You use zip() to unzip the content of sales into two variables: x holds a list of fruits. y holds the corresponding units sold per fruit. Then you create a bar chart using plt.bar(). When you run plt.show(), you get a window like the following on your screen: In this chart...
Numbers: int, float, complex Strings: str Booleans: bool Lists: list Tuples: tuple Dictionaries: dict Sets: setExamplesHere is an example of how to use the Python data types.# Integer a = 10 # Float b = 3.14 # String c = "Hello" # Boolean d = True # List e = [1, 2, 3,...
The double-asterisk in front of a dictionary object lets you pass the contents of that dictionary asnamed arguments to a function. The dictionary’s keys are the argument names, and the values are the values passed to the function. You don’t even need to call itkwargs!
