Value:  84
Character: U, ASCII Value:  85
Character: V, ASCII Value:  86
Character: W, ASCII Value:  87
Character: X, ASCII Value:  88
Character: Y, ASCII Value:  89
Character: Z, ASCII Value:  90

Using string.ascii_lowercase or string.ascii_uppercase

In previous codes, we hardcoded all alphabets and stored in a variable. If we don’t want to hardcode it, we can either string constants – string.ascii_lowercase or string.ascii_uppercase to get alphabets in lowercase and uppercase respectively.

Pseudo Algorithm

  • Store value returned by string.ascii_lowercase or string.ascii_uppercase in a variable.
  • Then, run a for loop on returned values.
  • In each iteration, get ASCII value of character using ord() function and print it using print() function.

  • Print ASCII values using string.ascii_lowercase

    string.ascii_lowercase returns alphabets in lowercase. So, we can print ascii values of alphabets as shown below – 

    import string
alphabets = string.ascii_lowercase
for ch in alphabets:
    print("Character: " + ch + ", ASCII Value: ", ord(ch))

    Output:

    Character: a, ASCII Value:  97
Character: b, ASCII Value:  98
Character: c, ASCII Value:  99
Character: d, ASCII Value:  100
Character: e, ASCII Value:  101
Character: f, ASCII Value:  102
Character: g, ASCII Value:  103
Character: h, ASCII Value:  104
Character: i, ASCII Value:  105
Character: j, ASCII Value:  106
Character: k, ASCII Value:  107
Character: l, ASCII Value:  108
Character: m, ASCII Value:  109
Character: n, ASCII Value:  110
Character: o, ASCII Value:  111
Character: p, ASCII Value:  112
Character: q, ASCII Value:  113
Character: r, ASCII Value:  114
Character: s, ASCII Value:  115
Character: t, ASCII Value:  116
Character: u, ASCII Value:  117
Character: v, ASCII Value:  118
Character: w, ASCII Value:  119
Character: x, ASCII Value:  120
Character: y, ASCII Value:  121
Character: z, ASCII Value:  122

  • Print ASCII values using string.ascii_uppercase

    string.ascii_uppercase returns alphabets in Uppercase. So, we can write python program to print ascii values of alphabets as shown below – 

    import string
alphabets = string.ascii_uppercase
for ch in alphabets:
    print("Character: " + ch + ", ASCII Value: ", ord(ch))

    Output: 

     
Character: A, ASCII Value:  65
Character: B, ASCII Value:  66
Character: C, ASCII Value:  67
Character: D, ASCII Value:  68
Character: E, ASCII Value:  69
Character: F, ASCII Value:  70
Character: G, ASCII Value:  71
Character: H, ASCII Value:  72
Character: I, ASCII Value:  73
Character: J, ASCII Value:  74
Character: K, ASCII Value:  75
Character: L, ASCII Value:  76
Character: M, ASCII Value:  77
Character: N, ASCII Value:  78
Character: O, ASCII Value:  79
Character: P, ASCII Value:  80
Character: Q, ASCII Value:  81
Character: R, ASCII Value:  82
Character: S, ASCII Value:  83
Character: T, ASCII Value:  84
Character: U, ASCII Value:  85
Character: V, ASCII Value:  86
Character: W, ASCII Value:  87
Character: X, ASCII Value:  88
Character: Y, ASCII Value:  89
Character: Z, ASCII Value:  90

That’s how we can write python program to print ASCII values of alphabets.
