Unlike sets, lists can contain duplicate values which can cause values when you need to convert them into a dictionary. To avoid errors from duplicate keys when converting a list to a dictionary, you can create a mechanism to handle the duplicate values. Take into consideration the following pr...
T07 - Show the data type of a list— You can inspect the output visually, as mentioned in taskT01. However, in some situations, it may be useful to validate that a variable contains the type of data you expect and even use that information to handle the data. [ Want to test your sy...
Python data type. It is a sequence of key-value pairs, where each key is unique and maps to a value. Dictionaries are mutable objects, meaning you can change their content without changing their identity. However, dictionary keys are immutable and need to be unique within each dictionary. Th...
You can use the built-in dir() function to get a list of methods and attributes that any Python object provides. If you run dir() with an empty dictionary as an argument, then you’ll get all the methods and attributes of the dict class:...
