Python Program to Print ASCII Value



« Previous Program Next Program »


In this article, I've created some programs in Python, that find and prints ASCII value(s) in following ways:

Find and Print ASCII Value of a Character

This program find and prints ASCII value of a particular character entered by user at run-time. The ord() method returns ASCII value of a character passed as its argument, like shown in the program given below:

# ----codescracker.com----

print("Enter a Character: ")
ch = input()

asc = ord(ch)
print("\nASCII Value:", asc)

Here is its sample run:

ascii values python

Now supply the input say c and press ENTER key to find and print the ASCII value 'c' (entered character by user) as shown in the snapshot given below:

python print ascii values

Modified Version of Previous Program

The end skips inserting an automatic newline using print(). The str() converts any type of value to string type. The len() returns length of a string passed as its argument. The \" is used to print "

# ----codescracker.com----

print("Enter a Character: ", end="")
ch = input()

chlen = len(ch)
if chlen==1:
    asc = ord(ch)
    print("\nASCII Value of \"" +(ch)+ "\" = " +str(asc))
else:
    print("\nInvalid Input!")

Here is its sample run with user input Z:

print ascii value of character

Here is another sample run with user input codescracker. Since it is not a character, rather it is a string, therefore the program produces following output. At last of this article, I've created a program that prints ASCII value of anything like character, string, etc.

print ascii values

Print ASCII Values of all Characters

This program prints ASCII value of all 255 characters:

# ----codescracker.com----

print("ASCII\tCharacter")
for i in range(256):
    ch = chr(i)
    print(i, "\t\t", ch)

The snapshot given below shows a small part of the output produced by above Python:

print all ascii values of characters in python

The following code from above program:

for i in range(256):

states that the statements inside it gets executed 256 number of times with value of i from 0 to 255.

Find and Print ASCII Value of all Characters in String

This program find and prints ASCII value of all characters in a string entered by user.

# ----codescracker.com----

print("Enter a String: ", end="")
text = input()

textlen = len(text)
for ch in text:
    asc = ord(ch)
    print(ch, "\t", asc)

Here is its sample run with input, CodesCracker:

list of all character with their ascii values

Here is another sample run with user input as codes123%#4/|]{

python display ascii values

Modified Version of Previous Program

The previous program is modified because that program prints ASCII value of c from string say codescracker three times. Since there are three c available in this string. But this program prints ASCII value of all characters for only one time, without mattering whether the character occurs one or more times in the string:

# ----codescracker.com----

print("Enter a String: ", end="")
text = input()

text = "".join(dict.fromkeys(text))
textlen = len(text)
for ch in text:
    asc = ord(ch)
    print(ch, "\t", asc)

Here is its sample run with string user input as codescracker.com:

python find ascii values of characters

Note - In above program, the statement text = "".join(dict.fromkeys(text)), removes duplicate characters from the string entered by user, stored in text.

Note - Dictionary does not allows duplicates.

Same Program in Other Languages
