Python ASCII to String | In this post, we will discuss how to convert ASCII to string using the native method. We will also convert ASCII value to a string using list comprehension, Join(), and map() function.
ASCII stands for American Standard Code for Information Interchange. It was developed by the ANSI (American National Standards Institute) and it is used to interchange the information from a high-level language to low-level language. Machine or Computer understand only binary languages. So, the character data type represents integers. For example, the ASCII value of the letter ‘A’ is 65.
Convert ASCII to Text in Python
We are using the chr() function to convert ASCII to string. Which is a built-in function in Python that accepts a specified Unicode (ASCII value) as an argument and returns the character.
The syntax of chr() is:
chr(num)Where num will be an integer value.
chr() Parameters:
chr() method takes a single parameter, an integer i. The valid range of the integer is from 0 through 1,114,111.
Return value from chr():
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.
# Python program to conversion ASCII to string
# take list
l = [75, 110, 111, 119, 32, 80, 114, 111, 103, 114, 97, 109]
# printing list
print("List of ASCII value =", l)
# ASCII to string using naive method
string = ""
for num in l:
string = string + chr(num)
# Printing string
print ("String:", str(string))Output:-
List of ASCII value = [75, 110, 111, 119, 32, 80, 114, 111, 103, 114, 97, 109]

Python Program to Convert ASCII to String
This is yet another way to convert ASCII to string. This is just shorthand to the above program in which we compact the code using list comprehension. The list comprehension can help us iterating through the list.
# Python program to conversion ASCII to string
# take list
l = [75, 110, 111, 119, 32, 80, 114, 111, 103, 114, 97, 109]
# printing list
print("List of ASCII value =", l)
# ASCII to string using join() + list comprehension
string = ''.join(chr(num) for num in l)
# Printing string
print ("String:", str(string))Output:-
List of ASCII value = [75, 110, 111, 119, 32, 80, 114, 111, 103, 114, 97, 109]

ASCII to Text in Python
We are using the join() and map() function to convert ASCII to string. The map() is a built-in function that applies a function on all the items of an iterator given as input.
# Python program to conversion ASCII to string
# take list
l = [75, 110, 111, 119, 32, 80, 114, 111, 103, 114, 97, 109]
# printing list
print("List of ASCII value =", l)
# ASCII to string using join() + map()
string = ''.join(map(chr, l))
# Printing string
print ("String:", str(string))Output:-
List of ASCII value = [75, 110, 111, 119, 32, 80, 114, 111, 103, 114, 97, 109]
