How to Access Dictionary Elements by Index in Python?

Accessing Elements of a Python Dictionary by Index

Consider a dictionary like the one below, created by parsing an input file within a Python function:

mydict = {
  'Apple': {'American':'16', 'Mexican':10, 'Chinese':5},
  'Grapes':{'Arabian':'25','Indian':'20'}
}
Copy after login

How can we access specific elements of this dictionary without knowing the key in advance?

To access elements of a dictionary, we use the dictionary's keys. To get the dictionary stored under the key "Apple", use the following syntax:

mydict["Apple"]
Copy after login

This will return the following output:

{'American': '16', 'Mexican': 10, 'Chinese': 5}
Copy after login

To access a specific value within this sub-dictionary, use the following syntax:

mydict["Apple"]["American"]
Copy after login

This will return the value '16', which represents the number of American apples.

Therefore, to access the first element of the "Apple" sub-dictionary, which is "American" in this case, you can use the following code:

first_element = mydict["Apple"]["American"]
Copy after login
