python list attributes code example

Example 1: python list methods

list.append(x) # append x to end of list
list.extend(iterable) # append all elements of iterable to list
list.insert(i, x) # insert x at index i
list.remove(x) # remove first occurance of x from list
list.pop([i]) # pop element at index i (defaults to end of list)
list.clear() # delete all elements from the list
list.index(x[, start[, end]]) # return index of element x
list.count(x) # return number of occurances of x in list
list.reverse() # reverse elements of list in-place (no return)
list.sort(key=None, reverse=False) # sort list in-place
list.copy() # return a shallow copy of the list

Example 2: see attributes of object python

>>> class new_class():
...   def __init__(self, number):
...     self.multi = int(number) * 2
...     self.str = str(number)
... 
>>> a = new_class(2)
>>> a.__dict__
{'multi': 4, 'str': '2'}
>>> a.__dict__.keys()
dict_keys(['multi', 'str'])

Example 3: how to get all values from class in python

>>> an = Animal()
>>> attrs = vars(an)
#{'kids': 0, 'name': 'Dog', 'color': 'Spotted', 'age': 10, 'legs': 2, 'smell': 'Alot'}
