Python - Code Academy Course - Strings And Console Output

Front 1

strings

Back 1

Strings are, well, strings of characters, which is a more formal way of saying they're really just regular English phrases.

Front 2

escaped

Back 2

marked as unique

Front 3

method

Back 3

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.

Front 4

len()

Back 4

returns the length—that is, the number of characters—of the string on which it's called.

example: len(parrot)

Front 5

lower()

Back 5

returns a lower-cased output of the string

example: parrot.lower()

Front 6

upper()

Back 6

returns an upper-case output of the string

example: parrot.upper()

Front 7

str()

Back 7

The str() method returns a string containing a nicely printable representation of whatever you put between the parentheses.

example: str(pi)

Front 8

dot notation

Back 8

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.

Front 9

print

Back 9

prints the result of the interpreter's evaluation of your code to the console for you to see.

example: print "monty_python"

Front 10

concatenate

Back 10

brings strings together using the + sign

example: "Monty " + "Python" will return "Monty Python"

Front 11

explicit string conversion

Back 11

using the str() method to convert non-strings into strings

Front 12

implicit string conversion

Back 12

putting quotes around a sequence of characters to make it a string

Front 13

sting formatting

(%s)

Back 13

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)
