Course Overview
Python chr() Function
Python chr() function is used to get a string representing of a character which points to a Unicode code integer. For example, chr(97) returns the string ‘a’. This function takes an integer argument and throws an error if it exceeds from the specified range. The standard range of the argument is from 0 to 1,114,111.
Signature
- chr(i)
Parameters
i: It is an integer value.
Return
This function returns a string representation of a character.
Let’s see some examples of chr() function to understand it’s functionality.
Python chr() Function Example 1
This is a simple example to use chr() function which returns char present at the specified int value. The return type is a string and can be verified as well.
-
# Python chr() function example
# Calling function
result = chr(102) # It returns string representation of a char
result2 = chr(112)
# Displaying result
print(result)
print(result2)
# Verify, is it string type?
print(“is it string type:”, type(result) is str)
Output:
- f
p
is it string type: True
Python chr() Function Example 2
The chr() function takes integer value in a range. It throws an error if the value exceeds the range. See the example below.
-
# Python chr() function example
# Calling function
result = chr(11) # It returns string representation of a char
result2 = chr(11111111) # If value is out of range
# Displaying result
print(result)
print(result2)
Output:
- ValueError: chr() arg not in range(0x110000)
Python chr() Function Example 3
See, we are applying a list of integers to the chr() function, and it returns char value of each integer point to the Unicode. See an example below.
-
# Python chr() function example
data = [112,97,114,119,115,10.5]
result = chr(11) # It returns string representation of a char
# Calling function
for d in data:
print(“Char at”,d,”is:”,chr(d))
Output:
- TypeError: integer argument expected, got float
Char at 112 is: p
Char at 97 is: a
Char at 114 is: r
Char at 119 is: w
Char at 115 is: s

I got my training from Zeblearn in the Python Certification Training, I would like to say that say he is one of the best trainers. He has not even trained me but also motivated me to explore more and the way he executed the project, in the end, was mind-blowing.
