Compressing multiple conditions in Python

Suppose I have a list of numbers mylist and that I would like execute some code if all the elements of mylist are greater than 10. I might try

if mylist[0] > 10 and mylist[1] > 10 and ... :
    do something

but this is obviously very cumbersome. I was wondering if Python has a way of compressing multiple conditions in an if statement. I tried

if mylist[i] > 10 for i in range(len(mylist)):
    do something

but this returned an error.

I am using Python 3.4.

Do it like this

if all(x > 10 for x in myList):

Your attempt is pretty close. You just needed the all function to examine the results of the expression.

if all(mylist[i] > 10 for i in range(len(mylist))):
    do something

Incidentally, consider iterating over the items of the list directly, rather than its indices.

if all(item > 10 for item in mylist):

The answer is all:

if all(item > 10 for item in mylist):
   do something
