ASCII Values of 0 to 9 in Python
In Python, each character, including numbers, has an associated ASCII (American Standard Code for Information Interchange) value. This value is a unique numerical representation of the character. Let's explore the ASCII values of numbers 0 to 9 in Python.
Understanding ASCII Values
ASCII uses a table to assign numerical values to characters. These values range from 0 to 127. Numbers 0 to 9 are represented in the ASCII table as follows:
| Character | ASCII Value |
|---|---|
| 0 | 48 |
| 1 | 49 |
| 2 | 50 |
| 3 | 51 |
| 4 | 52 |
| 5 | 53 |
| 6 | 54 |
| 7 | 55 |
| 8 | 56 |
| 9 | 57 |
Obtaining ASCII Values in Python
Python provides the built-in ord() function to get the ASCII value of a character.
Example:
print(ord('0')) # Output: 48
print(ord('9')) # Output: 57
Converting ASCII Values to Characters
Conversely, you can use the chr() function to convert an ASCII value back to its corresponding character.
Example:
print(chr(48)) # Output: 0
print(chr(57)) # Output: 9
Working with ASCII Values
Understanding ASCII values allows you to perform various tasks:
- Character Comparisons: You can compare characters by comparing their ASCII values.
- String Manipulation: You can manipulate strings by converting characters to their ASCII values and back.
- Data Encoding: ASCII values are crucial for encoding and decoding data.
Conclusion
ASCII values provide a standardized way to represent characters in computers. In Python, the ord() and chr() functions enable you to easily work with these values, allowing for various character-related operations.
