If a value for one of the keys in my dictionary does satisfies a condition, I want to break out of the loop and set a property to True.
what I'm doing so far is:
fooBar = False
for key, value in my_dict.items():
if (condition):
fooBar = True
Do I need to use a for loop and iterate through all items in the dictionary, or can I use a while loop?

In order to iterate only over keys you need to call keys() method that returns a new view of the dictionary's keys.
To calculate the length of a dictionary, we can use the Python built-in len() method. The len() method returns the number of keys in a Python dictionary.
Answer. Yes, you can use a function call in the while expression. If calling only a function in the expression, it should return True or False . If the function is part of a more complex expression, then the end result of the expression should evaluate to True or False .
Python dictionaries can be used when the data has a unique reference that can be associated with the value. As dictionaries are mutable, it is not a good idea to use dictionaries to store data that shouldn't be modified in the first place.
You don't have to continue iterating over the entire dictionary - you could just break out of the loop:
fooBar = False
for key, value in my_dict.items():
if (condition):
fooBar = True
break # Here!
