add method to convert string to md5 in python

To add a method to convert string to MD5 in Python, we need to use the hashlib library. hashlib is a built-in library that provides various hashing algorithms like MD5, SHA-1, etc.

Here's an example code block that demonstrates how to create a method that takes a string and returns its MD5 hash value:

main.py
import hashlib

def get_md5(string):
    """
    This function takes a string as input and returns its corresponding MD5 hash value.
    """
    # creating an MD5 hash object
    md5_obj = hashlib.md5()

    # encoding the input string into bytes and updating the md5 object
    md5_obj.update(string.encode())

    # fetching the hexadecimal representation of hash value
    hex_dig = md5_obj.hexdigest()

    # returning the hexadecimal form
    return hex_dig
463 chars
18 lines

In the above code, we've created a function called get_md5 which takes a string as input and returns its corresponding MD5 hash value. We first create an md5 object using hashlib.md5(), then encode the input string using .encode() and update the md5 object using .update(). Finally, we obtain the hexadecimal digest of the hash using .hexdigest() and return it.

To use this method, simply call it with the string you want to hash:

main.py
string_to_hash = "Hello World!"
md5_hash = get_md5(string_to_hash)
print("MD5 hash of", string_to_hash, "is:", md5_hash)
121 chars
4 lines

Output:

main.py
MD5 hash of Hello World! is: ed076287532e86365e841e92bfc50d8c
62 chars
