strings
|
Strings are, well, strings of characters, which is a more formal way of saying they're really just regular English phrases.
|
|
escaped
|
marked as unique
|
|
method
|
A method is a function of a specific object. A function is a piece of code that solves a particular problem or performs a specific task. For now, the takeaway is that string methods are pre-built pieces of code that perform specific tasks for strings.
|
|
len()
|
returns the length—that is, the number of characters—of the string on which it's called.
example: len(parrot) |
|
lower()
|
returns a lower-cased output of the string
example: parrot.lower() |
|
upper()
|
returns an upper-case output of the string
example: parrot.upper() |
|
str()
|
The str() method returns a string containing a nicely printable representation of whatever you put between the parentheses.
example: str(pi) |
|
dot notation
|
Dot notation works on string literals ("The Ministry of Silly Walks".upper()) and variables assigned to strings (ministry.upper()) because these methods are specific to strings—that is, they don't work on anything else. By contrast, len() and str() can work on a whole bunch of different objects (which we'll get to later), so they can't be tied just to strings with dot notation.
|
|
print
|
prints the result of the interpreter's evaluation of your code to the console for you to see.
example: print "monty_python" |
|
concatenate
|
brings strings together using the + sign
example: "Monty " + "Python" will return "Monty Python" |
|
explicit string conversion
|
using the str() method to convert non-strings into strings
|
|
implicit string conversion
|
putting quotes around a sequence of characters to make it a string
|
|
sting formatting
(%s) |
name = raw_input("What is your name?")
quest = raw_input("What is your quest?") color = raw_input("What is your favorite color?") print "Ah, so your name is %s, your quest is %s, \ and your favorite color is %s." % (name, quest, color) |
