In the preceding code, variable x is assigned to a complex number q. real. Several built-in functions can operate on numbers. 49) 4 q Built-in function w Library module function Built-in functions are always available and are called using a standard function calling syntax. In the preceding code, round is called with a float as its input argument q. The functions in library modules are made available using the import statement. function(arguments). com> 21 Built-in data types Other than their representation as True and False, Booleans behave like the numbers 1 (True) and 0 (False) q.
They’re also more efficient to use when you don’t need modifiability. 0, ["a", "b"], (5, 6)) q w A one-element tuple q needs a comma. A tuple, like a list, can contain a mixture of other types as its elements, including strings, tuples, lists, dictionaries, functions, file objects, and any type of number w. 4 Strings String processing is one of Python’s strengths. """ Strings can be delimited by single (' '), double (" "), triple single (''' '''), or triple double (""" """) quotations and can contain tab (\t) and newline (\n) characters.
3 Using the Python shell in IDLE. q Code is automatically colored (based on Python syntax) as it’s typed in. w Here I typed f and then pressed Alt-/, and automatic completion finished the word factorial. e I lost the prompt, so I pressed Ctrl-C to interrupt the interpreter and get the prompt back (a closed bracket would have worked here as well). r Placing the cursor on any previous command and pressing the Enter key moves the command and the cursor to the bottom, where you can edit the command and then press Enter to send it to the interpreter.
