Languages

• English

1. Introduction

The ord() function in Python is a built-in function used to convert a character into its corresponding Unicode (ASCII) integer value. In simple terms, it returns the numeric code representing a given character.

Every character in a computer system is stored internally as a numeric value. The ord() function helps convert that character into its Unicode code point.

2. Syntax

ord(character)

Parameter

• character A single character string whose Unicode value is required.

3. Return Value

• Returns an integer representing the Unicode code point of the given character.

4. Basic Example

print(ord('A'))

Output

65

Explanation

• The Unicode (ASCII) value of the character 'A' is 65.

5. Example with Lowercase Character

print(ord('a'))

Output

97

Explanation

• The Unicode value of 'a' is 97.

6. Example with a Digit

print(ord('5'))

Output

53

Explanation

• The character '5' has a Unicode value of 53.

7. Example with Special Character

print(ord('$'))

Output

36

Explanation

• The Unicode value of the symbol '$' is 36.

8. Example with Unicode Character

print(ord('☃'))

Output

9731

Explanation

• The Unicode value of the snowman symbol is 9731.

9. Relationship Between ord() and chr()

Example:

print(ord('A'))
print(chr(65))

Output

65
A

10. Practical Example

text = "Python"

for ch in text:
    print(ch, ord(ch))

Output

P 80
y 121
t 116
h 104
o 111
n 110

Explanation

• The program prints each character in the string along with its Unicode value.

11. Summary

• ord() is a built-in Python function used to convert a character into its Unicode integer value.
• It accepts a single character string as input.
• It returns the Unicode code point as an integer.
• It works with ASCII and Unicode characters.
• It is commonly used in character encoding and text processing.
