python hashmap code example
Example 1: python hash function
import hashlib
str = "TYCS"
result = hashlib.sha1(str.encode())
print("The hexadecimal equivalent of SHA1 is : ")
print(result.hexdigest())
result = hashlib.sha224(str.encode())
print("The hexadecimal equivalent of SHA224 is : ")
print(result.hexdigest())
result = hashlib.sha256(str.encode())
print("The hexadecimal equivalent of SHA256 is : ")
print(result.hexdigest())
str = "TYCS"
result = hashlib.sha384(str.encode())
print("The hexadecimal equivalent of SHA384 is : ")
print(result.hexdigest())
str = "TYCS"
str = "TYCS"
result = hashlib.sha512(str.encode())
print("The hexadecimal equivalent of SHA512 is : ")
print(result.hexdigest())
Example 2: hashmap python
my_dict={'Dave' : '001' , 'Ava': '002' , 'Joe': '003'}
print(my_dict.keys())
print(my_dict.values())
print(my_dict.get('Dave'))
Example 3: hash map in python
>>> from collections import ChainMap
>>> dict1 = {'one': 1, 'two': 2}
>>> dict2 = {'three': 3, 'four': 4}
>>> chain = ChainMap(dict1, dict2)
>>> chain
ChainMap({'one': 1, 'two': 2}, {'three': 3, 'four': 4})
>>> chain['three']
3
>>> chain['one']
1
>>> chain['missing']
KeyError: 'missing'
