Question
What do these lines print?>>> a = { 'id': 89, 'name': "John" }>>> a.get('id')id‘id’a[‘id’]John89
Solution
The code provided is written in Python. Here's what each line does:
-
a = { 'id': 89, 'name': "John" }- This line creates a dictionary namedawith two key-value pairs: 'id' with a value of 89 and 'name' with a value of "John". -
a.get('id')- This line retrieves the value associated with the key 'id' in the dictionarya. In this case, it will return 89. -
id- This line will cause an error if it is run as is. In Python,idis a built-in function that returns the identity of an object. It is not related to the 'id' key in the dictionarya. -
'id'- This line will simply print the string 'id'. -
a['id']- This line also retrieves the value associated with the key 'id' in the dictionarya, similar toa.get('id'). It will return 89. -
John- This line will cause an error if it is run as is. Python will interpretJohnas a variable name, not a string. If you want to print the string "John", you should put it in quotes:"John". -
89- This line will simply print the number 89.
