Final answer:
The function 'find_key' in Python checks if the key 'tropical' exists in a dictionary and returns True if it does, otherwise False.
Step-by-step explanation:
The function find_key you're looking to write in Python will check whether a given object, or more accurately in Python terms, a dictionary, has a specific key, which in this case is the string "tropical". To do this, you'll utilize the in keyword which checks for the existence of a key in a dictionary.
A python program is made of many lines of code, stored in a file with a name like "example.py". It's natural to have a way to divide the lines code up into sensible sub-parts, and these are called functions. Almost all the code you work with in Python is inside a function. This article explains different types of Functions in Python.
The functions explained are Built-in Functions, User-defined Functions, Recursive Functions, Lambda Function. A function is a block of code in Python that performs a particular task. Here's an example of how you might define the function: def find_key(my_dict): return 'tropical' in my_dict. This function will return True if 'tropical' is indeed a key in the provided dictionary my_dict, and False otherwise.
