you have 10 minutes😂 Good luck!!
1. What is PEP8 ?
2. What are the different ways to distribute some python source code ?
2 Lists
Let's define the function plural :
def plural(words):
plurals = []
for word in words:
plurals.append(word + 's')
return plurals
for word in plural(['cabagge','owl','toy']):
print word
Question : How could the code of the function plural be optimised?
3 Dictionaries
Here are two dictionnaries :
input = {
'foo1': 'bar1',
'chose': 'truc',
'foo2': 'bar2',
}
output = {
'bar1': 'foo1',
'truc': 'chose',
'bar2': 'foo2'
}
Question : Propose a function that returns output when you provide input ?
4 Iterators
Let's consider this program :
def program_1():
yield 1
yield 2
yield 3
g = program_1()
a = list(g)
b = list(g)
c = g()
Question : At the end of the program,
1. What is the type of g ?
2. What is the value of a ?
3. What is the value of b ?
4. What is the value of c ?
5 Decorators
Let's consider now :
def str2print(f):
def str2print_wrap(*args, **kwargs):
"""wrapper"""
s = f(*args, **kwargs)
print s
return str2print_wrap
def hello(s):
""" Return "Hello $s" """
return "%s %s" % ("Hello", s)
Questions :
1. Decorate the method 'hello' with 'str2printf' and write the corresponding
code.
2. What is the effect of the decorator on a call to the new method 'hello' ?
3. What is the return value of hello.__doc__
