chr() in Python
The chr() method returns a string representing a character whose Unicode code point is an integer.
Syntax:
chr(num) num : integer value
- The chr() method takes only one integer as argument.
- The range may vary from 0 to 1,1141,111(0x10FFFF in base 16).
- The chr() method returns a character whose unicode point is num, an integer.
- If an integer is passed that is outside the range then the method returns a ValueError.
Example: Suppose we want to print ‘G e e k s f o r G e e k s’.
# Python program to illustrate # chr() builtin function print(chr(71), chr(101), chr(101), chr(107), chr(115), chr(32), chr(102), chr(111), chr(114),chr(32), chr(71), chr(101), chr(101), chr(107), chr(115)) |

Output:
G e e k s f o r G e e k s
Another example :
# Python program to illustrate # chr() builtin function numbers = [17, 38, 79] for number in numbers: # Convert ASCII-based number to character. letter = chr(number) print("Character of ASCII value", number, "is ", letter) |

filter_none
Output:
Character of ASCII value 17 is Character of ASCII value 38 is & Character of ASCII value 79 is O
What happens if we give something out of range?
# Python program to illustrate # chr() builtin function # if value given is # out of range # Convert ASCII-based number to character print(chr(400)) |
chevron_right
filter_none
Output:
No Output
We wont get any output and the compiler will throw an error:
Traceback (most recent call last):
File "/home/484c76fb455a624cc137946a244a9aa5.py", line 1, in
print(chr(400))
UnicodeEncodeError: 'ascii' codec can't encode character
'\u0190' in position 0: ordinal not in range(128)
