how to write a hash function in python code example

Example: python hash function

# Hash Function 
# SHA hash algorithms. 

import hashlib 

# initializing string 
str = "TYCS"

# encoding TYCS using encode() 
# then sending to SHA1() 
result = hashlib.sha1(str.encode()) 

# printing the equivalent hexadecimal value. 
print("The hexadecimal equivalent of SHA1 is : ") 
print(result.hexdigest()) 

# encoding TYCS using encode() 
# then sending to SHA224() 
result = hashlib.sha224(str.encode()) 

# printing the equivalent hexadecimal value. 
print("The hexadecimal equivalent of SHA224 is : ") 
print(result.hexdigest())

# encoding TYCS using encode() 
# then sending to SHA256() 
result = hashlib.sha256(str.encode()) 

# printing the equivalent hexadecimal value. 
print("The hexadecimal equivalent of SHA256 is : ") 
print(result.hexdigest()) 

# initializing string 
str = "TYCS"

# encoding TYCS using encode() 
# then sending to SHA384() 
result = hashlib.sha384(str.encode()) 

# printing the equivalent hexadecimal value. 
print("The hexadecimal equivalent of SHA384 is : ") 
print(result.hexdigest()) 

# initializing string 
str = "TYCS" 

# initializing string 
str = "TYCS"

# encoding TYCS using encode() 
# then sending to SHA512() 
result = hashlib.sha512(str.encode()) 

# printing the equivalent hexadecimal value. 
print("The hexadecimal equivalent of SHA512 is : ") 
print(result.hexdigest())
