Get position in list

You can do:

joursemaine.index('mardi')

which will return 1
(see http://diveintopython.adrahon.org/native_data_types/lists.html#d0e6152)
which is the most elegant version.

Generally speaking, you can always use brute force methods. If you were to iterate through a list with multiple occurrences of the same element, this method will only give you the first one, and you should consider using the enumerate() method while iterating through the list to retrieve both the element and the index.

for index,jour in enumerate(joursemaine): print index,jour

(see https://docs.python.org/3/tutorial/datastructures.html#looping-techniques)

Or we can simply do this:

for index, day in enumerate(list): print "the index ", index, " corresponds to the day ", day 

```python s=['lundi','mardi','mercredi','jeudi','vendredi','samedi','dimanche']
for i in range(0,len(s)):
if s[i]=='mardi':
print(i) ```

I think this is how it should work:

daysOfWeek = ['Monday','Tuesday','Wednesday','Thursday','Friday','Saturday','Sunday']

daysOfWeek[0] returns Monday
daysOfWeek[3] returns Thursday
....
There you go!
