Question

    dict1=({"EMP$$1":1,"EMP$$2":2,"EMP$$3":3})

How to check if EMP exists in the dictionary using python

   dict1.get("EMP##") ??

Answer 1

It’s not entirely clear what you want to do.

You can loop through the keys in the dict selecting keys using the startswith() method:

>>> for key in dict1:
...     if key.startswith("EMP$$"):
...         print "Found",key
...
Found EMP$$1
Found EMP$$2
Found EMP$$3

You can use a list comprehension to get all the values that match:

>>> [value for key,value in dict1.items() if key.startswith("EMP$$")]
[1, 2, 3]

If you just want to know if a key matches you could use the any() function:

>>> any(key.startswith("EMP$$") for key in dict1)
True
