chr() Function in Python - GeeksforGeeks

Last Updated : 29 Nov, 2023

chr() function returns a string representing a character whose Unicode code point is the integer specified.

num = 97
print("ASCII Value of 97 is: ", chr(num))

ASCII Value of 97 is:  a

chr(num)

• num: an Unicode code integer

Return: Returns str

chr() function in Python is very easy to use, chr() returns string with a Unicode code equal to the integer specified. Let's look at example for better understanding.

# chr() example
print(chr(69))

Here, we are going to use Python chr() methods to get the string of Unicode.

In this example, we are printing Geeks for Geeks with the chr() in Python.

# 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))

G e e k s   f o r   G e e k s

In this example, we are Printing characters for each Unicode integer in the numbers list.

# 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)

Character of ASCII value 17 is  
Character of ASCII value 38 is  &
Character of ASCII value 79 is  O

In this example, we are printing Euro with the chr() in Python.

unicode_value = 8364
character = chr(unicode_value)
print(character) 

In this example, we are printing smiley with the chr() in Python.

unicode_value = 128516
character = chr(unicode_value)
print(character)  

In this example, we are generating a sequence of integers from 0 to 255.

unicode_values = range(256)
characters = [chr(value) for value in unicode_values]
print(characters)

['\x00', '\x01', '\x02', '\x03', '\x04', '\x05', '\x06', '\x07', '\x08', '\t', '\n', '\x0b', '\x0c', '\r', '\x0e', '\x0f', '\x10', '\x11', '\x12', '\x13', '\x14', '\x15', '\x16', '\x17', '\x18', '\x19...

# Python program to illustrate 
# chr() builtin function
# if value given is 
# out of range

# Convert ASCII-based number to character
print(chr(-400))

Output :

No Output

We won't get any output and the compiler will throw an error:

Hangup (SIGHUP)
Traceback (most recent call last):
  File "Solution.py", line 7, in <module>
    print(chr(-400))
ValueError: chr() arg not in range(0x110000)

In this article we discussed the working, uses and examples of Python chr() function. chr() function is very easy and fun to use. It is very useful when working with Unicode encoded data.

Hope you learnt about Python chr() with different examples
