Python equivalent for HashMap

Question

I’m new to python. I have a directory which has many subfolders and files. So in these files I have to replace some specified set of strings to new strings. In java I have done this using HashMap. I have stored the old strings as keys and new strings as their corresponding values. I searched for the key in the hashMap and if I got a hit, I replaced with the corresponding value. Is there something similar to hashMap in Python or can you suggest how to go about this problem.

To give an example lets take the set of strings are Request, Response. I want to change them to MyRequest and MyResponse. My hashMap was

Key -- value
Request -- MyRequest
Response -- MyResponse

I need an equivalent to this.

You need a dict:

my_dict = {'cheese': 'cake'}

Example code (from the docs):

>>> a = dict(one=1, two=2, three=3)
>>> b = {'one': 1, 'two': 2, 'three': 3}
>>> c = dict(zip(['one', 'two', 'three'], [1, 2, 3]))
>>> d = dict([('two', 2), ('one', 1), ('three', 3)])
>>> e = dict({'three': 3, 'one': 1, 'two': 2})
>>> a == b == c == d == e
True
