The f-string formats each argument as key=value, and again, you use repr() to represent the value. Line 11: You join together the lists of positional and keyword arguments to one signature string with each argument separated by a comma. Line 14: You print the return value after the ...
To separate the headers from the table’s content, you build a line of hyphens. To create the line, you use the repetition operator with the maximum header length as the multiplier operand. The effect of using the operator here is that you’ll get a visual line under each header that’...
The "print" operator prints out one or more python items followed by a newline (leave a trailing comma at the end of the items to inhibit the newline).A "raw" string literal is prefixed by an 'r' and passes all the chars through without special treatment of backslashes, so r'x\nx...
In addition, each subclass of AudioFile implements play() in a different way (this example doesn't actually play the music; audio compression algorithms really deserve a separate book!). This is also polymorphism in action. The media player can use the exact same code to play a file, no ...
Arguments are specified after the function name, inside the parentheses. You can add as many arguments as you want, just separate them with a comma. The following example has a function with one argument (fname). When the function is called, we pass along a first name, which is used ins...
Because there's acatch-allcondition, try using any other string as the destination to check that behavior: Python distance_from_earth("Saturn") Output Unable to compute to that destination Multiple required arguments To use multiple arguments, you must separate them by using a comma. Let's cre...

Lastly, an important application of strings is thesplitmethod, which returns a list of all the words in the initial string and it automatically splits by any white space. It can optionally take a parameter and split the strings by another character, like a comma or a dot ...
pandas accepts any ``os.PathLike``.By file-like object, we refer to objects with a ``read()`` method, such asa file handle (e.g. via builtin ``open`` function) or ``StringIO``.sep : str, default ','Delimiter to use. If sep is None, the C engine cannot automatically detect...
these are of the same category, here, anumber. A similar thing happens with a variable name: the classification into a variable is sufficient, and the variable name is not needed in parsing. For punctuation though, comma, colon, and semicolon are different so those do need to be separate...
