agenda • History & Basics • Advanced & Be Pythonic
• Awesome Python Frameworks
Advanced & Be Pythonic
Review • int & float & bool • string &
list & tuple • dict • loop & branch • def methods
Something interesting…
def foo(a, b): """My niubility methods.""" return a + b
"""My niubility methods.""" >>> print foo.__doc__ >>> My niubility methods.
class Person(object): """My first class""" version = 1.0 def __init__(self,
name): self.name = name print "__init__ called" def get_name(self): """Return the name""" return self.name
Pythonic
–Martijn Faassen, founder of the lxml (XML library for Python)
“Pythonic is to use the Python constructs and datastructures with clean, readable idioms.”
enumerate l = [0, 1, 2, 3, 4] for i
in range(len(l)): print i, l[i] for i, element in enumerate(l): print i, element
value exchange temp = foo foo = bar bar =
temp foo, bar = bar, foo
string concatenating s = “hello” + “world” s = “”.join([“hello”,
“world”])
λ
lambda def foo(x): return x ** 2 lambda x :
x ** 2 >>> a = lambda x : x ** 2 >>> a(5) >>> 25
filter & map & reduce
>>> filter(function, iterable) >>> map(function, iterable) >>> reduce(function, iterable)
filter
map
reduce
None
List comprehensions
>>> a = map(lambda x : x ** 2, range(10))
>>> a = [ x ** 2 for x in range(10)] >>> a = filter(lambda x : x % 2, range(10)) >>> a = [x for x in range(10) if x % 2]
None
