Hash Map in Python

All you wanted (at the time the question was originally asked) was a hint. Here's a hint: In Python, you can use dictionaries.

Python dictionary is a built-in type that supports key-value pairs.

streetno = {"1": "Sachin Tendulkar", "2": "Dravid", "3": "Sehwag", "4": "Laxman", "5": "Kohli"}

as well as using the dict keyword:

streetno = dict({"1": "Sachin Tendulkar", "2": "Dravid"}) 

or:

streetno = {}
streetno["1"] = "Sachin Tendulkar" 

It's built-in for Python. See dictionaries.

Based on your example:

streetno = {"1": "Sachine Tendulkar",
            "2": "Dravid",
            "3": "Sehwag",
            "4": "Laxman",
            "5": "Kohli" }

You could then access it like so:

sachine = streetno["1"]

Also worth mentioning: it can use any non-mutable data type as a key. That is, it can use a tuple, boolean, or string as a key.
