Find the Access Codes Write a function answer(l) that takes a list of positive integers l and counts the number of “lucky triples” of (lst[i], lst[j], lst[k]) where i < j < k. The length of l is between 2 and 2000 inclusive. The elements of l are between 1 and 999999 inclusive. The answer fits within a signed 32-bit

Python regex iteration for all combinations
I am new to regex. I am using Python 2.7 and BeautifulSoup4. I want to iterate over a particular regular expression. Required ouput : length : 5 , expression : [a-zA-Z0-9!&#%@] It should try all possible combinations e.g: [‘aaaaa’,’aaaab’,’aaaac’,…,’aaaaz’,’aaaaA’,…,’aaaaZ’,’aaaa0′,’aaaa9′,’aaaa!’,’AAA!!’] Moreover this should be possible too. If the expression is oranged{1} [‘orangea’,’oranges’]] I tried this: I realized that this is a
All possible points of (latitude,longitude) from latitude/longitude coordinates in separate arrays
I have latitude and longitude coordinates in two separate arrays: How can I easily find all possible points made up of these coordinates? I’ve been messing around with itertools.combinations: but this doesn’t work for me because the points (71,75) and (43,42) are latitude/latitude and longitude/longitude pairs. What I would like to have is this: The a and b arrays will
