Each key-value pair is enclosed in parentheses, letting the function know they should be grouped together. There is no best way to create a dictionary; some approaches may be easier in some cases, but the approach you use will mostly be a matter of aesthetics....
Adding an argument is straightforward: you simply insert the argument’s name between the parentheses on thedefline. This argument name then becomes a variable in the function’s suite. This is an easy edit. Let’s also remove the line of code that prompts the user to supply a word to s...
>>> a = "python" >>> b = "javascript" >>> assert a == b Traceback (most recent call last): File "<stdin>", line 1, in <module> AssertionError >>> assert (a == b, "Values are not equal") <stdin>:1: SyntaxWarning: assertion is always true, perhaps remove parentheses? >...
Now, just for fun, let’s try generating some random text in the various styles we have just seen. To do this, we type the name of the text followed by the term generate. (We need to include the parentheses, but there’s nothing that goes between them.) >>>text3.generate() Note ...
Step between Python and native code Visual Studio provides the Step Into (F11) or Step Out (Shift+F11) commands to enable the mixed-mode debugger to correctly handle changes between code types. When Python calls a method of a type implemented in C, stepping in on a call to that metho...
Sometimes strings go over several lines. Python provides us with various ways of entering them. In the next example, a sequence of two strings is joined into a single string. We need to use backslash①or parentheses②so that the interpreter knows that the statement is not complete after the...

Visual Studio provides theStep Into(F11) orStep Out(Shift+F11) commands to enable the mixed-mode debugger to correctly handle changes between code types. When Python calls a method of a type implemented in C, stepping in on a call to that method stops at the beginning of the native functi...
A tuple by using commas and optional parentheses A dictionary or set by using curly brackets ({}) For all but sets, you access a single element with square brackets. For the list and tuple, the value between the square brackets is an integer offset. For the dictionary, it’s a key. ...
