python ascii code to string with code examples

Python provides several ways to convert ASCII codes to strings. One common method is to use the chr() function, which takes an ASCII code as its argument and returns the corresponding character. For example, the code chr(97) would return the string "a", because the ASCII code for "a" is 97.

Another way to convert ASCII codes to strings is to use the bytes.fromhex() function, which takes a hexadecimal string as its argument and returns the corresponding bytes object. For example, the code bytes.fromhex("61") would return the bytes object b'a', because the hexadecimal representation of the ASCII code for "a" is 61.

You can also use the ord() function to convert a single character to its ASCII code. For example, ord('a') would return the integer 97.

Here's an example of a complete program that uses the chr() function to convert a list of ASCII codes to a string:

# define a list of ASCII codes
codes = [97, 98, 99]

# convert the codes to a string
result = ""
for code in codes:
    result += chr(code)

print(result)

This will output the string "abc".

You can also use the map() function and join() function to achieve the same result

codes = [97, 98, 99]
result = "".join(map(chr, codes))
print(result)

In addition to the above methods, you can also use the bytes.decode() method to convert a bytes object to a string, where the bytes object contains the ASCII codes.

codes = b'abc'
result = codes.decode()
print(result)

In Python, the bytes class contains a set of integers in the range of 0 – 255, and each integer represents the ASCII code of a character. Therefore, it is possible to convert the bytes object to string by calling the decode() method.

In conclusion, Python provides several ways to convert ASCII codes to strings, including the chr(), bytes.fromhex(), ord(), join(), map() and bytes.decode() functions. Each method has its own advantages and disadvantages, and the best method to use will depend on the specific requirements of your program.

In addition to converting ASCII codes to strings, Python also provides several ways to convert strings to ASCII codes. One common method is to use the ord() function, which takes a single character as its argument and returns the corresponding ASCII code. For example, the code ord("a") would return the integer 97, because the ASCII code for "a" is 97.

You can also use the bytes() function to convert a string to a bytes object containing the ASCII codes. For example, the code bytes("abc", "ascii") would return the bytes object b'abc', which contains the ASCII codes for the characters "a", "b", and "c".

Another way to convert a string to ASCII codes is by using a list comprehension, where each element in the list is the ASCII code of a character in the string. For example:

string = "abc"
codes = [ord(c) for c in string]
print(codes)

This will output the list of integers [97, 98, 99], which are the ASCII codes for the characters "a", "b", and "c".

It's also possible to use the bytearray() function to convert a string to a bytearray object containing the ASCII codes. This is similar to the bytes() function, but a bytearray object is mutable, meaning the contents can be modified after it's created.

string = "abc"
codes = bytearray(string, 'ascii')
print(codes)

This will output the bytearray object bytearray(b'abc'), which contains the ASCII codes for the characters "a", "b", and "c".

In addition to the above methods, it is also possible to use the str.encode() method to convert a string to bytes object containing the ASCII codes.

string = "abc"
codes = string.encode('ascii')
print(codes)

This will output the bytes object b'abc', which contains the ASCII codes for the characters "a", "b", and "c".

In conclusion, Python provides several ways to convert strings to ASCII codes, including the ord(), bytes(), bytearray(), str.encode() functions and list comprehension. Each method has its own advantages and disadvantages, and the best method to use will depend on the specific requirements of your program. For example, if you need to modify the contents of the bytes object, you should use the bytearray() function. If you need to maintain the immutability, then you should use the bytes() function.
